[0001] The utility model relates to the technical field of gas well ball dropping, particularly relates to a ball storage cylinder for piston type gas well ball dropping. BACKGROUND

[0002] With the long-term development of gas reservoir, the formation energy is continuously reduced and the condensate water is continuously separated out, resulting in the increase of liquid accumulation in the gas well. In order to solve the problem of affecting production due to wellbore liquid accumulation, the commonly used measure is to drop foam balls into the wellbore. The foam balls are not easy to be stuck during falling and can sink to a deep position in the wellbore. The foam balls dissolve from inside to outside, and the water carried by the foam is discharged from the wellbore to the ground along with the gas flow, achieving the purpose of stable production and increased production by discharging wellbore liquid.

[0003] In the prior art, through consulting relevant information, it is understood that the piston type gas well head ball device used at present generally has a ball storage cylinder assembled thereon.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4The diagram shows a ball storage cylinder for piston-type gas well ball launching, comprising a ball storage cylinder 100. The ball storage cylinder 100 includes a lower cylinder 102 and an upper cylinder 101. The ball storage cylinder 100 adopts a split structure of the upper cylinder 101 and lower cylinder 102, and is equipped with a telescopic protective component between them. This component maintains a closed position between the two while allowing for length adjustment, thus enabling adjustment of the length of the ball storage cylinder 100 and the depth of the ball storage space within the inner wall of the ball storage cylinder 100. This allows the ball storage cylinder 100 to adjust its length and cavity depth according to usage requirements, increasing its adaptability. A mounting flange 300 is fixedly installed at the bottom end of the lower cylinder 102 for fixed assembly of the ball storage cylinder 100 onto the ball launching device. The upper cylinder 101 is located at the end of the lower cylinder 102 away from the mounting flange 300. The lower cylinder 102 and the upper cylinder... All bodies 101 are hollow cylindrical bodies with both ends connected. A telescopic protective assembly is set between the upper cylinder 101 and the lower cylinder 102. The telescopic protective assembly is used to wrap the area between the upper cylinder 101 and the lower cylinder 102. The telescopic protective assembly includes a corrugated pipe 103. The two ends of the corrugated pipe 103 are fixedly connected to the opposite ends of the upper cylinder 101 and the lower cylinder 102, respectively. The inner diameter of the corrugated pipe 103 is larger than the inner diameter of the upper cylinder 101 and the lower cylinder 102. By using the corrugated pipe 103 to connect the area between the upper cylinder 101 and the lower cylinder 102, the telescopic characteristics of the corrugated pipe 103 can be used to wrap and protect the area between the upper cylinder 101 and the lower cylinder 102, so that the bubble bouncy balls will not deviate or leak during the process of entering the lower cylinder 102 from the upper cylinder 101, thereby improving the stability of the bubble bouncy balls in the storage cylinder 100.

[0025] Furthermore, the adjusting mechanism 200 is disposed on the side wall of the upper cylinder 101 and the lower cylinder 102, and is used to adjust the distance between the upper cylinder 101 and the lower cylinder 102; wherein, the adjusting mechanism 200 includes an internally threaded tube 201 and an externally threaded rod 202, the internally threaded tube 201 is movably disposed on one side of the lower cylinder 102, and the externally threaded rod 202 is fixedly disposed on one side of the upper cylinder 101, the outer wall of the externally threaded rod 202 being threadedly connected to the inner side of the internally threaded tube 201; in specific adjustment operations When the internal thread tube 201 is rotated manually, the external thread rod 202 remains relatively fixed with the upper cylinder 101. When the internal thread tube 201 rotates clockwise or counterclockwise, it will drive the external thread rod 202 to move up or down, causing the length between the external thread rod 202 and the internal thread tube 201 to change. This allows for adjustment of the distance between the upper cylinder 101 and the lower cylinder 102, while ensuring self-locking of the adjusted position and preventing automatic return to the original position, thus improving the stability of the adjustment.

[0026] In a preferred embodiment, connecting seats 203 are fixedly connected to the opposite ends of the outer walls of the upper cylinder 101 and the lower cylinder 102. Fasteners are provided on both sides of the connecting seats 203 near the ball storage cylinder 100, facilitating the assembly and disassembly of the connecting seats 203 from the upper cylinder 101 and the lower cylinder 102 using screws. The connecting seat 203 located on the side wall of the upper cylinder 101 is fixedly connected to the end of the externally threaded rod 202 away from the internally threaded tube 201. A seated bearing 204 is rotatably connected to the end of the external threaded rod 202. A connecting seat 203 located on the side wall of the lower cylinder 102 is fixedly connected to the seated bearing 204. The seated bearing 204 allows the internal threaded tube 201 to be rotatably installed on the connecting seat 203. An auxiliary handle 205 is fixedly connected to the outer wall of the internal threaded tube 201. The auxiliary handle 205 can be made of rubber or have anti-slip texture added to its outer wall to improve the comfort and convenience of manually rotating the internal threaded tube 201.

[0027] Furthermore, a guide mechanism is provided between the upper cylinder 101 and the lower cylinder 102. This guide mechanism guides the movement of the volleyball between the upper cylinder 101 and the lower cylinder 102. The guide mechanism includes linear tenons 104 and linear tenons 105. Multiple linear tenons 104 are arranged in a circular array and spaced apart on the inner wall of the lower cylinder 102. One end of each linear tenon 104 is connected to the end of the lower cylinder 102 near the upper cylinder 101. Multiple linear tenons 105 are arranged in a circular array and fixedly connected to the end of the upper cylinder 101 near the lower cylinder 102. The outer wall of each linear tenon 105 is connected to the corresponding tenon. The linear tenon 104 is slidably connected inside. During the relative movement of the upper cylinder 101 and the lower cylinder 102, the linear tenon 105 will slide in the corresponding linear tenon 104. This can limit and guide the foam balls located in the ball storage cylinder 100, preventing the foam balls from squeezing the corrugated tube 103 and causing it to deform outward, thus affecting the stability of the feeding process. The combined use of the guiding mechanism and the corrugated tube 103 can not only wrap and shield the position between the upper cylinder 101 and the lower cylinder 102, but also limit and guide the foam balls during the feeding process, improving the stability of the foam balls feeding process.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
