    摘要:

    通过对鄂尔多斯盆地麻黄山西区块长8油组岩心观察以及综合运用普通薄片、铸体薄片、扫描电镜以及压汞等分析化验资料,在对储层成岩作用类型和特征研究的基础上,结合孔渗条件,将该区目的层段成岩相划分为四类,再结合各类成岩相电测响应特征,建立成岩相测井识别标准,完成各单井成岩相识别,在此基础上对井间成岩相的空间展布状态进行预测,并对各类成岩相发育规律进行分析、总结。研究表明,麻黄山西区块长8油组储层划分为斑状溶蚀孔隙成岩相、碳酸盐致密胶结成岩相、粘土矿物致密胶结成岩相和致密压实成岩相四种成岩相类型。斑状溶蚀孔隙成岩相主要发育在水下分流河道微相中,物性最好,横向延展性和连通性好;粘土矿物致密胶结成岩相和碳酸盐致密胶结成岩相主要发育在水下分流河道、席状砂、河口坝微相中,物性次之;致密压实成岩相主要发育在分流间湾微相和前三角洲泥微相,物性最差,连片发育,为本区最发育的成岩相类型;体现优质成岩相主要发育在优势沉积微相中,成岩相对孔渗具有控制作用。斑状溶蚀孔隙成岩相碳酸盐致密胶结成岩相中试油日产和单位产能最高,是最有利于油气富集、开采的优势相带,为下一步重点开发的区域;粘土矿物致密胶结成岩相和致密压实成岩相虽然分布范围广,但整体产能较低,分析认为主要由于这两类相带物性较差,在生产开发中应采取酸化、压裂等方式进行储层改造来提高产能。

    Abstract:

    From the analysis of cores observation, thin sections, casting thin sections, scanning electron microscopy (sem) and mercury intrusion datas of Chang 8 formation in west of Mahuangshan area,Ordos Basin,focusing on the diagenesis, pore and permeability conditions, recognize and classify diagenetic facies based on core Wells, optimizing choose GR, AC, DEN, ILD, ILM and CNL logging curve to establish the well logging identification standards of diagenetic facies, to forecast the diagenetic facies distribution. The reservoir of Chang 8 formation in studied area recognized porphyritic corroded porosity diagenetic facies, carbonate cemented tight diagenetic facies, clay minerals cemented tight diagenetic facies and compacted tight diagenetic facies. The porphyritic corroded porosity diagenetic facies mainly developed in underwater distributary channel microfacies, have best property, the best transverse ductility and connectivity. Carbonate cemented tight diagenetic facies and clay minerals cemented tight diagenetic facies mainly developed in underwater distributary channel, sheet sand, debouch bar microfacies, have better porosity. Compacted tight diagenetic facies mainly developed in distributary bay microfacies and predelta mud microfacies, with the worst porosity, continuous development, which is the best developed diagenetic facies type in studied area. High quality diagenetic facies mainly developed in advantage sedimentary microfacies, diagenetic facies have controlling function to permeability. Porphyritic corroded porosity diagenetic facies have the highest testing oil nissan and unit productivity, which means high quality diagenetic facies type mainly developed in high quality reservoir, high quality diagenetic facies is good for oil and gas enrichment.
