以川口地区低孔特低渗储层为研究对象,利用研究区岩心数据,物性分析数据,试油数据和测录井资料信息,对研究区内48口井进行电阻率与孔隙度测井值交会分析,用视地层水电阻率正态分布法对储层流体性质进行识别,结果表明采用孔隙度测井、分析孔隙度与电阻率交会能较好的将油层、差油层与含油水层、油水层区分开;视电阻率正态分布法能很好的识别该目的层的复杂油层流体性质。
Taking the low-porosity and ultra-low permeability reservoirs in the Kawaguchi area as the research object, the resistivity and porosity log values of 48 wells in the study area were calculated using core data, physical property analysis data, test oil data and logging data of the study area Intersection analysis, using the normal distribution method of formation water resistivity to identify the reservoir fluid properties, the results show that the use of porosity logging, analysis of porosity and resistivity intersection can better oil and poor reservoir and oil-bearing water layer, Oil and water zones are distinguished; the apparent resistivity normal distribution method can well identify the complex reservoir fluid properties of the target formation.
