短距离不规则井眼堵水技术与实践

WATER PLUGGING TECHNOLOGY AND PRACTICE IN SHORT DISTANCE AND IRREGULAR BOREHOLE

在短距离不规则井眼中对水层进行有效封堵是目前堵水的一个较难处理的问题。CX565井修井后需在短距离和"大肚子"的裸眼井段内采取措施对下部水层进行封堵。通过论证分析,引进并采用了BAKER公司的PIP封隔器进行堵水作业。通过CX565井的现场应用表明,该技术能在短距离不规则井眼内有效封堵下部水层,具有一定的推广应用价值。

To plug water layer in short distance and irregular borehole effectively was a difficult problem for water plugging at present.The water layer in CX565 well with short distance and ir-regular borehole should be plugged after workover.After discus-sing and analyzing carefully,the PIP packer was introduced from the Baker Oil Tools,and carried out the water plugging operationin CX565 well.The plugging result showed that the packer could plug the bottom water effectively in short distance and irregular borehole,it was worth popularizing and applying in similar well condition.
