前言 随着石油勘探的进展,人们重视研究含油区断裂与油气聚集的关系。断裂控制油气聚集在我国很多含油气盆地中起了重要作用,克拉玛依油田为逆掩断裂控制油气聚集的一例。研究克—乌断裂的形成机制与油气聚集具有重要的理论意义和重要的经济意义。 一、克—乌断裂的大地构造位置 我国西部主要石油产地克拉玛依油田,位于准噶尔盆地西北缘,为西准噶尔海西地槽封闭后形成山前盆地,略相当于Dikesen划分的逆掩体前陆盆地。克—乌断裂是一个
Preface With the progress of petroleum exploration, people pay attention to study the relationship between oil-bearing faults and hydrocarbon accumulation. Fracture Control Hydrocarbon accumulation plays an important role in many petroliferous basins in China. The Karamay Oilfield is an example of oil and gas accumulation controlled by the overthrowing fault. It is of important theoretical significance and important economic significance to study the formation mechanism of Cretaceous-Kenyan fault and hydrocarbon accumulation. The tectonic position of the K-Wu fracture The Karamay oilfield, the main petroleum production site in the western part of China, is located in the northwestern margin of the Junggar Basin. For the closure of the Hercynagogeny in the West Junggar, the foreland basin is formed and is slightly equivalent to the anti-bunker foreland basin divided by Dikesen. K-Ukraine fracture is one
