| 摘 要： | 压裂、酸化是油气井增产的重要手段，它们的增产效果除取决于压裂酸化本身的作用外，还与施工后残液从地层中返排的能力有很大关系。本文以渗流机理为基础系统的分析了压裂酸化过程中排液的各种影响因素，并认为地层能量的不足和增产液对储层的伤害是影响排液的主要因素。通过对排液因素的研究可为压裂酸化施工设计及作业过程提供理论依据，提高增产作业的效果。

| Abstract: | Hydraulic fracturing and acidzing are the important methods of stimulation in the oil &gas well,their stimulation effect besides being decided by the hydraulic fracturing,acidizing themselves 'function,but also have great relationship to the ability of residual fluid flowback from the formation after execution.This article takes the transfusion mechanism as the foundation relatively systematical analysis different kinds of influencing factors after hydraulic fracturing and acidization.It reckons that insufficient formation energy and stimulating fluid induced reservoir damage are the major influence factors of clean up.Through the study of clean up factors,it could offer theoretical reference for hydraulic fracturing and acidizing working design and/or job procedure,raise effect of stimulation treatments |
