| 摘 要： | 通过对塔里木盆地北部阿克库勒地区 5口钻井泥质岩的声波时差及相应的孔隙度、古地层压力研究 ,求得本区的平均压实方程。认为本区 310 0～ 350 0 m属于正常压实层 ,其下属于欠压实层段。初步分析各时代流体的封闭时间和主要目的层欠压实异常类型。结合地震勘探资料 ,提出低速异常带中的更低异常区是找油领域之一。

| Abstract: | By study of acoustic time difference and associated porosity and paleostratigraphic compaction of mudstones from five drills of Akkule in the northern Tarim basin,an average compaction equation is ob- tained,which shows that the section between 310 0 m and350 0 m is the normal compaction layer,while the section below350 0 m is the sub- compaction layer.The confining time of fluids of each age is primarily ana- lyzed as well as sub- compaction anomaly type of the main target layers.In couple with seismic exploration data the further anomaly regions are pointed as one of the oil- prospecting regions. |
