摘要
为了在南图尔盖盆地南缘下白垩统寻找有利岩性油气藏勘探目标,在单井沉积相研究基础上,充分利用覆盖研究区的三维地震资料,应用地震层位拉平法恢复了下白垩统K1nc沉积期古地貌,结合地震振幅属性切片技术、地震相分析等进行物源分析,划分沉积体系类型和沉积相带,预测有利砂体展布规律。研究结果表明:K1nc地层以辫状河三角洲相沉积、湖泊相沉积为主,可划分为辫状河三角洲平原、辫状河三角洲前缘和前三角洲亚相。物源早期以东西向及南西—北东向为主,晚期主要来自西南方向。研究区以辫状河三角洲前缘分流河道、席状砂和滨浅湖滩坝砂体为优质储层。本研究为进一步开展岩性圈闭勘探和估计研究区岩性油气藏储量规模提供依据。
In order to find lower Cretaceous favorable lithologic reservoir exploration targets in the southern margin of South Turgai Basin,based on the study on the sedimentary facies of single wells and 3D seismic data,the sedimentary paleogeomorphology of Lower Cretaceous K1 nc formation in the studied area is recovered by seismic horizon leveling. The provenance of the Lower Cretaceous K1 nc formation is analyzed using seismic amplitude attribute slicing technique and seismic facies analysis,the types of depositional systems and the sedimentary facies zones are divided,and the distribution of favorable sandbodies is predicted. The results show that,in K1 nc formation,there are mainly braided river delta facies and lacustrine facies,and they can further be divided into braided river delta plain sub-facies,braided river delta front sub-facies and prodelta sub-facies. The provenance of the Lower Cretaceous K1 nc formation is mainly from the directions of east-west and westsouth-eastnorth earily and mainly from the southwestern direction lately. In study area,high reservoirs are braided river delta front distributary channel,sheet and shore shallow lake dam sandbodies. The study provides the basis for the further exploration of lithologic traps and the reserves estimation of lithologic reservoirs in the studied area.
