裂缝型储集层

文昌A凹陷储集层可分为砂体储集层和裂缝型储集层两大类。

The reservoirs in Wenchang A sag can be divided into two types : sandstone and fracture reservoirs .

裂缝型储集层对于油气聚集具有重要意义，但是其地质情况复杂，油气识别困难。

Fracture reservoir has an important meaning for hydrocarbon accumulation , but it has a complex geological circumstance and is difficult to distinguish .

通过精细解释和综合分析，预测了裂缝型储集层分布范围，刻画了孔隙度空间展布特征，以此为基础在白云岩区新增控制储量991×104t。

Finally , through detailed interpretation and composite analysis , such a reservoir 's distribution scope is predicted , the porosity distribution features are delineated , by which the newly incremental control reserves of 991 × 104 t have been obtained in this area .

巴喀油田中侏罗统砂岩属特低渗透裂缝孔隙型储集层，平均渗透率为0.3×10-3μm2；

Sandstone reservoir of Middle Jurassic in Baka oil field is of lowest permeability , which is fracture and pore , and the average permeability is only 0.3 × 10 - 3 μ m 2 on the ground .

古潜山主要发育风化壳岩溶带储层和内幕储层。下古生界碳酸盐岩裂缝-溶蚀型储集层的发育特征以有无上古覆盖是岩溶发育的前提；

The buried-hills mainly develope two kinds of reservoir , one is related to the crust of weathering and karst zone , the other is to lithology .
