Fixed sealing tech by paraffin for well head of wire-line read out testing and oil recovery

Abstract

During developing period of the oilfield, some wells need a long term to test, especially for wells of acquiring data of oil testing and recovery. When monitoring formation pressure by read-out electronic gauge, it is a technical problem to settle that the sealing condition of signal line at well head is not good. Firstly, fixed sealing tech by paraffin for well head of wire line is using compressed sealing colloid out of wire-line for testing voltage to seal primarily at the two ends. And then, melt liquid wax is inject in inner body and high pressure is made to make the liquid wax penetrating clearance between outer steel line of wire line and outer insulated skin of the core line that seals the wire-line at well head for acquiring pressure properly when high pressure liquid wax is solidified. The method and process of it is illustrated which has a valuable effect.
