为理清哈萨克斯坦肯基亚克盐上油田白垩系砂体成因特征，指导油气田开发。在高密度井网条件下，利用岩心、岩石薄片、分析化验、古生物、测井等综合资料，研究储层砂体的粒度、结构、成分及砂体平面展布规律。结果表明：白垩系下统巴列姆组储层主要是细砂岩及粉－细砂岩；具有小型交错层理和水平层理，砂岩成分成熟度中等、结构成熟度较高。西北部三角洲平原有明显的二元结构及向上变细的正韵律，砂体整体呈朵状展布，具有典型的曲流河三角洲沉积特征；可识别出三角洲平原、三角洲前缘、前三角洲、浅湖4种亚相以及水上分支河道、水下分支河道、浅湖砂坝等10个微相，并分析了各微相的沉积特征及砂体展布形态；其中巴列姆二段时期三角洲前缘亚相主要分布在工区中西部，巴列姆一段时期工区整体演变为前三角洲———浅湖亚相，为一典型的退积式三角洲；该研究结果为肯基亚克油气田的开发提供了重要的地质依据。

In order to clear the cause of sand body of the lower Cretaceous in up-salt Kenjiyake oilfield , the oil and gas fields ’ development were guided .Therefore , under the condition of dense well pattern , the comprehensive data of core, rock slices, analysis and laboratory, ancient biology, well logging and so on to study the granularity , structure , composition of the sand body ’ s reservoir and the distribution law of sand body was used .Then the results show that:the reservoirs in Baliemu formation of the middle Cretaceous are mainly fine sandstone and siltstone ;Sandstone has some small cross bedding and horizontal bedding ;the compositional maturity of sandstone is medium while the texture maturity of sandstone is high .Delta plain that is in the northwest has the Dual Structure .Vertical-ly,the upper the sequence , the finer the grain size ; The sand body in the study area is distributed in a single shape , this form has the typical sedimentary characteristics of the meandering river delta;In this areas have been identified delta front , delta plain , frontal delta , shallow lake , including 10 kinds of microfacies:distributary chan-nel, subaqueous distributary channel , shallow lake sand bars , ect.At the same time the distribution patterns of sand bodies and the sedimentary characteristics have been analyzed;During the second member of Baliemu forma-tion period delta front subfacies main distribute in the west of the study area , while in the first member of Baliemu formation period the whole area evolves the former delta-shallow lake subfacies which is the typical retrogradational delta;This study provides important geological basis for the development of Kenjiyake oilfield .
