【摘要】 柴达木盆地经过 30 多年的勘探工作,上第三系沉积、储层研究已有较好的基础,但也存在的一些不足之处,就是过多地侧重于生产,对许多基础地质问题须加强,甚至还些有争议的问题取亟待解决。如有关柴达木盆地上第三系原型盆地的恢复和上第三系全盆地岩相古地理图的编制及其形成条件的恢复等。此外,出于生产需要,还应对盆地内的有利砂体进行系统的评价和预测,本论文在前期工作的基础上,针对这些问题作深入的研究和探讨。 本论文在综合利用地质、地震、测井和分析化验资料的基础上,分析本区的物源、水系和主要沉积类型,并利用岩心、剖面和测井资料标定地震资料,并在此基础上编制全区的岩相古地理图;通过岩相古地理图,结合本区的石油地质条件和成岩作用影响,指出有利砂体类型和展布,并对砂体进行初步分类,指导油田勘探开发工作。更多还原

【Abstract】 After 30 years of oil and gas exploration and development, there are a lot of achievements about the sedimentology and reservoir research, but there are also some problems not been resolved,such as the restitution of the protobasin and the restitution of paleogeography, And the exploitation work need a system prediction about the sand bodies. This paper just aims at these points. By comprehensively utilizing the geological, seismic, well logging, analysis and test data, we analysis the material source characters and the sedimentary type of the upper Tertiary . By the base of calibrating seismic data with core and well logging data, we can research the paleogeography of the whole basin. Integrating the paleogeography factors, the geological factors and the diagenetic factors, we can present the available sand bodies and make a elementary classify to giving some suggest for the lately oil and gas exploration.更多还原
