Exploration of Process Technology and Supervision Mode to Reduce the Work-load of Abnormal High-Pressure Wells with Pressure Operation in Old Oil Fields
In view of the current situation that the workload of abnormally high pressure wells with pressure increases geometrically in old oil fields,in order to control the increment of pressure operation in abnormal high-pressure wells,reduce the cost of pressure op-eration,improve the construction quality of pressure operation,and reduce the risk of pressure operation,through combing the prob-lems existing in the process of technical management of pressure operation,the seven specific measures were established,including the formation of the management system of pressure operation,the establishment of the management responsibilities of pressure opera-tion,the accurate verification of the wellhead pressure before pressure operation,the improvement of the design of pressure engineer-ing,the application of blowout prev tools in casing,and the strengthening of risk identification and on-site supervision and manage-ment,achieving good results,namely,the annual workload with pressure being decreased by 13.8%,the proportion with pressure be-ing reduced by 30.7%,and the cost of pressure being saved by 9.72 million yuan.In a word,remarkable results have been achieved in reducing the workload of abnormal high-pressure wells with pressure.
