Quantitative analysis of control of faults on hydrocarbon accumulation in the west of Bozhong Subsag of Bohai Sea:A case study of CFD12-6 Oilfield
摘要
Abstract
In order to understand the control of faults on hydrocarbon accumulation in the Neogene of the west of Bozhong Subsag,based on the detailed analysis of fault structure,distribution characteristics and transport mechanism,it was first proposed to quantitatively evaluate the vertical transmission capacity of the faults by using the fault-caprock parameter and fault-transporting ability index.The result indicates that the fault-caprock parameter and fault-transporting ability index can effectively quantitatively characterize the hydrocarbon charging capacity and hydrocarbon accumulation strata of different tectonic belts in CFD12-6 Oilfield.In the northern fault zone,the fault-caprock parameters are larger and the faulttransporting ability index is smaller,and thus the hydrocarbon charging capacity is relatively weak and the hydrocarbon is mainly accumulated in the Guantao Formation;while in the southern fault zone,the fault-caprock parameters are smaller and the fault-transporting ability index is much larger,and thus the hydrocarbon charging capacity is much stronger and the hydrocarbon is mainly accumulated in the Minghuazhen Formation.Based on the fault transmission capacity,the hydrocarbon accumulation models for the north-south fault zone in CFD12-6Oilfield were established.The "HydrocarbonFault-Sand" lateral diversion reservoir model is for the northern fault zone;while the "Hydrocarbon-Unconformity-Fault" vertical penetrating reservoir model is mainly for the southern fault zone.关键词
