【摘要】：松南气田属于致密火山岩气藏。根据松南气田大量火山岩气井产能测试数据,以气井产能为依据进行分类,并分别统计它们的岩性、密度、声波时差、孔隙度、渗透率、阻抗范围,建立松南气田致密火山岩储层的分类标准。在此基础上,利用岩心、铸体薄片和扫描电镜,识别不同类型储层的宏观、微观孔隙-裂缝组合特征,研究不同类型火山岩储层的孔隙-裂缝发育模式。并进一步根据储层类型、地震反演孔渗参数,探讨了大型火山岩气藏潜力目标区优选方法。松南气田火山岩储层可分为I类未措施高产、II类措施后高产、Ⅲ类未措施不出气、Ⅳ类致密层四类。四类储层对应四种储层发育模式:I类储层为原生孔+微裂缝型,II类储层为次生孔+微裂缝型,Ⅲ类储层为原生孔+构造裂缝型,Ⅳ类储层为次生孔+构造裂缝型。潜力优选研究表明,YS1断块2号、3号目标体具有一定的开发潜力。储层分类更适合于本区致密储层的实际生产情况。
[Abstract]:Songnan gas field belongs to tight volcanic gas reservoir. According to the productivity test data of a large number of volcanic gas wells in Songnan gas field, the gas well productivity is classified, and their lithology, density, acoustic moveout, porosity, permeability, impedance range are counted respectively. The classification standard of dense volcanic reservoir in Songnan gas field is established. On this basis, the pore fracture pattern of different types of volcanic rock reservoirs is studied by means of core, casting sheet and scanning electron microscope to identify the macro and micro pore fracture assemblage characteristics of different types of reservoirs. Furthermore, according to reservoir types and seismic inversion of pore and permeability parameters, the optimization method for potential target areas of large volcanic gas reservoirs is discussed. The volcanic rock reservoirs in Songnan gas field can be divided into four types: type I without measures and type II without measures, type III without measures without gas outgassing, class 鈪，
