目前,国内大部分的油田已经进入到了开发的中后期,随着油水井工作时间的增加,油水井在开发过程中出现的问题也越来越多,其中套管的损坏问题是油水井开发过程中出现的主要问题之一,套管的损坏严重的影响了油水井的正常作业,而且套管的破损的影响了油田井网完整性,造成了层与层之间的流通和油层能量的损失。套管的损坏影响的了油水井的正常运行,降低了油藏采收率,造成了能源的浪费。因此研究新型油水井修井技术势在必行,文章通过文献调研和理论分析,研究分析了实体膨胀管补贴修井技术、套管补贴水泥加固修井技术、等新型修井技术,为修补油水井破损套管,恢复正常生产,进一步提供油田的开发水平奠定了基础。
At present, most of the domestic oilfields have entered the middle and late stages of development. As the working hours of oil and water wells increase, there are more and more problems in the development of oil and water wells. The damage of casing is the development process of oil and water wells One of the main problems that occurred was that the casing damage seriously affected the normal operation of oil and water wells and the casing damage affected the well pattern integrity of the oilfield and resulted in the circulation between layers and the loss of reservoir energy . The damage to the casing affected the normal operation of oil and water wells, reducing oil recovery and resulting in energy waste. Therefore, it is imperative to study the new oil well workover technology. Through literature research and theoretical analysis, the article studies and analyzes the physical expansion pipe subsidy workover technology, casing subsidy cement reinforcement workover technology, and other new workover techniques, Wells damaged casing, to resume normal production, to further provide the level of development of the oil laid the foundation.
