Module structure for supercharging of gas field supercharging station

Abstract

The invention belongs to the technical field of the natural gas industry, and particularly provides a module structure for supercharging of a gas field supercharging station. The module structure comprises a gas inlet, a gas inlet pipeline, a gas inlet valve, a natural gas compressor, a gas outlet valve, a gas outlet and a gas outlet pipeline. The gas inlet and the gas inlet valve are connected with an inlet of the natural gas compressor through an inlet gas pipeline in sequence, and an outlet of the natural gas compressor is connected with the gas outlet valve and the gas outlet through a gasoutlet pipeline in sequence. The problem of long period due to the adoption of the single conventional construction mode for the surface gathering technology in the South area of the Yulin gas fieldin the prior art is solved. The module structure has the advantages of short construction period, compact structure and complete function, and has the functions of supercharging, emptying, separation,pollution discharge and the like.

Description

technical field

[0001] The invention belongs to the technical field of the natural gas industry, and in particular relates to a modular structure for supercharging a gas field supercharging station. Background technique

[0002] As the hub of China's natural gas pipeline network, Changqing Gas Field bears huge social and political responsibilities. In order to ensure the important role of natural gas production, storage, adjustment and emergency response in the hub center, the southern area of ​​Yulin Gas Field urgently needs to implement pressurized mining. At the same time, the southern area of ​​Yulin Gas Field is one of the important gas fields that guarantee the continuous and stable production of 50 million tons of Changqing Oilfield. It is the main gas source of the Shaanxi-Beijing system and a strong support for stable gas supply.

[0003] The southern part of the Yulin gas field started trial production in 2001. After nearly 20 years of development and construction,...

Examples

Embodiment 1

[0023] Such as figure 1 As shown, a modular structure for supercharging of a gas field supercharging station includes an air inlet 1, an air inlet pipeline 18, an air inlet valve 5, a natural gas compressor 15, an air outlet valve 8, an air outlet 2 and an air outlet pipeline 19, and the air inlet The port 1 and the inlet valve 5 are connected to the inlet of the natural gas compressor 15 through the inlet pipeline 18 in turn, and the outlet of the natural gas compressor 15 is connected to the gas outlet valve 8 and the gas outlet 2 through the gas outlet pipeline 19 in sequence.

[0024] The gas coming from the pigging area in the pressurization station passes through the inlet 1, and enters the natural gas compressor 15 through the inlet pipeline 18 through the inlet valve 5 for pressurization. After the pressurization, the natural gas enters the downstream process of the station through the outlet valve 8 and the outlet 2; It realizes pressurization function, compact struct...

Embodiment 2

[0026] On the basis of Embodiment 1, a balance valve 6 is further included, and the balance valve 6 and the intake valve 5 are connected in parallel through pipelines. The balance valve 6 adjusts the pressure balance before the intake valve 5 and the valve group during intake air, so as to improve the safety of pipeline equipment.

[0027] Further, a gas outlet check valve 7 is also included, and the gas outlet check valve 7 is connected to the gas outlet pipeline 19 between the natural gas compressor 15 and the gas outlet valve 8 . The air outlet check valve 7 prevents the backflow of the air outlet, plays the role of safety isolation, and prevents accidents from happening.

[0028] Further, it also includes a safety vent valve group 9, a vent pipeline 16 and a vent port 3, one end of the safety vent valve group 9 is connected to the intake line 18 between the intake valve 5 and the natural gas compressor 15, and the safety vent valve group The other end of 9 is connected to...
