Abstract: The MA18 block of Xinjiang oil field belongs to lowpermeability reservoir, whose pressure sensibility is medium to strong. Fracture is adopted to develop this block. The effect of fracture was simulated by diamondshaped inversed 9 point pattern using Eclipse. The threshold pressure gradient and the voltagesensitive effect were taken into consideration in this pattern. Considering the position diversity of edge well,corner well and central well in the field of seepage flow, the different length of fracture was simulated In this way, the optimum parameters of the fracture were obtained. Finally, the regression relation of the fracturing effect and the fracture parameters acquired by the simulation of FracproPT were got which could guide the construction of optimal project efficiently.

Key words: Orthogonal design, Low permeability reservoir, Unequal fracture length, Numerical simulation, Regression relation

摘要: 新疆油田玛18井区属于低孔特低渗油藏,压力敏感中等偏强,需采取压裂方式进行开采。在充分考虑研究区块启动压力梯度及压敏效应的基础上,应用Eclipse软件建立菱形反九点井网模型模拟压裂效果。考虑到边井、角井、中心井在渗流场中的位置差异,进行不等缝长压裂效果模拟,得到最佳的裂缝参数组合形式;利用FracproPT模拟区块的压裂效果,得到裂缝参数与压裂参数的回归关系,从而得出最佳的施工方案。

关键词: 正交设计, 低渗透油藏, 不等缝长, 数值模拟, 回归关系
