油气集输管道是油田的生命线,在冀东油田目前保持陆上产能稳定、大力开发海上产能的形势下,如何开展管道的维修工作,保证油田生产活动的安全正常进行对我们意义重大。不停输带压封堵技术的使用为我们提供了一个在管道不停输状态下处理油气管道穿孔等问题的方法。在冀东油田,不停输带压封堵技术还处于初始状态,但是通过近几年的实际应用,我们通过分析解决实际操作中遇到的问题,不断总结经验,使得冀东油田在这项技术的应用上取得了很大的进步。同时,针对目前冀东油田滩海及浅海油气田开发的形势,引进海管维修技术已成为必要,本文通过对目前行业内较成熟的海管维修技术的特点分析并根据冀东油田的实际情况,发现水上焊接维修技术比较适合冀东油田的发展形势。因此,我们要做的就是完善目前已掌握的不停输带压封堵技术,并发展以不停输带压封堵为主的陆上管道维修技术体系,引进水上管道焊接维修技术并逐步建立起滩海及浅海管道维修力量。
As oil and gas pipelines are the lifeblood of oilfields, it is of great significance to us how to carry out pipeline maintenance work and ensure the safety of oilfield production activities under the current situation that Jidong Oilfield maintains the onshore production capacity stability and vigorously develop offshore production capacity. The use of non-stop pressure seal technology provides us with a way to deal with problems such as perforation of oil and gas pipelines while the pipe is not running. In Jidong Oilfield, non-stop pressure belt sealing technology is still in its infancy, but through the practical application in recent years, we analyze and solve practical problems encountered in the operation, continue to sum up experience, making Jidong Oilfield in this The application of technology has made great progress. At the same time, in view of the current situation of the development of the beach sea and the shallow sea oil and gas fields in Jidong Oilfield, it is necessary to introduce the sea-tube maintenance technology. Based on the characteristics of the mature sea-tube maintenance technology in the present industry and according to the actual situation of Jidong Oilfield, Found that water welding repair technology more suitable for the development of Jidong Oilfield situation. Therefore, what we need to do is to perfect the technology of non-stop pressure transmission and sealing which we have now, and to develop a technical system for onshore pipeline maintenance based on non-stop pressure and pressure blockage, and introduce the water pipe welding and maintenance technology and gradually establish From the beach and shallow sea pipe maintenance force.
