摘要/Abstract

摘要： 作为能有效解决低丰度、小型或者边际油气田经济性开采问题的关键技术,小井眼单通道井钻完井技术采用小的井眼尺寸、简化的井身结构及生产管柱设计,完井作业不占用钻机时间,能够最大限度降低钻完井过程中材料、机时等主要费用。目前该项技术已被国外几大石油公司广泛应用于全球多个地区,取得可观的经济效益,使许多低产断块油气田得以经济开发。同时,国外也有利用该技术成功开发煤层气、页岩气等非常规能源的先例。在我国,该项技术仅在少数几个陆地油田应用过,对于海上,部分油田采用了小井眼侧钻工艺,但单通道完井技术还未有应用的先例。因此开展单通道井钻完井关键技术的研究并推进相关技术的应用,对于降低海上边际油田开发费用、提高开发效益、为开发非常规能源提供技术储备均具有非常重要的意义。文章对单通道井钻完井技术中的原理、现状、钻井、完井及测试等关键技术进行了较详细的概括分析,并根据目前海上油气田取得的一些关键研究成果,提出了相关技术的解决方案,对今后指导该技术的推广应用具有一定的指导意义。

Abstract: As the key technology which can solve the economic exploitation problem of low-abundance, small or marginal oilfields, the slim-hole monobore drilling & completion technology using small borehole, simplified casing programs and production strings designs could reduce the use of material and rig time as much as possible. Many international oil companies have applied it in many oil & gas fields and exploited many low-yield fault-block oilfields economically. Unconventional energy such as CBM and shale gas could also be efficiently exploited by this technology according to some project cases abroad. It has been used in a few onshore oilfields and sidetrack drilling in some offshore oilfields in China. So research work and field application about monobore wells could reduce the cost of exploitation of low-abundance & offshore marginal oilfields, and supply a technical storage for unconventional energy exploitation. Key technologies of monobore were analyzed in this paper, and many solutions were also supplied according to study results in offshore oilfields. The analyzed technologies and solutions are of strong significance to the improvement and application of monobore technology.
