摘要
塔里木盆地台盆区的轮南侏罗系JⅣ、吉拉克三叠系TⅡ和哈得逊石炭系CⅢ低电阻率油层的电阻率最低达0.45Ω·m.与水层的电阻率几乎相当。在分析其特点及成因的基础上,分别针对导致低电阻率的黄铁矿、黏土矿物以及高矿化度束缚水等附加导电因素,利用毛管压力资料,建立了油藏物性、油层高度与含油饱和度的关系以及采用高温高压岩电参数等不同的解释评价方法,取得了良好的应用效果。
With the continuous growth of exploration of Tarim Basin, some low resistivity oil formations were discovered in succession. The lowest resistivity value of the oil formations is 0. 45Ω·m which is the same as the value of the water formations. It is very important for the growth of reserves and output to identify and evaluate the low resistivity oil formations. According to the different characteristics of pyrite, clay and high salinity bound water which lead to the low resistivity of formations, the relationships of reservoir properties, pay thickness and saturation are obtained using the capillary pressure data and the rock electrical parameters under high temperature and high pressure are presented, with the different evaluation methods,good results are achieved.
