【摘要】 分析了油井压裂措施效果的影响因素,建立了油井压裂措施目标井层优选模型.该模型以模糊数学为基础,通过综合评判对侯选井层打分,优选压裂措施目标井层.应用结果表明:利用该模型优选压裂措施目标井层,简便、快捷,且优选结果可靠;按照优选出的压裂目标井层对3口油井进行了压裂,采用措施后效果明显,平均单井初期增油量达4.2t/d.更多还原

【Abstract】 Factors influencing the effect of fracturing were analyzed. An optimization model was developed which can help to choose the objective strata to be fractured. This method is based on fuzzy theory and can, by means of integrated judgment, give a score to every candidate stratum and thus optimize the selection of objective strata for fracturing treatment. The result of practical applications suggests that this method is of high reliability, and the effect is perfect. This model was used in three oil wells. Target zones were determined and fracturing were conducted on the selected zones. Good effect was achieved. The average production incremental is as high as 4.2 t/d right after fracturing treatment.更多还原
