Problems solved by technology

[0002] In the field of petrochemical industry, the auxiliary facilities of scattered single wells, remote wells, side exploration wells and evaluation wells in oilfields are poor, and they cannot be treated separately. , the gas volume is unstable, and the production cycle is short, so it is impossible to enter the oilfield surface gathering and transportation system for unified gathering and transportation. The natural gas produced by these single wells cannot be effectively recovered. In addition, the natural gas produced by conventional oil testing and gas testing devices is generally Burning on the spot not only wastes resources, but also causes environmental pollution

Embodiment 1

[0095] The gas coming from the wellhead is low-pressure gas (less than 7MPa). After being processed by the system of this application, the process of exporting it through the natural gas exporting pipeline is as follows:

[0096] When the pressure of the incoming gas from the wellhead is lower than the minimum allowable working pressure of the natural gas processing module 16 for molecular sieve adsorption and dehydration, and the second throttle valve 11 to throttle the temperature and remove hydrocarbons, it is necessary to pass the incoming gas from the wellhead through the separation and regulation of the separation and pressure regulation module 14. After processing the incoming gas from the wellhead to 0.1-0.35 MPa, it is connected to the first three stages (first, second and third stages) of the compressor assembly 15. The pressure is stepped up to 7.0-8.0 MPa, and the cooled gas leaves the compressor assembly and is connected to into the natural gas processing module 16...

Embodiment 2

[0099] The gas coming from the wellhead is low-pressure gas (less than 7MPa). After being processed by the system of this application, the process of transporting it outside by CNG tanker is as follows:

[0100] When the pressure of the incoming gas from the wellhead is lower than the minimum allowable working pressure of the natural gas processing module 16 for molecular sieve adsorption and dehydration, and the second throttle valve 11 to throttle the temperature and remove hydrocarbons, it is necessary to pass the incoming gas from the wellhead through the separation and regulation of the separation and pressure regulation module 14. After processing the incoming gas from the wellhead to 0.1-0.35 MPa, it is connected to the first three stages (first, second and third stages) of the compressor assembly 15. The pressure is stepped up to 7.0-8.0 MPa, and the cooled gas leaves the compressor assembly and is connected to into the natural gas processing module 16, and then enter t...

Embodiment 3

[0103] The gas coming from the wellhead is high-pressure gas (higher than 7MPa). After being processed by the system of this application, the process of exporting it through the natural gas exporting pipeline is as follows:

[0104] When the pressure of the incoming gas from the wellhead is higher than the minimum allowable working pressure of the natural gas processing module 16 for molecular sieve adsorption dehydration and the second throttle valve 11 for throttling to cool down and dehydrocarbonate, in order to prevent the inlet pressure from exceeding the upper limit of the corresponding container design pressure. Dangerous accidents, it is necessary to reduce the pressure of the high-pressure wellhead gas through the heating and throttling module 17, and treat the wellhead gas to 7.0-8.0MPa, and then remove the liquid through the separation and pressure regulation module 14, and then directly Connected to the natural gas processing module 16, after passing through the pre...

Abstract

The invention discloses an oil test, gas test and recycling integrated natural gas processing system, comprising a separating and pressure regulating module, a heating and throttling module, a compressor assembly, a natural gas processing module and a CNG (Compressed Natural Gas) filling module; an inlet end of the separating and pressure regulating module is connected with a first raw material gas pipeline while an outlet end of the separating and pressure regulating module is connected with an inlet end of the compressor assembly; a front three-stage pressurizing outlet end of the compressorassembly is connected with the natural gas processing module; an inlet end of the heating and throttling module is connected with a second raw material gas pipeline while an outlet end of the heatingand throttling module is connected with the separating and pressure regulating module; an outlet end of the natural gas processing module is connected with a natural gas transportation pipeline and further connected with a rear three-stage pressurizing inlet end of the compressor assembly. The natural gas processing system provided by the invention can integrate the modules with different functions in a pry seat highly; the device can be arranged in a flat car to be transported to the field, and then the device is directly arranged in the well site to run.

Description

technical field [0001] The invention relates to the technical field of natural gas processing, in particular to a natural gas processing system integrating oil testing, gas testing and recovery. Background technique [0002] In the field of petrochemical industry, the auxiliary facilities of scattered single wells, remote wells, side exploration wells and evaluation wells in oilfields are poor, and they cannot be treated separately. , the gas volume is unstable, and the production cycle is short, so it is impossible to enter the oilfield surface gathering and transportation system for unified gathering and transportation. The natural gas produced by these single wells cannot be effectively recovered. In addition, the natural gas produced by conventional oil testing and gas testing devices is generally Using the form of burning on the spot not only wastes resources, but also causes environmental pollution.
