摘要
There are two sets of source rocks in Carboniferous in the Malang sag, namely upper Haerjiawu Formation and lower Haerjiawu Formation. And source control effect is obvious on reservoir formation in this area. It is found that the formation and distribution of different types of crude oil are strictly controlled by the distribution of the corresponding source rocks using the geochemical comparative analysis of the source rock and crude oil as well as the oil-source correlation. The analysis indicates that the main controlling factor of hydrocarbon accumulation is the reasonable configurations of high- quality source rock, strongly recharging of hydrocarbon into faults connecting source rock and reservoir, and favorable volcanic rock facies belt.
