propped fracture area

In addition, we advance that effective porosity,Permeability and effective volume of fractures controled by signal well could take as foundation ahat differentiating classes of fractured reservoirs and evaluating fractures.

在系统介绍岩芯裂缝基本参数统计的基础上，给出岩芯裂缝空间分布规律的表示方法，并概括了裂缝孔隙度和渗透率的估算方法，提出有效孔隙度、渗透率和单井控制的有效裂缝体积可作为裂缝性储集层等级划分和裂缝综合评价的依据。

Prediction of effective fractures in a limestone buried hill,South China Sea;

中国南海某盆地A凹陷灰岩潜山有效裂缝预测

The directions of earth stress in ancient and modern time and the dominant azimuth of effective fractures are forecasted.

在此基础上 ,划分了裂缝类型 ,总结了裂缝的平面展布规律 ;预测了古、今地应力方向及有效裂缝优势方
