在综合分析济阳坳陷内所测六十多口井的地层倾角资料和其他探井地质资料的基础上,本文探讨了用地层倾角测井研究陆相盆地内古沉积环境和沉积相的方法。文中阐述了解释原理和方法,并以实例具体叙述应用地层倾角资料划分各种沉积层理构造,识别点砂坝、河道砂坝、河口砂坝、沿岸砂坝和浊积岩,判断古水流方向和砂体延伸方向及其加厚方向的方法。实践证明,地层倾角测井是寻找非背斜圈闭的有效手段。
Based on the comprehensive analysis of the formation dip data and other exploration well data of more than 60 wells measured in the Jiyang Depression, the paper discusses the method of studying the paleo-sedimentary environment and sedimentary facies in the continental basin by using the dip logging. The paper explains the principle and method of interpretation, and concretely describes the application of stratigraphic dip data to divide various sedimentary stratigraphic structures, identify point sand bar, channel sand bar, estuarine sand bar, sand bar and turbidite along the coast, and determine the direction of paleocurrents And sand body extension direction and the method of thickening direction. Practice has proved that stratigraphic dip logging is an effective way to find non-anticlinal traps.
