Description

Technical Field

[0001] This utility model belongs to the technical field of high-efficiency gathering and transportation devices for shale gas well production sites, specifically relating to a high-efficiency gathering and transportation device for shale gas well production sites. Background Technology

[0002] The high-efficiency shale gas gathering and transportation system is a modular system integrating multiple functions such as gas gathering, separation, pressurization, metering, purification, and transportation. It is specifically designed for the characteristics of shale gas extraction. It can centrally collect sand-bearing and liquid-bearing natural gas produced from multiple dispersed shale gas wells, remove impurities such as moisture, dust, and heavy hydrocarbons through a high-efficiency separator, and then pressurize it to the transportation pressure through a compressor unit. Combined with an intelligent metering and monitoring system, it can achieve precise control of gas volume and finally stably transport qualified shale gas to the gathering and transportation pipeline network or processing plant. This system is adapted to the characteristics of large fluctuations in shale gas production and rapid changes in wellhead pressure. Through modular design, it can be quickly deployed, and at the same time, it can reduce energy consumption by using energy-saving technology, thereby improving the efficiency and economy of shale gas gathering and transportation.

[0003] When using high-efficiency gathering and transportation equipment for shale gas well production sites, the tanks are too heavy and need to be placed in designated locations using a crane. Furthermore, if the inlet and outlet are not facing the installation area during placement, repeated adjustments are required, making the operation too cumbersome. Therefore, the market needs a new device to solve the current problems. Utility Model Content

[0004] The purpose of this utility model is to provide a high-efficiency gathering and transportation device for shale gas well production sites, in order to solve the problem that the high-efficiency gathering and transportation device for shale gas well production sites proposed in the background art has excessive weight of the tank, which requires a crane to place it in a designated location. Furthermore, if the air inlet and outlet are not facing the installation area during placement, repeated adjustments are required, which is too cumbersome. Therefore, the market needs a new device to solve the current problems.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-efficiency gathering and transportation device for shale gas well production sites, comprising an outer tank, an outlet at the lower left end of the outer tank, an inlet at the upper right end of the outer tank, multiple support columns fixed at the lower end of the outer tank, a T-shaped rod fixed at the lower end of each support column, multiple ball bearings sleeved inside the T-shaped rod, a threaded hole at the lower end of the T-shaped rod, a support frame at the lower end of each support column, multiple sliding grooves inside the support frame, the T-shaped rod sleeved inside the sliding grooves, a stainless steel bolt inserted into the lower end of each sliding groove, the stainless steel bolt passing through the sliding groove and entering the threaded hole, an aerogel felt insulation layer inside the outer tank, and an inner tank inside the aerogel felt insulation layer.

[0006] Preferably, a nameplate is provided at the middle position of the front end of the outer tank, and a pressure gauge is provided at the lower middle position of the front end of the outer tank.

[0007] Preferably, a safety valve is provided at the upper end of the outer tank, and a drain valve is provided at the lower end of the outer tank.

[0008] Preferably, the drain valve discharges impurities accumulated inside the tank, such as oil and condensate carried by the gas.

[0009] Preferably, a flange is provided at the front end of both the air outlet and the air inlet, and the air outlet and the air inlet lead to the inner tank.

[0010] Preferably, the support frame supports the outer tank, and the T-shaped rod and the ball bearing are located inside the groove.

[0011] Preferably, the support column can move along the slide groove via a T-shaped rod and ball bearings, and the movement of the support column causes the outer tank to rotate.

[0012] Preferably, the stainless steel bolt enters the threaded hole from the lower end of the groove, so that the support column remains in a fixed position.

[0013] Compared with the prior art, this utility model provides a high-efficiency gathering and transportation device for shale gas well production sites, which has the following beneficial effects:

[0014] 1. This device supports the tank body with a support frame. When adjusting the tank body, the outer tank body is rotated by moving the support column. When the support column moves, the T-shaped rod and ball bearings move at the inner wall of the slide groove. In this way, the outer tank body is rotated so that the air inlet and outlet face the installation position. The position of the tank body is fixed by inserting stainless steel bolts into the threaded holes. This method facilitates the adjustment of the tank body and increases the flexibility of use.

