Abstract

Abstract: Key factors influencing the effect of plugging and fracturing was discussed, in respect to the characteristics and development status of Ch6 reservoir in Ansai oilfield, as well as features of the plugging and fracturing technology. The results showed that water breakthrough, vertical interlayer heterogeneity and initial fracturing treatment may significantly affect the plugging and fracturing performance. So, appreciate horizon for plugging and fracturing was the prerequisite for effectively reducing fluid leakage and enhancing recovery. The interaction between plugging and fracturing may also partially debase the treatment effects. Therefore, selection of proper well/layer and optimization of treatment procedure were essential for improving the plugging and fracturing effects of Ch6 reservoir, Ansai oilfield. 

Key words: Plugging and fracturing, , Influencing factors, , Well/layer selection, , Optimization of treatment procedure

摘要： 从安塞油田长6层储层特点、开发现状及堵水压裂技术特点等方面, 对影响安塞油田长6层堵水压裂效果的关键因素进行探讨。分析认为, 油井储层见水特征、油层纵向层间非均质性、前期压裂改造状况都对堵水压裂效果产生深远影响, 选择合适的堵水压裂层位是取得良好降液增产效果的前提和基础。另外, 堵水、压裂两种措施间的相互影响也部分降低了最终的堵水和压裂施工效果, 因此, 选择合适的井层和优化堵水 - 压裂施工程序成为提高安塞油田长6层堵水压裂效果的技术关键。
