随着油田的进一步开发,钻调整井的数量每年越来越多。因为在老油区长期注水开采,严重影响了调整井的固井质量。本文认真分析了影响调整井的固井质量的因素以及提高调整井固井质量的技术关键、措施和方法,为老油区二、三次采油产层的分层处理和挖潜增加效率创造了有利的条件,使各油田原油产量在一定时期内稳产、增产得到了保证。
With the further development of oilfields, the number of well drilled wells is increasing every year. Because of the long-term water injection in the old oil area, seriously affecting the quality of cementing wells. This paper carefully analyzes the factors that affect the well cementing quality of the well and the key techniques and methods to improve the cementing quality of the well. It has created favorable conditions for the stratification of the secondary and tertiary oil production zones in the old oilfield and the efficiency of tapping potential Conditions, so that the oil production of crude oil in a certain period of stable production, production has been assured.
