松辽盆地及外围上古生界油气资源战略选区研究进展

The present situation of oil & gas resources exploration and strategic selection of potential area in the Upper Paleozoic of Songliao Basin and surrounding area,NE China

松辽盆地及外围上古生界油气地质研究和勘探程度均较低,资源前景广阔。通过油气资源战略选区工作,第一阶段针对石炭系和二叠系,开展前期的盆地评价和战略选区,实施少量的地球物理勘查和科探井工程等实物工作量,围绕古生界构造演化、地层和岩相古地理、有效烃源岩以及可能的油气远景区等方面,研究盆地深部晚古生代盆地性质,揭示在新的构造体制下不同构造阶段盆地的演化规律,基本查明松辽盆地及外围上古生界的分布、厚度、岩性、岩相特征,开展烃源岩的时效性、原型盆地恢复与重建、构造演化历史和有利成藏条件研究,提出有利远景区,供企业进一步勘探验证,这对发展和创新石油地质理论,实现松辽盆地及外围油气勘探的可持续发展,具有重要的经济社会意义。

There is a few of research and exploration on the Upper Paleozoic petroleum resources in Songliao Basin and its surrounding areas where showing good potential oil-gas resources. In recent years, potential area selection work has been carried out by China in the Carboniferous and Permian layers. Based on the field work, geophysical exploration and scientific well, characteristic of Paleozoic Songliao Basin, history of tectonic evolution in different stages of new tectonic system, the distribution, thickness, aging effect of resource rock and favorable reservoir conditions of Upper Paleozoic, have been studied and evaluated. In order to provide some area for Petroleum Company checking, potential petroleum targets have been chosen. This work is significance to develop new petroleum geological theory and keep stable and sustained devdopment of oil and gas exploration of Songliao Basin and adjacent areas.
