【摘要】：我国东部断陷盆地陡坡带中砂砾岩储层的勘探与开发越来越受到重视,但其储层物性演化及影响因素研究相对薄弱。以东营凹陷北部陡坡带古近系砂砾岩为研究对象,将22口取心井的物性数据按深度从浅至深排列起来,得到了孔隙度演化曲线。结合岩石薄片、地层水、物性分析及粒度分析等资料,从成岩与沉积作用2方面对地层水矿化度、碳酸盐含量、粒径及分选性等影响砂砾岩孔隙发育的因素进行了分析,得出胶结和溶蚀作用在垂向上均具有明显的分带性,并受地层水性质的影响和控制的结论,进而建立了该带砂砾岩垂向物性演化模型,为预测油气有利储层及判断成岩环境均提供了依据。
[Abstract]:China Eastern fault basin exploration and development in the steep slope zone of glutenite reservoir has attracted more and more attention, but its reservoir evolution and influence factors of research is relatively weak. Taking the Paleogene sandstone as the research object of the north slope of Dongying depression, physical property data of 22 coring wells in depth from shallow to deep lined up, got the porosity evolution curve. Combining rock slice, formation water, physical analysis and grain size analysis data, from 2 aspects of diagenesis and sedimentation of carbonate content, salinity, grain size and sorting of sand conglomerate influence of pore development factors were analyzed, the cementation and dissolution in the vertical direction had obvious zonation, and influenced by the properties of formation water and control results, and established the sand conglomerate vertical evolution model to predict physical properties, favorable oil and gas reservoirs and determine the diagenetic environment are provided Basis.
