大庆油田为了解决油田开发中后期油层产量逐年递减的矛盾,最大程度开发利用外围油田,提高外围油田采收率,近几年又进一步加大了开发力度,调整井、更新井、侧斜井的钻井数量连年增加。而外围油田的特性是低渗、低压、低产能,加之多年的注水开发,套损井逐年增多,使地层蹩压,油气水侵,井塌等复杂情况时有发生,固井质量难保证。为了保证固井质量,我们采取了一些有针对性措施,取得了良好的效果。 Daqing Oilfield in order to solve the contradiction between the production of oil and gas in the middle and late stages of the oilfield decreasing year by year, to maximize the development and utilization of peripheral oil fields and improve the recovery rate of peripheral oil fields. In recent years, Daqing Oilfield has further increased its efforts in development, adjustment wells, The number of drilling increased year after year. The characteristics of peripheral oilfields are low permeability, low pressure and low productivity. Combined with years of waterflood development and casing damage increasing year after year, complicated conditions such as formation lag, oil and gas invasion and well collapse occur frequently and the quality of cementing is difficult to guarantee. In order to ensure the cementing quality, we have taken some targeted measures and achieved good results.
