在致蜜的碳酸盐岩地层中,天然裂缝使它可能成为串富的产油层。这些广泛发育的裂缝,通常大多是垂直或近似垂直的。贝克(1955)计算表明,如果地层有O.05英寸宽的裂缝,它等价于568英尺渗透率为1000毫述西的无裂缝性地层。因而,对这种含有裂缝韵储集层的油井评价,很大程度取决于寻找裂缝的技术。最现代化探测与区分垂直裂 In the honey-bearing carbonate formations, natural fractures make it possible to become a string-rich oil producing layer. These widely developed fractures are usually mostly vertical or approximately vertical. Baker’s (1955) calculations show that if the formation has a 0-inch-wide crack, it is equivalent to a fractured formation of 568 feet with a permeability of 1000 milliseconds. Therefore, the evaluation of wells with fractured reservoirs depends very much on the technique of finding fractures. The most modern detection and differentiation of vertical cracks
