"The maximum daily gas processing volume is 55,000 cubic meters, and the maximum daily liquid processing volume exceeds 200 cubic meters. The annual economic benefits amount to 4.53 million yuan." On September 6th, Luo Hu, the service personnel from the Chengdu Compressor Branch Company, introduced, "The first liquid-driven compressor for gas-liquid mixed transportation independently developed by the company was officially put into operation at the Yangta 1 Booster Station in the Tarim Oilfield. All indicators have met the design requirements, marking an important breakthrough in domestic high-end oil and gas mixed transportation equipment."
This unit has the ability to adaptively mix and transport gas and liquid in a full range of 0-100%. It effectively addresses the existing problems of poor filtration, short lifespan of vulnerable parts, and low pressure difference of the equipment in the oilfield. During the research process, the company jointly conducted key technology research on hydraulic reciprocating mixed transportation pressurization equipment with Xi'an Jiaotong University and Tarim Oilfield. They successively overcame 6 key technologies such as the calculation of multi-phase flow conditions for gas-liquid mixed transportation using liquid drive compressors, and innovatively formed a set of liquid drive compressors for gas-liquid mixed transportation products.
"This equipment not only simplifies the process flow but also enhances the gathering and transportation efficiency."
Zheng Baojun, a staff member at the Yangta 1 booster station in Tarim, said that the liquid-driven compressor unit for gas-liquid mixed transportation is driven by hydraulic power, operates with long strokes and low frequencies, without oil lubrication, and can adapt to the intake and exhaust pressures. It has the advantages of fewer transmission components, fewer wear parts, less maintenance workload, and ease of relocation. It is highly controllable and can achieve unmanned operation.
The successful application of this product is of great significance for enhancing the recovery rate of old wells and inefficient wells, promoting the recovery of wellhead gas and the mixed transportation of oil and gas, and achieving cost reduction and efficiency improvement in the oilfield.
