沉积盆地早期评价中边界圈定的综合方法研究

中国仍有数百个盆地处于早期的油气勘探阶段,开展盆地早期评价方法研究具有十分重要的意义。本文介绍了在盆地早期评价中进行盆地边界综合研究的方法技术,指出盆地边界综合研究包括盆地的构造样式分析、物探资料处理解释、遥感结合物探资料综合圈定盆地边界等三个主要步骤。文中指出,在盆地边界的研究中,应以遥感技术为主要手段进行综合分析的思路。文中还介绍了百色盆地边界圈定的应用实例。

INTEGRATED RESEARCH METHOD OF BASIN BOUNDARY MAINLY BASED ON REMOTE SENSING IN THE EARLY STAGE EVALUATION OF OIL-GAS BASIN

There are hundreds of basins which still stand at their beginnings of petroleum exploration in China, so methodology research of early stage basin evaluation is of momentous current significance. The paper discusses systematically the integrated research method of basin boundary, which is very important in the early stage evaluation of basin. To delimit basin boundary, it points out that there are three mainsteps: ① Analysis of basin structure style; ② Processing and interpretation of geophysical data; ③ Integrated basin boundary delimitation by remote sensing technique combined with geophysical data. In the research of basin boundary, remote sensing should be taken as the main means and data integration should be taken as the main thought. Mainly based on remotely sensed and gravity data, the delimitation of the boundary of Baise Basin, China, is given as an example in the paper.
