渤海歧口17-2油田优快钻完井技术实践

总结渤海歧口 17- 2油田在开发过程中应用现代钻完井新技术和新工艺 ,在工程项目的进度、质量、安全、成本控制等方面都取得了优异的成绩。该项目面临的困难是油田地质条件比较复杂 ,同时油藏开发中面临用一座井口平台开发同一油田的 2个高点的难题。经过项目组的艰苦努力 ,应用渤海优快钻井完井技术 ,取得了 2 7口井用 15 2 .8d完成总进尺 5 9910m ,平均建井周期5 .6 6d的钻井好成绩。用 14 2 .2 4d完成 2 7口井的完井工作 (其中 8口注水井、19口生产井 ) ,平均单井砾石充填 2 .9层 ,取得平均单井完井周期 5 .2 7d的完井作业好成绩。在项目中还实现了 5项技术创新 :单筒双井钻井技术 ,大位移井钻井技术 ,水源井简化井身结构及配套钻井、固井技术 ,DTMZ防砂完井技术 ,钻完井储层保护技术。该项目在渤海的成功的实施 ,进一步拓展了渤海的优快钻完井技术 ,并且为今后边际油田的开发和建设 ,提供了成功的经验

Application of the Modern Optimized Fast Drilling in the QK 17-2 Oilfield in Bohai Sea

The paper introduces the modern optimized fast drilling, which was applied in the QK 17-2 oilfield in the Bohai Sea. With complicated structure complicated in geology, the oilfield was challenged to exploit two different areas with one wellhead platform. By application of the modern optimized fast drilling, the good results were achieved, drilling 27 wells in 152.8 days with total footage of 59910 m. By doing so, five new techniques were brought forth. The experience of drilling in the oilfield will be benefit for marginal well development in the future.
