王场油田盐间非砂岩油藏开采规律和挖潜对策

Production Laws of Non-sandstone Oil Accumulations between Salt Layers and Strategy to Tap Its Potential in Wangchang Oilfield

江汉盆地王场油田盐间非砂岩油藏为中低孔隙度、低渗透率自生自储油藏。了解盐间非砂岩油藏生产井完井、试油、试采及生产方式,对分析盐间非砂岩油层驱油机理及储层影响因素,找出盐间非砂岩油藏开采规律很有帮助,以便寻找试验研究增加储量和产能的挖潜对策。

Non--sandstone oil reservoirs between salt layers of Wangchang Oilfield in Jianghan Basin are the self--contained source--reservoir oil accumulations with medium--low porosity and low--permeability. Understanding the well completion, testing for oil, production test and mode of production of the productive wells in non--sandstone oil reservoirs between salt layers are very essential for analyzing the oil displacement mechanism and factors influencing reservoir quality of nosandstone oil reservoirs between salt layers as well as finding out their production laws in order to establish the strategy increasing oil reserves and tapping the potential of these oil accumulations.
