油田注水开发的深层次质量监控

The Deep Quality Supervision for Water Injection Exploitation in Oilfield

在油田注水开发中，由于地层的非均质性和注水质量问题，往往导致一部分油层未水驱或水驱不见效。某油田第三系主力油田这方面的潜力就高达６９．３％。油田注水开发的质量"症结"主要是：注水井点不完善，油层对应率差；纵向单层突进，造成高低渗透层受效状况的差异；平面指进和舌进，造成大面积死油区；注入水质差，造成油层堵塞。要从根本上改善油田注水开发效果，必须按照"把好入口，分而治之，调整剖面，齐头并进"的对策，搞好油田注水开发深层次的质量监控，才能收到事半功倍的效果。

In the oilfield water injection exploitation,the problem of water injection quality and non- homogeneous formations can often lead to the ineffecive or incomplete water drive. The main problem for the oilfield water injection exploitation is the unperfection of water injection point,the poor corre- spoinding oil formations,the longitudinal single layer extruding.They may result in the different effec- tiveness in the high-low permeable stratum.stratum.Also planar planar fingering may result in large area dead oil- dom. The poor water quality may result in oil stratum clogging.In order to improve the effectiveness of the oilfield injection,a multi- measures should be taken and the effective result can be gained through the deep quality supervision for the water injection exploitation in oilfield