[0015] 2. This device has two tanks. The inner tank ensures gas sealing and pressure bearing. The middle aerogel felt insulation layer reduces the heat exchange between the inside and outside of the tank through high-efficiency heat insulation, suppresses the thermal expansion and contraction of the gas caused by changes in ambient temperature, and keeps the pressure fluctuation within a controlled range, greatly improving the operational stability of downstream equipment such as compressors and meters. The outer tank, through mechanical protection and structural support, protects the insulation layer from external damage and controls the surface temperature of the tank within the ambient temperature range, eliminating the risk of burns or frostbite to operators.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] In the description of this utility model, it should be noted that the terms "upper," "lower," "inner," "outer," "front end," "rear end," "both ends," "one end," and "the other end," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] The utility model provides, for example Figure 1-4 The diagram shows a high-efficiency gathering and transportation device for a shale gas well production field, comprising an outer tank 1, an outlet 10 located at the lower left end of the outer tank 1, an inlet 11 located at the upper right end of the outer tank 1, multiple support columns 9 fixed at the lower end of the outer tank 1, a T-shaped rod 15 fixed at the lower end of the support column 9, multiple ball bearings 16 sleeved inside the T-shaped rod 15, a threaded hole 14 located at the lower end of the T-shaped rod 15, a support frame 7 located at the lower end of the support column 9, multiple sliding grooves 5 located inside the support frame 7, the T-shaped rod 15 sleeved inside the sliding grooves 5, a stainless steel bolt 6 inserted into the lower end of the sliding groove 5, the stainless steel bolt 6 passing through the sliding groove 5 and entering the threaded hole 14, an aerogel felt insulation layer 13 located inside the outer tank 1, and an inner tank 12 located inside the aerogel felt insulation layer 13.

[0025] The inlet 11 and outlet 10 are connected to the transmission pipeline. Shale gas extracted from shale gas wells is initially collected by the wellhead gathering and transmission pipeline network and then enters the buffer tank through the inlet 11. Due to the influence of factors such as changes in formation pressure and multi-well collaborative gas production, the gas volume and pressure of shale gas wells fluctuate. The tank, with its large volume, provides temporary storage and buffer space for shale gas. Pressure gauge 4 provides feedback on the pressure data inside the tank. The operation and maintenance personnel of the gathering and transmission system can use the data to accurately control the pressure and gas flow inside the tank by adjusting the valves on the inlet and outlet pipelines. After the shale gas is buffered and the pressure tends to stabilize inside the tank, it is orderly transported to downstream gas purification devices, pressurization equipment and other links through the outlet 10. At the same time, a small amount of liquid impurities such as condensate and oil carried in the shale gas will settle to the bottom of the tank under the action of gravity and can be discharged periodically through the drain valve 8 to prevent these impurities from entering downstream equipment and affecting the gathering and transmission efficiency and equipment life.

[0026] like Figure 1 and Figure 4 As shown, a nameplate 3 is installed at the middle position of the front end of the outer tank 1. A pressure gauge 4 is installed at the lower middle position of the front end of the outer tank 1. A safety valve 2 is installed at the upper end of the outer tank 1. A drain valve 8 is installed at the lower end of the outer tank 1. The drain valve 8 discharges impurities accumulated inside the tank, such as oil and condensate carried by the gas. Flanges are installed at the front ends of the air outlet 10 and the air inlet 11. The air outlet 10 and the air inlet 11 lead to the inner tank 12. The support frame 7 supports the outer tank 1. The T-shaped rod 15 and the ball bearing 16 are located inside the slide groove 5. The support column 9 can move along the slide groove 5 through the T-shaped rod 15 and the ball bearing 16. The movement of the support column 9 causes the outer tank 1 to rotate. The stainless steel bolt 6 enters the threaded hole 14 from the lower end of the slide groove 5, so that the support column 9 remains in a fixed position.

[0027] By moving the support column 9, the outer tank 1 is rotated. When the support column 9 moves, the T-shaped rod 15 and the ball bearing 16 move at the inner wall of the slide groove 5. In this way, the outer tank 1 is rotated, and the air inlet 11 and the air outlet 10 are oriented toward the installation position. The position of the tank is fixed by inserting the stainless steel bolt 6 into the threaded hole 14.

[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.
