| 摘 要： | 宋芳屯油田生产试验区位于姚一段杏树岗三角洲平原相的透镜状砂层之上,由于沉积物的差异压实作用形成了两个压实古背斜,其现今构造则为两个鼻状背斜。这些压实古背斜是通过趋势面分析方法发现的,并且经过对姚家组地层古厚度计算而得到了证实。研究认为此类压实古背斜是形成圈闭的重要因素。

| Abstract: | There are two compacting paleoanticlines developed by differential compaction of sediments over the lenticular sand beds of Xingshugang delta-plain facies ( first member of Yaojia Formation ) in the production test district of Songfangtun oil field. They are anticlinal noses by now. These compacting paleoanticlines are discovered by means of the trend surface analysis and verified through the calculation of fossil thickness of Yaojia Formation. By the study of the relationship between compacting paleoanticline and oil pool in this area, it may be inferred that the compacting paleoanticline is an important factor for forming the trap, where the differential compaction occurs over the lenticular sand beds. The abundant proof and a lot of maps related to compacting paleoanticlines are also given in this paper. |
