摘要
为了解决L油田巨厚层油藏水淹规律复杂、剩余油分布预测难度大等问题,综合运用岩心、测井、录井及油藏动态等资料,对油藏储层非均质性成因及分布特征进行研究。研究结果表明:构造作用和成岩作用对L油田储层非均质性的影响较弱,储层非均质性主要受沉积作用的影响;油藏层内非均质性较弱,层间非均质性强,平面非均质性受沉积微相控制。
In view of the complexity of water-outlaw and the difficulty of predicting residual oil distribution in the giant thick reservoir of L oilfield,this paper studies the formation and distribution characteristics of reservoir heterogeneity based on the data of core,well logging,logging and reservoir performance. The results show that the effect of tectonism and diagenesis on the heterogeneity of the reservoir in L oilfield is weak and mainly affected by sedimentation. The reservoir is weak in intra-layer heterogeneity,strong in inter-layer heterogeneity,and the plane heterogeneity is controlled by sedimentary microfacies.
