摘要

摘要: 储层裂缝分布规律和单砂体时空展布特征是孔隙-裂缝型储层研究的重点,也是陕甘宁盆地上古生界中部气田获得高产的主要控制因素。通过研究作者认为,储层构造裂缝的发育与单砂体的岩性、厚度及储层所处的构造位置均有明显关系,鼻状构造高部位且岩性较粗的储层,裂缝最为发育。根据这一认识,作者对裂缝平面的分布规律进行了预测。同时文中在高精度、等时地层格架建立的基础上,从储层沉积相和沉积微相入手,研究了单砂体的展布规律和储集性能的时空变化,并对有效储层的分布进行了预测。

Abstract: The distribution rules of reservoir fissures and the space-time development characteristics of monosandbodies are focal points for the study of pore-fissure-typed reservoirs,and are also major controlling factors to the high gas production of gas fields in the middle part of the Upper Paleozoic in the Shanganning Basin.It was considered that the development of structural fissures in reservoirs is obviously related to the lithology and thickness of monosandbodies as well as the tectonic location where reservoirs are situated,and fissures are most developed in the coarse-grained reservoirs located at the high part of noses.According to this cognition,the distribution rules of fissure plane were predicted.Based on the establishment of high precision and isochronous stratigraphic framework,the development rules of monosandbodies and the space time changes of accumulation features were studied and the distribution of effective reservoirs was predicted starting with the Sedimentary facies and microfacies of reservoirs.
