CROSS-REFERENCE TO RELATED APPLICATIONS

The present application is a continuation-in-part of U.S. patent application Ser. No. 10/345,543 filed in the U.S. Patent and Trademark Office on Jan. 16, 2003 now U.S. Pat. No. 6,766,856.

FIELD OF THE INVENTION

An object of the invention is to remove cross-sectional detailed described below with reference to the listed Figures.

DETAILED DESCRIPTION OF THE PREFFERED EMBODIMENTS

Before explaining the present invention in detail, it is to be understood that the invention is not limited to the particular embodiments and that it can be practiced or carried out in various ways.

With reference to the Figures, FIG. 1, FIG. 2, FIG. 3, and FIG. 4 are representations of a choke and method for treating a flow stream from a well having large diameter particulate matter.

One of the benefits of this invention is that it can remove damaging solids from an oil well or natural gas stream so as not to damage down stream equipment, such as separators, pipe line and refining equipment, by inserting an integral solids receptacle into the chamber, the solids are easily and efficiently removed from the flow stream. In this design, the flow stream inlet is in one embodiment below the flow stream outlet from the choke, which makes it very difficult for heavier particles to rise up to the flow stream outlet, so using gravity and the natural circulation of the flow stream in the chamber, the large diameter heavier particulate matter is more easily trapped in the integral solids receptacle in the chamber.

Another benefit of the invention, is that the invention can reduce the velocity of the flow stream between 3 and 5 times the initial intake velocity into the housing of a choke. The benefit of the reduction of the velocity of the flow stream is again to restrict the ability of the large diameter particulate to reach the flow stream outlet, and drop out of the flow stream into the solids receptacle in the chamber of the housing of the choke.

Environmentally, the removal of large diameter particulate matter at this stream stops damage to equipment which can cause leakage into the environment, or explosions which can harm people down stream. Pollution from leakage caused by large particles jamming up pipelines is a serious problem, and the toxic clean up can be expensive and harmful to wildlife. The invention is designed to reduce these hazards and help solve these problems.

FIG. 1 depicts the side view of a choke (10) for a flow stream (50) from a well such as an oil or natural gas well having large diameter particulate matter (42). Typically, flow streams from these wells have a velocity up to 50 million cubic feet per day or even greater depending on the size of the well. The choke (10) can be a manual or a hydraulic choke and sustain up to 20,000 psi, typically between 5000 and 20,000 psi during operation. Examples of hydraulic chokes usable with this invention are those produced by Schooner Petroleum Service of Houston, Tex.

Large diameter particulate matter (42) have a diameter equivalent to or less than the diameter of the flow stream inlet (24). This diameter is termed hereafter the first diameter (28). The large diameter particulate matter (42) can be rock, iron pieces, rubber, composite materials or combinations thereof.

The choke (10) includes a housing (23) having a chamber (15) with an integral solids receptacle (30). The housing (23) can be made of steel, stainless steel, alloys thereof, coated steel or combinations thereof.

The chamber (15) is in communication with a flow stream outlet (51), and a flow stream inlet (24) having a first diameter(28). The chamber (15) can be between 3 to 5 times the diameter of the flow stream inlet (24). Typically the chamber (15) with integral solids receptacle (30) would hold between about 0.5 and 4 gallons of fluid.

In one embodiment, the flow stream inlet (24) is located in a plane below the flow stream outlet (51) as shown in FIG. 1, and directly adjoins the integral solids receptacle (30) in the chamber (15). The flow stream inlet (24) is preferably between 2 inches and 4 inches in diameter.

Also included is a solids removal outlet (39) located below the flow stream inlet (24) in communication with the chamber (15) for flowing large diameter particulate matter (42) from the chamber (15) when actuated by a user (53). An outlet plug (40) can be inserted in one embodiment into the solids removal outlet (39) and can be made of the same material as the housing (23). FIG. 1 shows element (70) as the threads for the threaded engagement between the outlet plug (40) and the solids removal outlet (39).

FIG. 1 further depicts an outlet plug (40) which is connected to the solids removal outlet (39), and can be in a threaded engagement with the solids removal outlet (39). The choke (10) may in another embodiment include a sleeve (27) that is a different and harder material than the housing (23). The sleeve (27) can comprise a tungsten carbide, a steel, similar hard material, or combinations thereof. The sleeve is expected to be between about ⅛ inch and ¾ inch, preferably ¼ inch in thickness.

The sleeve can be 6 inches long, or at least as long as the flow stream outlet (51).

