综合地球物理方法对黄海地区前新生代残留盆地分布的研究

Applying integrated geophysical methods to study distribution of pre-cenozoic residual basins of Yellow Sea

残留盆地由于埋深大、构造复杂等特点,单一的地球物理方法对残留盆地的勘探与解释存在很大的局限性,因此运用综合地质地球物理方法对前新生代残留盆地进行研究,可以充分发挥各种方法的优势,有效地解决油气勘探中的有关问题.本文以黄海地区前新生代残留盆地为研究对象,以"区域控制局部,深层约束浅层"为指导思想,在前人研究的基础上,运用重、磁、地震、钻井和区域地质等资料进行了综合研究,根据研究与计算结果勾绘了黄海地区前新生代残留盆地的宏观构造格架,并分析了残留盆地分布特征.

Pre-Cenozoic residual basins are usually buried deep and then transformed many times in its long evolutional history. These characteristics make it difficult to apply a single method in exploring Pre-Cenozoic residual basins, On the other hand, it is highly effective to solve key problems of gas and oil exploration of Pre-Cenozoic residual basins by using integrated geological and geophysical methods which make full use of the advantages of various exploring techniques. Based on results of research and calculation, we drew distribution of Pre-Cenozoic residual basins of Yellow Sea.
