带压作业技术是指在井筒有压力的情况下,通过带压作业装置进行起下管柱作业,不降低地层压力的井下作业工艺,是解决低压油水井由于作业过程井漏造成产量恢复周期长的有效方法。近年来,我厂注水井带压作业数量呈逐年上升趋势,而带压作业成本较高,本文结合带压作业的意义、技术特点及与常规作业应用情况的对比结果,对葡萄花油田是否有必要进行带压作业进行探讨。并围绕如何确定带压作业应用范围,有效发挥带压作业的优势,降低作业成本提出几点建议。
With pressure in the wellbore technology refers to the case of pressure in the wellbore, with the pressure from the operating device for the next column operation, does not reduce the formation pressure downhole operation process is to solve the low-pressure oil wells due to the operation of the process caused by leakage of production recovery cycle length Effective method. In recent years, the number of injection wells with injection wells in our factory has been increasing year by year, and the cost of pressure-bearing operations is relatively high. Based on the significance of the pressure-stripping operation, the technical characteristics and the comparison with the conventional application, Necessary to carry out pressured operation to explore. And put forward some suggestions on how to determine the application scope of belt pressing work, effectively bring into play the advantages of belt pressing work, and reduce the work cost.