FIG. 1 further depicts a needle (20) disposed in a bonnet (18). The needle (20) engages a choke face (26). In this embodiment, the bonnet and needle are connected to the chamber (15) above the flow stream inlet (24) for controlling the flow stream (50) from the flow stream inlet (24) to the flow stream outlet (51). The choke face (26) is in a seat (22) in a preferred embodiment. The choke face, when closed can provide a sealing engagement with the needle. The needle (20) can be a hydraulically actuated needle for removably engaging the choke face (26), or mechanically engaged using a hand wheel (52). The bonnet (18) is in a threaded engagement with the housing (23) to hold the needle (20). In an alternative embodiment, the flow stream inlet (24) can be in the same plane as the flow stream outlet (51) and in that embodiment, the needle and bonnet are connected to the chamber in the same plane as the flow stream outlet. FIG. 1 shows element (60) as the threads for the threaded engagement between the bonnet (18) and housing (23). FIG. 1 shows the cleaned flow stream (54). A hydraulic choke actuator (90) is also depicted in FIG. la.

FIG. 2 depicts the top view of the an embodiment of a choke (10) for a flow stream (50) from a well such as an oil or natural gas well having large diameter particulate matter (42) as shown in FIG. 1.

The choke (10) includes a housing (23) having a chamber (15). The chamber (15) is in communication with a flow stream outlet (51) and a flow stream inlet (24) with a first diameter (28). The flow stream inlet (24) is located in a plane below of the flow stream outlet (51).

FIG. 2 further depicts a needle (20) disposed in a bonnet (18) is connected to the chamber (15) above the flow stream inlet (24) for controlling the flow stream (50) from the flow stream inlet (24) to the flow stream outlet (51) by engaging a choke face (26) with the needle (20). The choke face has a seat (22). FIG. 2 shows element (60) as the threads for the threaded engagement between the bonnet (18) and housing (23). FIG. 2 shows the cleaned flow stream (54).

In an alternative embodiment, the flow stream inlet can be on the same or identical plane as below the flow stream outlet.

FIG. 3 depicts a dump device (100) which can be used instead of the outlet plug (40) as an alternative embodiment. The dump device (100) is connected to the solids removal outlet (39). The dump device (100) includes a pipe (101) connected to the solids removal outlet (39) and a controllable valve (102) for controlling flow out of the solids removal outlet (39). An example of a usable controllable valve would be a gate or plug valve made by Schooner Petroleum Services of Houston, Tex., Halliburton or Cameron gate valve of Houston, Tex. The controllable valve (102) could also be another choke. The pipe can have a diameter of between about 2 inches and 4 inches and is made out the same material as the housing. The dump device (100) can be flanged to the solids removal outlet, but it could be a studded engagement, threaded engagement or clamped to the solids removal outlet (39). The dump device (100) could be an automatically actuating dump device based on a sensor which determines the quantity of large diameter particulate matter (42) in the solids removal outlet (39). The dump device (100) could be solar electrically operated using solar panels or could be connected to batteries or another power source. The dump device (100) can also be operated by a user (53) for intermittent dumping of the large diameter particulate matter (42).

FIG. 4 depicts a detailed view of the needle (20) engaging the choke face (26) with the seat (22). The needle (20) and choke face (26) are ground and polished so that upon mating form a positive seal for complete shut off.

The invention also relates to a method for removing large diameter particulate matter (42) from a flow stream (50) from an oil or natural gas well, which includes flowing a flow stream (50) into a flow stream inlet (24) with a first diameter (28) communicating with an integral a solids receptacle (30) in a chamber (15). The flow stream is from a production well, drilling well or combinations thereof. The velocity of the flow stream is reduced significant significantly as it moves from the flow stream inlet (24) to the flow stream outlet (51), and is reduced between about 3 and 5 times from the flow velocity at the flow stream inlet (24) to the flow velocity at the flow stream outlet (51).

The chamber (15) is in communication with a flow stream outlet (51) and the flow stream inlet (24) is located on a plane below the flow stream outlet (51). The method also permits large diameter particulate matter (42) to fall from the flow stream inlet (24) into the integral solids receptacle (30). A stream is formed without large diameter particulate matter (42). This stream is then flowed flows to the flow stream outlet. A needle (20) and choke face (26) are used to control the flow velocity of the flow stream, which is a hydrocarbon stream without large diameter particulate solids out of the chamber (15) to the flow stream outlet.

The method allows, periodically, interrupting the flow stream by engaging the needle (20) with the choke face (26) to remove additional large diameter particulate matter (42) which are still circulating from in the chamber (15). On necessity, the method allows removing the large diameter particulate matter (42) from the integral solids receptacle (30) in the chamber (15) through the solids removal outlet (39). Additionally, the method allows for a step of forming a sealing engagement between the choke face (26) and the needle (20) using a seat (22).

In an alternative embodiment, the method allows for the chamber to be in communication with a flow stream outlet (51), and the flow stream inlet (24) is located on a same plane or is identical to the flow stream outlet (51).

While this invention has been described with emphasis on the preferred embodiments, it should be understood that within the scope of the appended claims, the invention might be practiced other than as specifically described herein.
