| 摘 要： | 在裂缝性油气藏研究中 ,裂缝是否有效一直是测井解释的一个难点。双侧向测井是在实验的基础上 ,归纳出高、低角度裂缝在双侧向测井曲线上的响应特征 ,进而利用其曲线的重叠特征 ,找出表征裂缝有效性的两个重要参数张开度和延伸长度 (侵入深度 )与双侧向测井曲线正、负差异的关系 ,从而达到判别裂缝有效性的目的。研究结果表明 ,利用双侧向测井曲线的重叠来判别裂缝有效性的方法切实可行 ,并且具有快速、可靠的特点

| Abstract: | In the study of fracture reservoirs, determination of effectiveness of fractures is nodus in well\|logging interpretation. Based on the experiments, the dual laterolog method induces the response features of high and low fractures on dual laterolog to find connections among opening width, extending length of fracture and positive/negative separation of dual laterolog. Thus the fracture effectiveness can be determined. Results show that it is practical to determine fracture effectiveness using the overlap of dual laterolog. Comparing with other methods, this method is quick and reliable in operation. |
