Spatial matching relation of oil reservoir forming factors and its control effect on hydrocarbon reservoiring in the 4th Block of Toutunhe Formation of central Junggar Basin
摘要
Abstract
Based on analysis of matching relationship among oil reservoiring factors of source rock in the Toutunhe Formation,hydrocarbon infilling times,overpressure and oil source faults in the 4th Block of central Junggar Basin,effectiveness of fault transportation and effective configuration between fault and sandbodies were evaluated quantitatively by effective evaluation coefficient and fault open and closure coefficient.It is considered that hydrocarbon transports in a I-shape way.Reasonable match of effective faults and traps is the basic condition for the accumulation of oil and gas in the Toutunhe Formation.Tectonic movement leads to fault opening.Hydrocarbon generation increases the stratigraphic pressure.The pressure transfer causes oil and gas to migrate upward along the effective fault.This is the key for the accumulation of oil and gas in the Toutunhe Formation.As a result,a hydrocarbon reservoiring mode is built,which describes a mode of hydrocarbon early filling-overpressure driving-fault connecting-episodic hydrocarbon accumulation.The comprehensive analysis shows that the hydrocarbon in the Toutunhe Formation are from the Badaowan Formation,and hydrocarbon charging occurred two times.The hydrocarbon accumulation process can be divided into three episodes.Hydrocarbon accumulation and distribution are controlled by the scale of hydrocarbon generation in the Badaowan Formation and the distribution of oil source faults,and hydrocarbon accumulation is more likely to happen where reservoir is adjacent to the oil source faults.关键词
