关于中国深盆气勘探的几点认识

深盆气是一种非常规圈闭型的天然气藏,具有资源量大、分布在盆地低部位、水动力封闭等特征。形成条件要求生烃强度大、储集层物性差、保存条件好、构造性质稳定等。根据深盆气地质特征及形成条件分析,中国西北一批大型盆地及南华北地区勘探前景广阔,其中鄂尔多斯盆地已经初见成效。结合其他类型的天然气资源,这个区带有可能建成中国最大的天然气生产基地,成为下世纪油气工业新的增长点。

Recognition on the Exploration for Deep Basin Gas in China

Deep basin gas is a kind of unconventional natural gas reservoir, characterized with huge qtantity of resources, distribution in the lower part of a basin and closed hydrodynamic condition. The forming requirements include great generation abilities, poor reservoir properties, favorable preserving conditions and stable tectonic setting. According to the above recognition, there is an encouraging exploration prospect in North China and some large-sized basins on Northwest China, and initial fruitage has acquired in the Ordos Basin. Adding with other kinds of natural gas resources, this area is expected to become the largest natural gas producing base and the new growth point of the petroleum industry in the next century.
