| 摘 要： | 致密砂岩储层中裂缝的发育是影响储层品质的关键因素,能准确判断储层中裂缝的有效性对储藏层产能的提升具有重要的意义,用单一的电成像或声成像方法都有一定的局限性,不能对裂缝进行全面的评价。本文在对致密砂岩储层裂缝特征及其测井响应的基础上,论述了利用声电成像测井资料综合分析判定致密砂岩地层裂缝有效性的原理和方法。就库车地区裂缝性致密砂岩储层中的实际应用效果,说明了该方法的可行性和准确性。

| Abstract: | Fractures in tight sandstone reservoir is a key factor affecting the quality of reservoir,so to determine the effectiveness of fracture is very important for raising reservoir productivity.But using a single electrical imaging or acoustic imaging method has some limitations,which is unable to evaluate the fracture comprehensively.Based on the tight sandstone reservoir fracture features and logging response,we discussed the the principle and the method of determining the effectiveness of tight sandstone reservoir fracture using acoustic-electric imaging data.The case study from fractured tight sandstone reservoir in DaBei area of Tarim basin shows the feasibility and accuracy of this method. |
