鱼骨水平井在高效开发边台潜山中的应用

边台潜山属于低孔低渗透的裂缝性油气藏,并且在纵向上的层位厚度不均,裂缝发育差,属于难动用油藏。通过应用多分支鱼骨水平井技术,明显提高了开发效果。以一口上下双层分支、每分支带鱼骨的井为例,系统论述了鱼骨水平井设计依据,施工关键技术及开发效果,为今后开发此类难动用油气藏提供了借鉴。

Application of Fishbone Horizontal Well to the Efficient Exploration of Bian Tai Qian Shan

Bian Tai Qian Shan belongs to the fractural hydrocarbon reservoir with lower porosity and low permeability.In vertical dimension,the thickness of its reservoir rock is uneven,and the development of its fracture is very poor.So it is the reservoir rock difficult to open up.Through the use of technology about fishbone horizontal well with multiple branches,the developing effect has been improved greatly.In this paper,one well with branches of up and down layers is taken as an example,each branch of which has the fishbone.The paper systematically explains the design basis,the key techniques of construction,and the developing effect of fishbone horizontal wells,and provides some references for the development of this similar kind of hydrocarbon reservoir.
