目前国内外许多地质家一致认为,在掌握了大量现代和古代的各种沉积模式的基础上,在新区勘探和开发的初期,沉积学工作者完全可以根据该区有限的资料,对其沉积环境和模式作出正确的解释,对进一步勘探和开发作出预测。本文分别叙述牛居和青龙台两个油田小层沉积相研究结果,及其在编制开发方案中的作用。一牛居油田的马圈子油层属于下第三系东营组下部地层,是一套巨厚的砂泥岩互层沉积。砂岩以含砾细-粗砂岩为主,泥质岩以紫褐色和灰绿色块状为主,厚达400米左右。砂 At present, many geologists at home and abroad agree that on the basis of grasping a great deal of modern and ancient sedimentary models, in the early stage of exploration and development in the new area, sedimentologists can fully understand the sedimentary environment based on the limited information in the area And model to make the right explanation for further exploration and development to make predictions. This paper respectively narrates the research results of the small sedimentary facies of Niuju and Qinglongtai oilfields and their functions in compiling and developing the scheme. The Majuzi Formation of a Niuju Oilfield belongs to the lower part of the Dongying Formation of the Lower Tertiary. It is a set of huge thick sand-mudstone interbedded sediments. The sandstone is mainly composed of gravel fine-coarse sandstone, and the main types of mudstone are purple brown and gray-green massive with a thickness of about 400 meters. sand
