压裂低效井的控制措施

CONTROLLING MEASURES OF FRACTURED LOW EFFECT WELLS

从生产实际出发 ,认真分析了由于地质因素、施工质量和压后管理等方面产生压裂增油低效井的原因 ,论述了针对不同原因研究、制定和应用的技术措施及取得的成果 ,并在有关选井、选层标准的界定上作了大量研究工作 ,提出了高含水井、层的隔层厚度、压裂厚度、压前产液量、含水和压力等界限 ,对重复压裂井提出了技术要求 ,对特殊井的压裂提出了应采取的新工艺、新技术、新方法 。

Basing on the actual production, this paper analyzes the fracturing stimulation low effect wells caused by geologic factors, operation quality and pre fracturing management, and illustrates the techniques and their achievement. It proposes the limits of high water cut well, barrier thickness, fracturing thickness, pre fracturing production, water cut and pressure. Then it gives technical require on refractured wells and gives new technique and method for the fracturing of special wells. This has a directive significance on the effective development of oil fields.
