针对胡状集油田由于层间非均质性严重造成小层水驱动用不均、水驱采收率低的突出矛盾,项目围绕重组细分开发层系开展了一系列的攻关技术研究,提出了多项技术创新,确定了层系内渗透率级差小于6倍、小层启动压差小于6MPa为核心的重组细分技术界限,形成了一套严重非均质油藏重组细分的开发技术序列。
Aiming at the obvious contradiction between the uneven distribution of driving water and the low waterflood recovery in the Huzhuangji oilfield due to the heterogeneity in the interlayer, the project carried out a series of researches on the key points of the reorganization and subdivision development strata, A number of technological innovations were identified, the boundaries of reorganized subdivision with permeation rate difference less than 6 times within the stratigraphy layer and small pressure difference under 6 MPa as the core were determined, and a set of development technologies for the reorganization and subdivision of serious heterogeneous reservoirs was formed sequence.
