Distribution and controlling factors of hydrocarbon reservoirs in continental fault basins
Online published: 2007-06-15
In recent years,with the development of oil and gas exploration in continental fault basins in eastern China, continental oil geology theory has gradually formed with the representation of“Continental Oil Generation”and“Source Control Theory”. From the former anticlinal reservoir exploration to nowadays subtle reservoir exploration, the hydrocarbon formation and distribution rules of continental fault basin can be divided into four historical stages:1960′s ~1970′s,“Source Control Theory”,proposed on the basis of the discovery of Daqing Oilfield; in 1980′s“, composite zones of hydrocarbon accumulation theory”based on the exploration achievements in continental fault basins, especially Bohai Bay Basin; in 1990′s,“oil accumulation around the sag”concluded by the geologists during the exploration in Shenli Oilfield;till now, new viewpoints of“complementarity characteristics”(2003),“predominance characteristics”(2005),“multi-factor controlling and key- factor entrapping”( 2006) presented during the study on the subtle reservoir exploration in Erlian Basin. All these viewpoints not only take a significant part in the exploration in continental fault basins, but also improve the oil geology theory with the representation of “Continental Oil Generation”.
