Title: Practice of "source rock-cap rock" joint-controlling hydrocarbon accumulation model in Panyu 4 Sag
Abstract: Based on the results and characteristics of oil and gas exploration in Panyu 4 Sag, a new hydrocarbon accumulation model is proposed which is called rock-cap joint-controlling model. The joint-controlling model shows that the dimensional allocation and superimposed relationship between source rock trend and regional cap rock play a very important controlling role on the planar migration, accumulation and dimensional distribution. It is considered that the uplift trend of source rock and cap rock is the favorable direction of hydrocarbon migration. The uplift trend of Wenchang Formation source rock has obvious zonality: in the southern part of sag, it uplifts to the west; in the northern part, it mainly uplifts to the east. And in addition, the uplift trend of regional flooding mudstone is consistent with that of hydrocarbon source rock. According to this hydrocarbon accumulation model,PY10-A and PY10-B structures are drilled with commercial discoveries, which also proves the validity and feasibility of source rock-cap joint-controlling model in exploration of Panyu 4 Sag, and has significant value for understanding the hydrocarbon migration and looking for favorable exploration targets in Panyu 4 Sag.
