| 摘 要： | 根据在J油田中收集到的X-射线薄片铸体资料、地层水分析资料、覆压校正孔渗分析资料、粒度分析资料、敏感性分析及试油资料等,对区域内的低电阻率油层微观机理进行了分析,认为J油田低电阻率油层的微观形成机理主要为黏土矿物及微孔隙裂缝发育作用,此外润湿性、粒度大小及地层水矿化度作用在研究区内对低阻油层的存在也有一定的影响。

| Abstract: | This paper studies the micro forming mechanism of the low resistivity reservoirs in the J oil- field, based on the data of x-ray thin cast section, formation water, overburden pressure corrected po- rosity and permeability, grain size, sensitivity and oil testing. The data shows that the micro forming mechanism of low resistivity reservoir in the J oilfield is mainly related to the occurrence of clay miner- als and micro pore fractures, wetness and particle size. The mineralization of formation water also has certain influence on the formation of low resistivity reservoirs. |
