不整合面代表着区域性的沉积间断或剥蚀事件,对油气运移成藏都有着重要作用。不整合在空间上分为不整合面之上的岩石、不整合面之下的风化黏土层及半风化岩层。不整合可划分为平行不整合、超覆不整合、削截不整合、褶皱不整合、断褶不整合等多种类型。不整合对油气成藏及分布既有建设性作用,也有破坏性作用。
Unconformities represent regional sedimentary discontinuities or denudation events that play an important role in hydrocarbon migration and accumulation. Unconformity is divided into rocks that are spatially divided into unconformity, weathered clay and semi-weathered rock under unconformity. Unconformity can be divided into parallel unconformity, unconformity, unconformity, fold unconformity, fold-fold unconformity and other types. Unconformity has both a constructive and destructive effect on hydrocarbon accumulation and distribution.
