Abstract
Ensuring the fire and blowout safety for oil and gas wells is currently a central task while hydrocarbons field development. It is particularly important during new oil and gas reserves exploration in remote areas in severe climate (arctic) conditions. In this case in the absence of reliable geological data of exploration objects the problem of blowout safety becomes very significant not only during the drilling process but also during the tests of all available formations. In the article the reasons of frequent blowouts and open burning blowout liquidation techniques with the use of present-day technical equipment applied on a real blowing well are considered. Initially on the burning wellhead the operation of cutting and taking to pieces of drilling rig metal construction was made with the help of mobile laser technological system. In the fire flame by means of laser cutting the base for shut-off valves targeting was prepared. After that, on the burning wellhead the shutdown assembly was applied with the help of the wire system; due to this assembly the burning flame was removed from the wellhead on a safe altitude. Further the well control equipment was installed on the wellhead under the burning flame, the well was killed and the fire was put out.
