应用高分辨率层序地层学理论及方法,对濮城油田南区沙二上亚段2+3砂层组进行了精细的地层对比,划分出两个中期基准面旋回,13个短期旋回,其中沙二上亚段2和沙二上亚段3砂岩组各对应一个中期旋回。在此基础上将沙二上亚段2砂岩组和沙二上亚段3砂岩组各细分成7个小层,从而对研究区沙二上亚段2+3砂层组进行了精细的地层对比,为油田进行更加精细的油藏描述提供了依据。
By using the theory and method of high resolution sequence stratigraphy, the stratigraphic comparisons of 2 + 3 sandstones in the Upper Es2 of Pucheng Oilfield are carried out. Two medium-term base-level cycles and 13 short- Among them, the Upper Member 2 of Upper Shahejie 2 and the Upper Member 3 of Shahejie 3 sandstone correspond to a medium-term cycle. On the basis of this, subdivided the Sandstone Member 2 sandstone group 2 and the Sandy Member 2 sandstone group into 7 sub-layers, so that the fine strata The comparison provides a basis for the oilfield to carry out more elaborate reservoir description.
