【摘要】：长北区块是中石油长庆油田的重点对外合作项目区块,也是长庆油田重要的天然气气藏勘探与开发区块。多年来,长北区块一直在探索高效经济的开发手段,其中二开定向段的施工成为最关键的攻关环节,对于区块整体双分支水平井的钻井技术理论研究具有重要意义,并能够进一步提升该区块水平井的优质高效勘探开发。针对长北区双分支水平井定向段钻井施工问题,本文通过优化井眼轨道设计结合高精度MWD随钻仪器提高对井眼轨迹的控制,并研究与水平井钻井技术相配套的安全钻井及提速技术,进一步优化相关技术与工艺,完善相关工具的配套,达到长北区块安全高效开发的目的,形成了系列技术成果与该区块水平井施工的标准模板,为长北区块后续二期、三期项目的安全、快速施工打下了良好的基础,提供了同类型井值得借鉴的设计与施工经验。
[Abstract]:Changbei block is a key foreign cooperation project block in CNPC Changqing Oilfield, and is also an important gas reservoir exploration and development block in Changqing Oilfield. For many years, Changbei block has been exploring efficient and economical development means, in which the construction of the second opening directional section has become the most critical link, which is of great significance to the theoretical study of drilling technology for the whole block with two branches horizontal wells. It can further improve the high-quality and high-efficient exploration and development of horizontal wells in this block. In order to solve the drilling problem of directional section of double-branch horizontal well in Changbei district, this paper improves the control of borehole trajectory by optimizing the design of borehole track and combining with high-precision MWD while drilling instrument. And the safety drilling and speed raising technology, which is matched with horizontal well drilling technology, is studied to further optimize the relevant technology and technology, to perfect the matching of relevant tools, and to achieve the purpose of safe and efficient development in Changbei block. A series of technical achievements and standard formwork for horizontal well construction in this block have been formed, which have laid a good foundation for the safe and rapid construction of the second and third phase projects in Changbei block, and provided the design and construction experience of the same type wells worthy of reference.
