At 18 o'clock in the afternoon of July 9th, two CHB2 high-pressure gas lift compressor units independently developed by Himile successfully passed the 72-hour trial operation performance test on the 75 and 58 platforms of Sichuan shale gas respectively, and successfully realized "one machine and three lifts"!

Q1 What is Gas Lift?

It is one of the important technological measures to improve the production of natural gas wells. By injecting gas into the formation, the liquid in the well is discharged, which solves the phenomenon of "water sealing and water blockage" in the formation and improves the gas production of the gas well.

Q2 What is "one machine and three achievements"?

One compressor can meet the gas lift operation of one to three wells at the same time, and realize the synchronous gas lift of multiple wells through intelligent distribution of gas volume, reduce the configuration of gas lift equipment, and improve the utilization rate of equipment.

With the continuous exploitation of shale gas, the production pressure and production capacity of the wellhead will gradually decrease, the amount of gas lift operation will continue to increase, and the cost of final well technology measures will continue to increase.

"Focus on customers’ needs, improve ourselves persistently". In the face of the current situation, Himile carried out a large number of shale gas well condition data and process analysis, and finally "tailored" two compressor packages for the customer, CHB2 and CHB4.

The power of the body of the two units is 300kW and 600kW respectively, and the rated speed is 1800r/min, which can be applied to continuous gas lift, high-pressure gas lift, wellhead pressurization, single well and multi-well platform pressurized gas lift integration and other working conditions. At the same time, according to the actual production needs, the gas lift of a single well can be freely allocated to fully meet the needs of multiple wells at the same time.

At present, the CHB2 unit has been successfully put into operation, and compared with the original compressor unit of the platform, its pressure range is wider, the working condition adaptability is stronger, the operating cost is lower, and the operation cycle is longer. At the same time, the whole skid also has many advantages such as compact structure, low noise, low vibration, automation and high degree of intelligence.

The successful implementation of "one machine and three achievements" of Himile compressor units not only helped the customer to effectively control the production cost of shale gas exploration and development, but also marked the official entry of Himile into the field of shale gas lift boosting with its own brand.

In the future, Himile will continue to provide customers with "one-stop service" to help the development of clean energy in China!
