【摘要】：在油气资源日益紧张的今天,丛式井钻井技术的应用不但可以降低搬迁作业费用,还可以有效的提升低效油气井的开采率。随着海上油气田、低渗透油气田和老油气田的加密开采,丛式井在钻井领域的应用越来越广泛。由于在施工过程中相邻井之间的实钻轨迹距离很近,如果设计不合理,可能会导致非常严重的工程事故。因此,深入的研究探讨丛式井防碰绕障问题十分必要,对减少工程事故、节省钻井成本有着重要作用。根据不同的井深结构,选用合理的防碰扫描计算方法,确定出扫描参数并应用防碰扫描软件绘制出防碰图,从而可以确定出邻井与正钻井之间的最短距离,以确定有无碰撞的危险,进而制定出合理的预防措施。防碰工作贯穿于钻井周期的各个时期,为了提高钻井丛式井的防碰绕障成功率,降低钻井施工难度及钻井总成本,必须对钻井工程设计进行整体优化丛式井。本文主要是通过探讨丛式井轨道参数优化方法,从选择造斜点、造斜率、轨道类型等方面出发,全面布局,逐一优化,最终达到提高丛式井绕障成功率的目的。
[Abstract]:With the increasingly tense oil and gas resources, the application of the cluster well drilling technology can not only reduce the cost of the relocation operation, but also effectively improve the efficiency of the low efficiency oil and gas wells. With the encryption mining of the offshore oil and gas fields, the low permeability oil and gas fields and the old oil and gas fields, the application of the cluster wells is becoming more and more extensive in the field of drilling. The actual drilling path between the adjacent wells is very close. If the design is not reasonable, it may lead to very serious engineering accidents. Therefore, it is very necessary to study the problem of collision avoidance in the bushes well, and it is important to reduce the engineering accident and save the cost of drilling. Methods to determine the scanning parameters and use anti collision scanning software to draw a collision prevention map, which can determine the shortest distance between the adjacent well and the positive drilling, so as to determine the risk of collision, and then formulate a reasonable preventive measure. The anti collision work runs through the period of the drilling cycle, in order to improve the anti collision barrier formation of the drilling bushes. In order to reduce the difficulty of drilling and the total cost of drilling, the overall optimization of the well drilling engineering design must be optimized. This paper is mainly through the discussion of the optimization method of the track parameters of the cluster well, from the aspects of selecting the slanting point, the slope rate, the track type and so on, the overall layout and the optimization, finally, the goal of improving the success rate of the bush type well winding barrier is achieved. Yes.
