【摘要】：丛式井组井工厂钻井技术能够节约井场占地面积,提高钻井效率,降低开发成本。该技术主要应用于页岩气的开发,目前也是致密性油藏和低渗透油藏实施规模开发的有效途径。白鹭湖区块处于风景区内,井场面积受限,环保要求严格,借鉴国内外丛式井组井工厂的施工经验,在油藏地质研究的基础上,实施了白鹭湖大型丛式井井工厂项目,通过钻井方案整体优化、井工厂优快钻井技术配套以及钻井液体系优选,顺利完成了43口井的钻井施工,大幅提高了机械钻速,有效缩短了钻井周期,降低了钻井成本。实践证明,大型丛式井井工厂钻井技术为低渗透油藏高效开发提供了技术支持。
[Abstract]:The drilling technology can save the area of the well site, improve the drilling efficiency and reduce the development cost.This technology is mainly used in shale gas development and is also an effective way to implement scale development in dense reservoirs and low permeability reservoirs.The block of Bailu Lake is located in the scenic area, the well site area is limited, and the environmental protection requirements are strict. Based on the reservoir geological research, the project of large cluster well well factory in Bailuhu Lake has been implemented on the basis of the construction experience of the group well factory at home and abroad.The drilling operation of 43 wells has been successfully completed through the overall optimization of drilling scheme, the matching of high speed drilling technology in well factories and the optimization of drilling fluid system. The drilling speed of 43 wells has been improved greatly, the drilling cycle has been effectively shortened and the drilling cost has been reduced.It is proved by practice that drilling technology in large cluster well factory provides technical support for high efficiency development of low permeability reservoir.
