生产尾管固井技术优化及其在渤中25-1油田中深丛式井的应用

渤中25-1油田沙河街组油藏属于中深层高温高压油藏,制约了常规尾管固井技术的应用。对生产尾管固井技术进行了优化,解决了中深丛式井生产尾管固井作业安全、质量与时效之间的矛盾,实现了非钻机时间候凝和电测固井质量,显著提高了钻井作业时效。该项技术成果对于渤海中深层油田的开发具有重要意义。

Production liner cementing technique optimization and its application in mid-depth cluster wells of BZ25-1 oilfield

The Shahejie formation reservoir of BZ25-1 oilfield is the mid-depth high temperature and pressure reservoir,which restraints the application of convention liner cementing technique.Through the optimization of production liner cementing technique,the contradiction among safety,quality and time efficiency during production liner cementing operation of mid-depth cluster wells was resolved.Waiting on cement out of rig time and electrical logging cement quality were achieved and drilling time efficiency was raised obviously.This technique has an important significance in developing mid-depth oilfield in Bohai Sea.
