| 摘 要： | 中海油渤海地区大部分油井已处于开发中后期,随着提高采收率压力的增大,很多老井需要注水、注聚合物等增产措施。由于层间矛盾较为突出、地质要求注水量大,原分注管柱不能满足油田分层注水的要求,开发了新型三层分层注水管柱,以渤海油田某井三层分注作业为例,介绍了作业流程、井下工具组合等。现场应用表明,该管柱施工成功率100%、配注合格率高,有效期长,是渤海油田实施三层分注的主要管柱。

| Abstract: | Most wells in CNOOC Bohai districts have been middle and late development periods.With enhanced pressure of recovery,there are many old wells need water injection,polymer injection and other measures to increase production.As the more prominent conflict between layers,big injection volume required by geology,and the original sub-injection stratified water column not meeting the requirements of oil field,a new type of three-layered water column has been developed.the processes,combinations and other downhole... |
