摘要
本文建立了适合江汉盆地的压实摸型,针对不同类型的岩石,选用了不同的压实校正公式,并建立起泥质岩声波时差与孔隙度的转换关系,恢复了晚第三纪末期的地层剥蚀厚度.利用“剥皮法”对每口井逐层进行压实恢复,编绘出了各个地层在不同时期的平面展布、厚度变化、埋深变化的地层埋藏史图.整个工作中的大量计算与绘图都是利用计算机完成的.
The compaction model suitable for Jianghan Basin was established, and different compactive correcting formala were chosen for different types of rocks. Furthermore, the erosional thickness of the strata in the end of late Tertiary was restored with the conversional relation of acoustic time and porosity. Using the method of 'backstripping' , compactive restoration was progressively made for the strata in each well, and charts respective for plane development, variations in thickness and burial history were also complished. The large amonnt of computation and charting work for the study were done by computer.
