古剥蚀幅度的恢复是反演盆地埋藏史和油气生成史的前提条件 .利用黄骅坳陷现有数十口探井钻到的古生界地层资料 ,采用频数分布统计的方法建立该区综合地层厚度剖面 ,在此基础上 ,试用镜质组反射率 R0 法 ,对该区上、下古生界地层之间假整合面的平均剥蚀幅度进行了尝试性研究 ,并以分子级成熟度参数 C2 9Ts/C3 0 H对所得结果加以验证 ,表明黄骅坳陷上、下古生界间假整合面的最小平均剥蚀幅度为 440 m,同时 ,也说明该方法简便可行 ,有值得参考借鉴之处
The restoration of ancient ablation rate is a prerequisite for the inversion of the burial history and hydrocarbon generation history of the basin.Based on the Paleozoic strata data from the existing dozens of exploration wells in the Huanghua depression, the frequency distribution statistics are used to establish the integrated formation thickness Based on this, the vitrinite reflectance R0 method was used to try to study the average ablation amplitude of the fake surface between the Upper Paleozoic and the Lower Paleozoic strata. The molecular maturity parameters C2 9Ts / C3 0 H to verify the results obtained, indicating that the Huanghua sag between the upper and lower Paleozoic fake intercepts the minimum average surface erosion rate of 440 m, but also shows that the method is simple and feasible, there is a reference for reference
