摘要
本文以地面和井下化探资料，在研究区域地球化学场特征的基础上，评价下扬子地区的含油气远景。认为上古生界二叠系—三叠系是主要的勘探目的层。在区域上应以郯庐断裂东侧的泰兴－巢湖－望江一带为主要突破口。根据烃类气体含量高、组分全、衬度大的特点。本区化探成果可为评价油气聚集的有利地区提供可靠的证据。
Bsaed on underground md turface geochemical data and characteristics of regionalgeochemical field. the present paper has made oil-prospect evaluation of Lower YangtzeRegion. It is considered that the Upper Paleosoic Permian-Triassic System is the main targetbed for elploration and that. regionally. Taixing-Chaohu-Wangjiang area on the eastern side of the Tancheng-Lujiang fault should be selected as the main promising area for breakthrough in elploration. According to high content, complete components and sharp contrast ofhydrocarbon gases, geochemical achievements gained in thisarea can serve as reliable evidencefor evaluation of favorable areas of oil-gas accumulation.
