阿姆河盆地阿盖雷地区牛津阶碳酸盐岩储层特征
|
摘要
阿姆河盆地阿盖雷地区在Aga-21井和Aga-23井于牛津阶碳酸盐岩钻获高产工业气流,详细研究该区牛津阶碳酸盐岩储层特征,对整个地区的勘探开发具有重要指导意义。在岩心描述的基础上,通过铸体薄片、扫描电镜和储层物性等资料的综合分析,结合测井及地震资料,认为牛津阶碳酸盐岩储层发育和分布受沉积微相和成岩作用共同控制,砂屑滩和生屑滩为储层发育的基础,溶蚀作用为储层形成的关键因素,破裂作用有效地提高了储层品质。同时指出砂屑滩和生屑滩为有利储层发育的沉积微相,是今后主要的勘探开发目标。
High-yielding industrial gas had been gained in Oxfordian carbonate rocks in Agayry area,Amu Darya Basin,thus a detailed study on the characteristics of the reservoir will be important to guide its hydrocarbon exploration and development.Based on the detailed description of drilling cores and comprehensive analyses of casting thin sections,scanning electronic microscope and reservoir properties,it was believed that the reservoir and its distribution are mainly controlled by sedimentary microfacies and diagenesis.The sandy beach and bioclastic beach are the foundation of the reservoir development,dissolution is the key factor for the reservoir formation,and the fracturing greatly enhanced the reservoir quality.All these features improved the accuracy of the reservoir prediction and evaluation,and provides principles for the efficient development of gas resources.
