Cause analysis and prevention measures for testing problems in deep inclined injection wells in Nanpu Beach Oilfield
In this paper,the research object is the deep inclined separate layer injection well in Nanpu beach.The in-depth analysis of the measurement and adjustment problem is carried out,and it is considered that the main influencing factors are the obstruction of the instrument and the difficulty of fishing.By optimizing the separate injection technology,high-pressure descaling technology and targeted prevention and control technology,the test success rate has increased to 84%,the operation construction has been greatly reduced,and the measurement and adjustment efficiency and economic benefits have been significantly improved.
