Embodiment 1

[0029] Such as Figure 1~4 As shown, the wellhead pressurized reciprocating natural gas compressor unit includes a skid-mounted noise reduction room 21, and the noise reduction room 21 is equipped with a compression separation cooling assembly, which is connected in series between the production pipeline and the storage pipeline. The intake pipeline 3 in the cooling assembly communicates with the production pipeline, the exhaust pipeline 1 communicates with the storage pipeline, and the pipeline connected between the intake pipeline 3 and the exhaust pipeline 1 is provided with a first-stage separator 5 and a first-stage compression cylinder connected in sequence 7. The secondary air cooler 14, the secondary separator 10, the secondary compression cylinder 12, the secondary air cooler 14 and the tertiary separator 15;

[0030] There is also a PLC control cabinet 19 and a power distribution box 20. The PLC control cabinet 19 is used to collect the pressure, temperature, separat...

Embodiment 2

[0043] Further illustrate in conjunction with embodiment 1, as Figure 1~4 As shown, the present invention designs a skid-mounted noise reduction room 21, a separator adapted to the wellhead gas, a reciprocating compressor host adapted to pressure and flow fluctuations, a process gas pipeline, a lubricating oil system, a venting system, a sound insulation room, The PLC control system and the sound and light alarm system realize the quick movement and quick installation of the unit, the allocation of gas volume at different wellheads, and the unattended unit. The technical solution of this invention takes the four-cylinder two-stage piston compression design as an example. The main engine of the reciprocating compressor adopts a completely symmetrical and balanced structure. Meet the needs of the unit to adapt to changes in wellhead pressure and gas volume. The unit adopts a skid-mounted noise reduction room 21. The sound insulation cover is installed on the base and is sealed...

Abstract

The invention provides a wellhead pressurization reciprocating type natural gas compressor unit, comprising an integrated base, a separator adapting to wellhead gas quality, a reciprocating type compressor main machine adapting to pressure and flow fluctuation, a process gas pipeline, a lubricating oil system, an emptying system, a sound insulation room, a PLC control system, a sound-light alarm system, and the like. The unit is low in weight, compact in size and structure, free of foundation installation, and capable of implementing rapid installation, moving and debugging; and the gas flow of different wellheads is adapted by adjusting the number of the units. Each stage of gas inlet valve is provided with an unloader to implement single-action and double-action switching of compression of different stages of cylinders, so that the requirements of the unit for adapting to wellhead pressure and gas quantity changes are met. According to the wellhead pressurization reciprocating type natural gas compressor unit, the problems of large investment, high operation and maintenance cost and high environmental protection requirement of shale gas extraction, collection and transportation equipment are solved, and unattended operation and stable long-period operation of wellhead equipment are achieved.

Description

technical field [0001] The invention relates to the field of shale gas exploitation, in particular to a wellhead pressurized reciprocating natural gas compressor unit. Background technique [0002] The reciprocating natural gas compressor is a machine used to compress gas to increase the gas pressure. It is mainly used in the fields of trial gas recovery, wellhead gas collection and treatment, gas lift gas recovery and oil recovery, pressurized transportation and other fields. At present, large-scale shale gas exploitation is being carried out in Fuling and Nanchuan areas. Most of the gas wells are built in mountainous areas. The distance span between different gas wells is large, and the workload of transportation, installation, operation and maintenance is heavy, and there are differences in gas volume and pressure between wellheads in different areas. There is a large difference, and in order to protect the mountainous environment, the requirements for environmental prote...
