长岭凹陷所图地区青山口组沉积微相及砂体分布特征
|
摘要
通过分析长岭凹陷所图地区的岩心、测井及地震等资料,研究了该区青山口组沉积微相特征及砂体展布特征。结果表明:所图油田高台子油层主要为三角洲沉积;青山口组储层可划分为三角洲平原亚相沉积和三角洲前缘亚相沉积,分别发育分流河道微相、分流间薄层砂微相、水下分流河道微相和水下分流间薄层砂微相;目的层中,GI1层、GIV2层砂岩发育较差,GI2层、GIV1层砂岩发育较好,呈片状大面积分布。
By analyzing the drill core,well logging and seismic profile in Suotu area of Changling sag,Qingshankou Formation sedimentary microfacies and characteristics of sand body distribution in this area are studied.The result indicated that the Gaotaizi oil layer in Suotu oil field was mainly the delta deposit;the Qingshankou reservoir can be divided into the delta plain subfacies deposition and the delta front subfacies deposition,which developed in distributary channel microfacies,interdistributary thin layer granulated microfacies,underwater distributary channel microfacies and underwater interdistributary thin layer granulated microfacies.In objective layers,GI1 and GIV2 layers are poorly developed sandstone,but GI2 and GIV1 layers are well developed sandstone in a larger-area lamellar distribution pattern.
