摘要

高分辨率层序地层学分析技术广泛实用性、可行性、高精度和预测性,在沉积学和石油地质学中得到了广泛的应用并得到了广大石油地质工作者的认可。大王北洼陷沙河街二段广泛发育浅水漫湖滩坝砂体,为一种具有单层厚度薄,横向变化快,分布规律复杂等特点的砂体,勘探难度极大。因此针对此地区的滩坝沉积特殊的特点,在充分利用研究区岩芯观察、测井、地质录井、三维地震以及室内样品分析数据等资料的基础上,运用高分辨率层序地层学对研究区沉积地层格架和沉积相的分布、演化特征做了分析。预测了研究区有利勘探储集层分布。
Stratigraphy has been accepted by most geologists and widely applied to oil and gas exploration and development since it was introduced into China due to its wide applicability,feasibility,high accuracy and predicability.It has played an important role in oil and gas exploration and development in China.The main depositional system of the Shahejie 2nd Formation is the beach and bar in Dawangbei Sag;But the beach-bar sandy body,the thickness of which is thin,change very quickly in the landscape orientation,distribution of which is complicated.The exploration of the beach-bar sandy body is very hard.At present,the research of inner structure and void distribution on beach and bar sandy body is not consummate all over world and is unsubstantial in research area.In this paper base on the data of core,logging,3D seismic,etc.,we analyze the kigh resolution sequence and the evolvement of sedimentary facies,and distribution of reservoir body and the establishment of play.
