碳酸盐储集岩的非均质性及其主要控制作用研究

THE HETEROGENCITY OF CARBONATE RESERVOIR AND ITS MAIN CONTROLLING FACTORS

碳酸盐岩储层由于沉积作用多变、岩石的物理-化学性质不稳定,在复杂多样的成岩作用下,岩石表现出强烈的非均质性。掌握这种非均质性的三维发育情况是勘探工作的重点,通过对碳酸盐岩非均质性各控制因素的研究,并利用这些因素进行储层综合评价,可以寻找到最有利储层的发育地带,就是各种有利因素均很活跃的地区,并以此指出了下一步勘探的方向。

There are often showimg heterogencity for carbonate reservoir because of changeable sedimentation and unstable physical and chemical properties of rocks,which under complex diagen- esis.It is key point of exploration to master this three-dimensional heterogencity of rocks which be inforrned us the direction of explorationand may be found the new region where will be best car- bonate reservoir by studing the controlling factors of heterogencity,and synthesize all the factors to evaluate reservoir.
