沙湾凹陷百口泉组层序地层及沉积体系研究
Study on Sequence Stratigraphy and Deposit Systems of the Baikouquan Formation in Shawan Sag
摘要
Abstract
Aiming at the problem that the sequence stratigraphy framework and deposit systems of the Baikouquan Formation in the Shawan sag within the Junggar Basin are not clear yet,we integrated the study methods of sequence stratigraphy and sedimentology,applied multiple seismic attribute analysis method to study the distribution feature of the sedimentary facies,and then predicted the favorable regions.The study results show:(1) the Baikouquan Formation can be divided into three 3rd-order sequences,and the inside of each 3rd-order sequence can be classified into two system tracts (lacustrine transgressive tract and lacustrine regressive tract) according to clastic deposit model;(2) there is fan delta-lacustrine deposit system that include three subfacies (fan delta plain,fan delta front and shore-shallow lake) and five microfacies;(3) the favorable regions can be divided into three grades,and the underwater distributary channel microfacies in fan delta front with interlaced development of faults within burial depth of 5000 m is the most favorable.This conclusion can provide base for future exploration direction.关键词
