摘要: 针对塔河油田巴楚组砂砾岩段沉积模式不明确、沉积微相研究不够深入的问题,利用岩性、钻井、录井、测井等资料,对研究区沉积模式、沉积微相类型、展布特征进行深入研究。结果表明:研究区主要发育砾岩、砂岩、泥岩3种类型的岩石,灰质含量较高;研究区主要发育3种沉积相、5种沉积亚相、13种沉积微相;沉积微相在横向上变化较快,纵向多期相同沉积微相叠置。研究区西部为辫状河三角洲沉积体系,与其侧方潮坪间互沉积;东部受阿克库勒凸起影响,距离物源近,发育扇三角洲沉积体系,与其南部潮坪间互沉积。辫状河三角洲前缘与潮坪混积的位置油气水显示相对较好,该类沉积相为有利沉积相带;研究区主体为辫状河三角洲前缘、扇三角洲前缘相与潮坪混积的沉积模式。研究结果对塔河油田的后续勘探开发具有指导意义。

Abstract: To address the issues of unclear sedimentary patterns of sandy conglomerate and insufficient research on the depositional microfacies in the Carboniferous Bachu Formation of Tahe Oilfield,the sedimentary patterns,depositionalmicrofacies type and distribution characteristics of the study area are studied by using lithology, drilling,and logging data.The results show that the study area mainly develops three types of rocks:conglomerate,sandstone and mudstone,with a high content of calcareous materials.There are 3 sedimentary facies,5 sedimentary subfacies and 13 sedimentary microfacies in the study area.The sedimentary microfacies vary rapidly in lateral,and multiple phase of the identical sedimentary microfacies are superimposed in vertical.The western part of the study area is delta sedimentary system with braided channels,which interbeds with the tidal flat on its side.A kekule by the Akkulak Uplift, the eastern part is closer to the source area.It develops a fan delta sedimentary system,which interbeds with the tidal flat in the south.The diamicton position of braided channels delta front and tidal flat shows good evidence of oil,gasand water,which is a favorable sedimentary facies belt.The main sedimentary pattern of the study area is the diamicton of braided channel delta front,fan delta front and tidal flat.The findings have guiding significance for the subsequent exploration and development of Tahe Oilfield.

Key words: depositional microfacies, sedimentary pattern, carboniferous sandy conglomerate in the Bachu Formation, Tahe Oilfield
