摘要
利用岩石物理和测井手段分析了伊朗A油田海相碳酸盐岩储层的岩性、物性、孔隙类型、物性控制因素、裂缝系统发育状况,并从纵向上和横向上对储层的物性发育状况进行了分析,提出了有利钻井带。在A油田其孔隙空间类型为裂缝孔隙型,物性发育状况受到白云岩化程度、储层结构组分的配比、毛管半径(孔隙结构)及裂缝的发育状况的控制。研究发现X1井区为良好的物性发育带,适宜打井眼轨迹垂直于背斜长轴方向的水平井。
The carbonate reservoir properties,such as lithology,porosity,permeability,space type,controlling factors of physical property and the physical property development characters in longitudinal and horizontal distribution were analyzed,and the favorable drilling area was given.The main pore type of an oilfield was fracture-pore and the physical property controlled by the degree of dolomitization,partitioning of the textural components,radius of capillary (pore structure) and fracture.Wellblock X1 is good for drilling horizontal wells vertical to the long axis of the anticline.
