非均质油藏矢量化井网部署研究与应用效果

Research and application effect of vectorized well pattern deployment in heterogeneous reservoirs

A油田是一个典型河流相非均质油藏。油藏非均质性是影响该油藏水驱开发效果、剩余油分布的最根本原因。非均质性是该油藏未来开发效果的决定性影响因素。本文尝试通过矢量化井网部署优化弱化非均质性的影响,达到提高开发效果目的。本文开展岩性试验研究渗透率分布及差异性分析,将井网方向根据各向异性程度进行调整,该研究为类似油田开发提供了技术思路。

A oilfield is a typical heterogeneous reservoir. Reservoir heterogeneity is affected by the reservoir water flooding effect,the most fundamental reason for remaining oil distribution. Based on sedimentary microfacies and permeability distribution of research on the application of reservoir simulation technology Vector Well optimization,to weaken the negative impact of reservoir heterogeneity purposes. The study is similar oilfield development wells network deployment,adjustment and optimization studies provide technical ideas,have a very important role in guiding.
