The Oil-water Well Snubbing Capillary Delivery Pressure Transmission Technology

The oil-water well snubbing operation has the advantage of technology for reservoir protection,reducing overflow discharge,Protect environment etc.,Shengli Oilfield snubbing operation task is increasing year by year in recent years.While the conventional snubbing cast plugging technology exist multiple construction processes,low efficiency,higher costs,has been unable to meet the increasing amount of construction task,restricted the further promotion of snubbing operation technique,to solve the traditional column cast plugging technology in the existing problems,development of oil well snubbing homework capillary delivery technology research.The technology realization by capillary plugging device allocation and seat sealing,delivery pressure integration,high construction efficiency,low cost.The use of the working principle of well testing winch drive roller,through capillary delivery plug,delivering accurate position.Through the capillary pressure seat sealing plug,the construction process will not cause pollution in reservoir.The technology can effectively shorten the snubbing pipe plugging construction time,the construction cycle is the traditional investment and plugging technology is shortened by 87.1%,the site promotion in 1268 wells,effectively reduce the formation pollution,improve the production effectiveness,saving cost of vehicle use,has provided the powerful technical support for snubbing operation in a step large-scale popularization and application.
