七棵树油田开发特征分析

摘要

七棵树油田属于低渗透构造-岩性油藏，储层为常温、异常低压系统，原油粘度低，地饱压差小，含蜡高，气油比高。油田开发层系简单，主力油层为沙河子组2、3号砂体。文章主要分析了开发过程中呈现的开发特征，为油田下步稳产高产的调整方向提供参考。%The Qikeshu Oilfield belonging to the low permeability structure-lithology reservoir, the reservoir is at room temperature, abnormal low pressure system, low viscosity of crude oil, small formation-saturation pressure difference, high waxy and gas-oil ration. Department of oilfield development layer is simple, the major reservoirs are only the No.2 and No.3 sand body of Shahezi. The paper analyzed the development characteristics presented in the development process, and provided references for the next step adjustment measure.
