摘要
Abstract
The Zhao 51 block of Sulige Gas Field is entering the middle and late stages of development.It is facing problems of formation energy attenuation,serious fluid accumulation in the wellbore,and high pressure at the wellhead,which restrict the release of gas well productivity.In order to reduce the back pressure at the wellhead and discharge fluid accumulation in the wellbore,the principles and characteristics of the integrated drainage and gas production technology of wellbore booster gas lift and wellhead pressure reduction were studied and analyzed,and seven wells in the Z51-12 well group were selected for field tests in the Zhao 51 block of Sulige Gas Field.The test results show that through the synergistic effect of"wellhead suction and pressure reduction+casing gas lift",the average daily gas production of the seven wells in the well group is 0.23 cubic meters,and the wellhead pressure can be reduced to as low as 0.22 MPa.Among them,well Z51-12 has changed from intermittent production to continuous production,and the production rate of the three intermittent production wells Z41-11C4,Z50-11,and Z41-11C2 has increased from 3.5%to 16.7%.This technology has shown good stimulation effect in cluster well groups in Zhao 51 block.This study provides reliable reference and practical basis for the management of liquid accumulation wells in the Sulige Gas Field and other similar blocks.关键词
