中原油田小井眼钻井技术实践

在中原油田应用开窗侧钻技术，达到了遏制井况恶化、挖掘剩余资源、节约投资、提高原油产量的目的。在小井眼开窗侧钻工艺中成功应用复合钻井技术，钻井速度提高了66％，选择合理的钻具组合可对井眼轨迹进行有效的控制。介绍了小井眼完井技术的技术要点，该技术的应用解决了固井质量低的难题，对小井眼微间隙钻井和完井具有一定的借鉴作用。

Practice on Slimhole Drilling Technology in Zhongyuan Oilfield

Sidetracking slimhole drilling technology is successfully to contain composite the well condition worsen ,trap the resource potential drilling is also successfully applied and the applied in Zhongyuan oilfield in order and increase the penetration rate.The drilling rate increases 66%.Reasonable BHA can effectively control the well trajectory.This paper introduces on the technical main points of slimhole completion technology.This technology application solves the problem about low quality cementing,which can provide some references for slimhole gap drilling and completion
