随着油田开发的逐步进行,井下作业成为油田生产当中不可或缺的一部分,不论是新井投产,老井维护,或者是油气当量的稳产增产都离不开井下作业队伍的施工。常规的井下作业施工包括,冲砂、注灰、磨铣、套铣、钻塞等。因其施工工序快,见效好得到了采油厂的青睐。但随着油田开发进入到后期,地质结构不断复杂化的情况下,各项施工难度也逐渐增加,由于地层情况多变造成的工序失败也逐渐增多,如何增加施工一次成功率,提高施工生产时效这一课题也逐渐摆在了我们作业人员眼前。针对这一情况本文选出了冲砂、注灰两方面谈谈笔者的常规施工心得,供大家参考,和大家一起探讨共同进步。
With the gradual progress of oilfield development, underground operations become an indispensable part of oilfield production. Whether it is the commissioning of new wells, the maintenance of old wells, or the stable production and increase of oil-gas equivalent, it is inseparable from the construction of underground operation teams. Conventional underground construction operations, including sand, ash, milling, milling, drilling and so on. Because of its construction process fast, effective get oil plant of all ages. However, with the development of oilfields entering into the late stage and the complicated geological structure, the difficulty of construction gradually increases. Due to the change of stratum condition, the failure of procedures also increases gradually. How to increase the success rate of construction once and improve the timeliness of construction and production This issue is also gradually placed in front of our operators. In view of this situation, this paper selected the red sand, note the two aspects of the author’s general construction experience, for your reference, and we work together to explore common progress.
