【摘要】：长庆油田今年在大规模部署水平井,布井数量大幅增多的情况下,结合区域开发地貌,布井方式及水平井开发工艺,设计实施工厂化水平井组。目前工厂化施工在长庆油田属重点发展项目,并大规模布置工厂化丛式三维水平井井组。通过近两年的不断摸索、实践、优化,施工效果表明:加快了施工速度,缩短了投产周期,满足了低成本开发需求,形成了具有该合作区特色的工厂化钻完井作业模式,实现了“三低”气田的规模效益开发,为气田高效开发树立了新样板。通过对工厂化三维水平井施工中应注意的一些问题进行探讨,需要预先计划施工顺序,达到防碰绕障的目的,同时,提前进行井眼剖面优化设计、井眼轨迹控制预防、钻井液性能维护等重点技术措施的论证及制定。达到安全快速施工三维水平井的目的。
[Abstract]:With the large-scale deployment of horizontal wells in Changqing Oilfield this year and the large increase in the number of well layouts, industrial horizontal well groups are designed and implemented with the combination of regional development landforms, well layout methods and horizontal well development techniques. At present, the factory construction in Changqing Oilfield is a key development project, and large-scale arrangement of factory cluster three-dimensional horizontal well groups. Through continuous exploration, practice, optimization and construction effect in the past two years, it is shown that the construction speed is quickened, the production cycle is shortened, the demand for low cost development is met, and the factory drilling and completion operation mode with the characteristics of the cooperation area is formed. The scale-benefit development of the three-low gas field is realized, which sets a new model for the high-efficiency development of the gas field. Through the discussion of some problems that should be paid attention to in the construction of three dimensional horizontal wells in factory, it is necessary to plan the construction sequence in advance to achieve the purpose of preventing collision and around obstacles. At the same time, the optimum design of borehole profile and the prevention of wellbore trajectory control are carried out ahead of time. Demonstration and formulation of key technical measures such as performance maintenance of drilling fluid. To achieve the goal of safe and fast construction of three-dimensional horizontal wells.
