摘要
分析低阻油层的形成机理以及沉积环境,总结形成规律,找出有利沉积亚相,提高勘探和开发效率。形成机理主要包含:(1)地层因素如,电阻率值及含油饱和度、高矿化度地层水、低幅度构造、束缚水饱和度、粘土矿物特征、润湿性、砂岩复杂孔隙结构等;(2)钻井液侵入;(3)砂泥岩薄层互层。
The formation mechanism and sedimentary characteristics of low resisitivity oil layers were comprehensively analyzed,the formation regulation was discussed,the best sedimentary facies belts were determined to improve the efficiency of exploration and development.The results show that the main formation mechanisms are as follows： formation factors,such as oil saturation and resistivity,high formation water salinity,low amplitude structure,irreducible water saturation,clay mineral,water affinity,the complex pore configuration of sandstone;drilling fluid invasion;thin alternating bed of sanstone and mudstone.
