摘要

摘要: 鄂尔多斯盆地西北部姬塬地区与东南部黄陵地区延长组长8段储层物性存在较大的差异,利用粒度、铸体薄片、扫描电镜等储层岩石学分析手段和对比的研究方法,围绕面孔率,通过分析粒间孔、次生溶孔的影响因素,明确储层主控因素,揭示储层致密机理。结果表明,沉积体系控制了储层的岩石学组成及不同物理、化学稳定性碎屑的含量,控制了引起次生溶孔发育的长石等易溶组分含量,控制了刚性、半塑性、塑性等不同力学性质的碎屑含量;沉积环境控制了储层碎屑颗粒的粒度和分选;泥级碎屑组分含量制约和影响着部分黏土类自生矿物的含量;沉积体系和沉积环境的差异是两区粒间孔和次生溶孔发育存在差异的决定因素,也是导致储层物性较大差异的主要原因。

Abstract: There are obvious differences of reservoir physical properties of Chang8 sandstones between the Jiyuan area in the northwest and the Huangling area in the southeast of the Ordos Basin. The factors influencing intergranular and dissolution pores were discussed based on granularity, thin section and SEM analyses. In this way, the controlling factors for reservoir physical properties and the mechanism for reservoir compaction were determined. The deposition system controlled the petrologic composition of the sandstones, the content of minerals with different physical and chemical stabilities, the content of feldspar, which caused secondary porosity, and the content of minerals with different mechanical properties (rigid, semi-plastic or plastic). Depositional environment controlled the granularity and sorting of clastic compositions in reservoir. The content of detrital mud components controlled the content of authigenic clay minerals. The difference in deposition system and environment between the two areas led to the difference of intergranular and dissolution pores, and explain the obvious differences of reservoir property.
