摘要： 鱼骨刺井作为新井型一出现就以其高产特性引起人们极大关注,其在油气田开发中的合理井网布置是鱼骨刺井应用的一个非常重要方面。采用数值模拟软件,以井网微单元的形式,对鱼骨刺井与直井组合的均匀布井方式进行数值模拟研究,分析了鱼骨刺井不同井型、分支角度、分支长度、分支位置对开发造成的影响,以及五点法、七点法、九点法等不同井网对开发效果的影响,提出了均匀井网中鱼骨刺井分支方位、角度和位置的优选方法,以及井网中注水井布井方位的选取办法,对于指导油田鱼骨刺井布井设计有重要意义。

Abstract: As a new well type, appearance of fish-bone well is now considerable concern for its high productivity nature. Its proper well placement is a crucial aspect in such a well application for oil-gas field development. With numerical simulation software, the uniform pattern of spacing for combination of fish-bone well with vertical well is numerically simulated. The influences of variety of fish-bone well types, branch angles, branch length, branch location on productivity, as well as the effects of different well patterns (five-spot, seven-spot and nine-spot patterns, etc.) on production performance are analyzed. This paper presents the selected principles for optimum branch orientation, angle and location of fish-bone well placement, and also, the selected method for injector placement orientation in these well patterns, which could be as a guide for design of such a well placement.

Key words: fish-bone well, well pattern, numerical simulation, feature
