AI Technical Summary

Technical Problem

In existing technologies, the power difference between compressor units in booster gas extraction mode and gas lift mode is significant, making it difficult to use a single compressor unit universally, resulting in high purchase and operating costs.

Method used

Design an integrated compressor that can switch between online boosting and gas lift. By combining control valves and separators, the compressor can flexibly switch between boosting gas intake and gas lift liquid discharge. A combination of a four-stage boosting and separation structure and control valves is adopted to enable the compressor to be used in different operating conditions.

Benefits of technology

It enables the sharing of compressors under different operating conditions, reduces purchase and operating costs, simplifies the equipment replacement process, and improves equipment utilization.

Abstract

The application discloses an online switching pressurization and gas lift integrated machine, which comprises an air inlet separator, a first-stage pressurization separation mechanism, a second-stage pressurization separation mechanism, a third-stage pressurization separation mechanism, a fourth-stage pressurization separation mechanism and a control valve, wherein one end of the air inlet pipeline is connected with an air inlet end of the air inlet separator; an air outlet end of the air inlet separator is connected with an air inlet end of the first-stage pressurization separation mechanism; an air outlet section of the first-stage pressurization separation mechanism is connected with an air inlet end of the second-stage pressurization separation mechanism; an air outlet end of the second-stage pressurization separation mechanism is connected with an air inlet end of the third-stage pressurization separation mechanism; an air outlet end of the third-stage pressurization separation mechanism is connected with an air inlet end of the fourth-stage pressurization separation mechanism; and an air outlet end of the fourth-stage pressurization separation mechanism is connected with an air outlet pipeline. The application realizes two functions with one machine, and realizes online switching of pressurization and gas lift operation conditions, so that the problem that the power of the compressor set is too different between the pressurization gas recovery condition and the gas lift condition and a single set of compressors is difficult to be used universally is solved.
