松辽盆地天然气藏地质地化成因、分布规律及远景

Geology-Geochemistry Geneses,Distribution Rules and Prospects of the Gas Reservoirs in Songliao Basin

松辽盆地是一富含油气的盆地,油气具有差异富集的特点。目前已在多套含气层系中发现了5种成因类型的气藏。解剖不同类型的气藏后发现,气藏在纵向上和平面上均有一定的分布规律;进而分出了5类气的富集带并分别指出了其勘探目标。

Songliao Basin is a rich petroleum-bearing basin. The property of differential accumulation is showed in the oil and gas reservoirs. Now, five origin types of gas reservoirs have been found in a lot of gas-bearing series. After analyzing varied gas reservoir types, it is found that a certain rule has been found in the distribution of the gas reservois in length and breadth. And then, the accumulation zones of the gases with five types are divided and their exploration targets are also pointed out respectively.
