【摘要】 低孔低渗油气储层在我国油气资源中占有十分重要地位,但目前对于它的勘探和开发无论是在勘探理论或技术上都不完善。鄂尔多斯盆地大牛地气田就是典型的海-陆相低渗透油气储层,对于它的具体地质特征目前仍不十分清楚。此次研究以现代沉积学、高分辨层序地层学和储层地质学理论为指导,结合区域地质背景,从岩心、露头、测井和化验资料入手,采用各种手段对大牛地气田低渗储层的沉积、成岩、物性等方面特征进行了精细描述。明确了研究区三大沉积体系内主要储层砂体的剖面形态和平面展布特征,对主要目的层段的物性特征做了分析对比,重点分析了该区低孔低渗储层的主要控制因素以及相对优质储层的产出规律,并优选有关的低渗储层评价参数对研究区目的层段进行了综合地质评价。更多还原

【Abstract】 Continental low permeability oil gas reservoir accounts for a rather high proportion of domestic oil gas reservoir. However, there has been not yet a suit of perfect theoretics and techniques about how to exploit the low permeability oil gas reservoir at present. Daniudi Gas Fields in Ordos basin is the typical marine-continental low permeability reservoir, of which the geological properties is not very clear. Base on the recent sedimentology, high resolution sequence stratigraphy and reservoir geology, combinated with the region geological condition, the dissertation finely descripts the characteristic of deposition, diagenesis and physical property for the Daniudi gas fields in Ordos basin, and according to data of cores, outcrop, logging and chemical examination. we explicit the characteristics of plane distribution, profile morphology of main sand reservoirs in the three deposition system and conduct contrast analyzing of physical property for the interest formatin. And analyze the main factors of influence for low permeability oil gas reservoir and the occurence of high-quality reservoirs in study area. The dissertation also synthetically evaluates the main segments based on that analysis and the optimal classification parameter of low permeability reservoir.更多还原
