摘要
本文根据塔里木盆地西南坳陷和什拉甫地区中新统岩石学特征,研究了和什拉甫地区的沉积相展布及演化特征,明确了该地区的沉积相,为石油勘探提供了可靠的沉积依据。和什拉甫地区沉积相类型为冲积扇──扇三角洲──湖泊沉积体系,进一步分为几种亚相类型和微相类型。区内具有比较好的生、储、盖条件及岩性圈闭条件。
This paper discusses the evolution of sedimentary facies of Heshilafu region in south - west depsression of Tarim basin according to the Miocene petrologic characteristics. The determination of sedimentary facies provides reliable basis for petroleum exploration in this rngion. The sedimentary facies in Heshilafu is an alluvial fan - fan delta -lake systetn, and it can be further devided into several parfacies including microfacies. In the research region, there are good conditions in oil generation, containing and covering and trap lithological traps.
