Field test of low-pressure gas-liquid mixed transportation and boosting technology in the Sulige gas field
摘要
Abstract
After more than 20 years production of Sulige gas field,formation pressure has generally decreased,gas well productivity has declined,and wellbore fluid-carrying capacity has gradually deteriorated.A large number of low-production gas wells and increasingly obvious liquid accumulation have seriously affected the effective performance of gas wells.Drainage gas production technology is currently the main method to address this issue,but it relies on the formation energy of the gas well itself and has certain limitations.Therefore,in order to effectively remove the wellbore fluid accumulation and resume normal production,this study analyzes the principles and characteristics of low-pressure gas-liquid mixed transportation and boosting technology.A field test was conducted on selected pilot wells using a wellhead skid-mounted gas-liquid mixed transportation and boosting device.The test device has been running for 44 days without failure,a cumulative gas increase of nearly27.6×104 m3,and an output-to-input ratio of more than 1.5.The test results are positive and demonstrated certain economic benefits.The result of field test indicates that the low-pressure gas-liquid mixed transportation and boosting technology is reliable and technically feasible,with stable device operation capable of timely and effectively removing wellbore liquid accumulation.The research results provide technical support for drainage gas production of low-production wells in the Sulige gas field.However,as the technology is still at the field test stage,further theoretical research and field validation are required.关键词
