准确地判断测井剖面中的油气水层,这是油田一项十分重要的工作。 解释油气水层始终是对整个油田地质情况的不断认识过程。由于油田地质情况的复杂性,由于各种测井资料只能间接地反映岩层性质的某一个侧面,因此,至今没有一种测井方法能够单独地准确地指出地层内含有的流体性质:即孔隙内是含油,还是含水,或者油水同层以及干层。为了提高油气水层综合解释的精度,本文作者从1975年底以来,曾先后与几个油田有关方面的同志共同协作研究地质数学方法——判别分析技术在油气水
It is a very important work in the field to accurately determine the water and gas layers in the logging section. Interpretation of the hydrocarbon water layer has always been a continuous process of understanding the geology of the entire field. Due to the complexity of the geological conditions of the oilfield, no well logging method can separately and accurately indicate the fluid properties contained in the formation since the various logging data can only reflect one side of the rock properties indirectly. Thus, the pore Inside is oil, or water, or oil and water as well as the dry layer. In order to improve the accuracy of the comprehensive interpretation of oil-gas-water formations, the author of this work has worked with several oil-field comrades since the end of 1975 to study geo-mathematical methods-discrimination analysis in oil and gas water
