摘要
套损侧钻井是根据特殊的地质特点,为了不改变原有井网而开发的一个新井种。这种井的技术要求高,难度大,它所要求的井眼轨迹需严格控制在技术指标范围内。介绍了该井型的技术原理、关键问题、解决途径,分别就施工中各阶段的技术要求进行分析,提出可行的操作要领,为油田套损井修井提供了新的方法。
The sidetrack drilling well is one kind of new well developed according to the special geological characteristics in order not to alter the original well pattern.The technical requirements for this kind of well are not easy to meet.The well track needs to be strictly limited in the technical descriptions.In this paper,the technical mechanics,key problems,and solution methods are introduced.The technical requirements for different operation stages are analyzed,and the feasible operation main points are established.The sidetrack drilling is one new method for the workover of casing damaged wells in oilfields.
