| 摘 要： | 巴喀气田位于吐哈盆地北部凹陷,下侏罗统八道湾组致密砂岩储层是巴喀气田重要的产气层位。根据测井、录井、岩心资料,对巴喀气田工区内沉积岩的颜色、岩性、沉积构造、测井相等相标志进行了分析研究,认为巴喀气田下侏罗统八道湾组主要沉积相为辫状河三角洲相,以辫状河三角洲前缘亚相为主,主要发育水下分流河道、河道间、河口坝、前辫状河三角洲泥坪和沼泽5种沉积微相。在单井相,连井剖面相研究的基础之上,描述了区内典型小层的沉积相平面展布特征,最终确立了研究区八道湾组的沉积相模式。

| Abstract: | Baka gas field Located in the northern sag of Tuha basin,lower Jurassic tight sandstone reservoir of Badaowan formation is an important gas-producing reservoir.Based on whole exploration and development of Baka gas field,in combination with well logging,mud logging and core data,the analytical research on color and lithology of sedimentary rocks,of sedimentary structure and logging facies has been carried out.The results indicate the main sedimentary facies of lower Jurassic Badaowan formation is braided river delta facies,mainly with braided river delta front subfacies,main-ly developing five kinds of sedimentary microfacies,underwater distributary channel,interchannel,mouth bar,braided river prodelta mudflat and marsh.On the basis of wellto-well profile facies study,sedimentary facies plane distribution characteristics of typical small layers has been described and the sedimentary facies model of Badaowan formation has been established finally. |
