松辽盆地北部高台子地区扶余油层沉积微相分析
|
摘要
扶余油层属于松辽盆地大型坳陷阶段沉积形成的下部旋回,以浅水湖泊—三角洲沉积体系为主。该地区存在的主要问题是受到多物源控制形成的错叠连片分流河道砂体、砂体薄、物性差、产能低。通过对高台子地区109口井的岩心观察、录井和测井曲线的分析,确定了岩相类型,结合测井相、骨架剖面的分析,将扶余油层划分成3个油组、17个小层,并对17个小层的沉积微相展布及其演化规律进行分析。分析表明,研究区域内主要发育浅水三角洲沉积体系,以河流相和三角洲平原亚相为主,其中扶一油层组为三角洲前缘亚相,扶二、三油层组为三角洲平原亚相或河流相,分流河道砂体是最有利的储集砂体,为研究区进一步高效开发提供了技术支持。
The Fuyu oil layer belongs to the lower cycle of sedimentary formation in the large depression stage of Songliao Basin and was mainly composed of shallow lacustrine deltaic sedimentary system.The main problem in this area was that the overlapped distributary channel sand bodies formed by multiple source controls were in thin sand bodies,poor in physical property and low in productivity.By analyzing the core observation,logging and logging curves of 109 wells,the lithofacies types have been determined,with the analysis of logging facies and skeleton profiles,the Fuyu oil layer was divided into 3 oil formations and 17 small layers,and the microfacies distribution and evolution law of the 17 small layers were analyzed.The analysis shows that the shallow water delta system is mainly developed in this area,mainly in delta plain subfacies and fluvial facies,the FⅠ reservoir was delta front subfacies,and the FⅡ and FⅢ oil reservoir is delta plain subfacies or fluvial facies,distributary channel sand body is the most favorable reservoir sand body,it provides technical support for further efficient development of the study area.
