The Origin of Sublacustrine Fan and Its Significance for Exploration in Northern Chexi Sub-Sag, Jiyang Depression

Abstract

Abstract: The sublacustrine fan, as an important deposit in actic region of northern Chexi sub-sag, is characterized with both source and reservoir in it and favorable hydrocarbon accumulation conditions. According to the difference of the genetic mechanism, it is further divided into the slump turbidite fan and the deep-water turbidite fan for they have some differences in seismic profile, depositional character and space distribution. It is suggested that this fan is of good reservoir quality and oil-bearing property due to the effect of the profile structure and the abnormal high pressure fluid compartment, thus having higher values for petroleum exploration.

Key words: Jiyang depression, Chexi sub-sag, sublacustrine fan, actic region, origin, fluid compartment
