摘要
利用测井资料来评价或解释沉积相的方法称为测井相分析.测井资料与沉积学结合形成的测井相分析在研究油气藏沉积相和圈定砂体方面发挥着重要作用.利用综合测井资料物性曲线的形状、幅度、数值大小,建立不同沉积相与测井曲线之间的函数对应关系,分析不同沉积相的测井曲线特征,并对不同沉积相的岩性所对应的测井曲线形态分剐进行描述,从单井分析—剖面对比—区域研究三个层次研究油气藏沉积相,勾画出主砂体的形态和展布方向.在此基础上,讨论了川口油气藏长6油层组油气藏与沉积相之间的关系,研究认为河道沉积是该区油田勘探和开发的首选区带.
The method using logging information to evaluation and interpret sedimentary facies is called logging faciesanalysis.The logging facies analysis combining Logging information with sedimentology plays an important role instudying the sedimentary facies of oil/gas reservoirs.The curve shape,amplitude,numerical value of comprehensivelogging information are utilized to establish the different homographic function relationship between sedimentary faciesand logging feature,the logging curve feature of different sedimentary facies is described in detail.The sedimentary fa-cies of oil/gas reservoirs are researched on the three procedure,such as single well analysis—section contrast—re-gional studying,the relationship is discussed between the chang—6 oil layer and sedimentary facies.On the above a-nalysis,the river course sediment is considered the best exploration and exploitation area for oil/gas reservoirs inChuankou oil field.
