油田开发过程中,油管是维持油水井正常生产中必不可少的入井材料。随着油田开发逐步进入中后期,为了维持油水井的正常生产,每年都要投入大量的新油管将老化报废的油管替换出来。在油田产能逐年递减的严峻形势下,居高不下的油管投入成本严重制约了油田开发的效益产出。因此,如何最大限度的延长油管的使用周期,建立油管使用的良性循环,通过逐步减少油管材料成本的投入来达到降本增效的目的就成为了油田开发中后期所面临的主要问题。
Oilfield development process, tubing is essential to maintain the normal production of oil wells into the well of the material. As oilfield development gradually progresses into the middle and late stages, a large number of new tubing will be put into service to replace the aged scrapped tubing in order to maintain the normal production of oil and gas wells. Under the grim situation that oilfield production capacity decreases year by year, the high input cost of tubing has severely restricted the benefit output of oilfield development. Therefore, how to maximize the service life of tubing and establish a virtuous circle of tubing utilization, and achieve the purpose of cost reduction and efficiency increase by gradually reducing the investment of tubing material cost have become the major problems in the middle and later stages of oilfield development.
