METHOD OF WELL PRODUCTION OF LIQUID MINERAL SUSCEPTIBLE TO TEMPERATURE PHASE TRANSITION Russian patent published in 2009 - IPC E21B43/00 E21B37/00 

FIELD: oil and gas industry.

SUBSTANCE: invention refers to oil and gas industry, particularly to well production of liquid minerals. The method consists in pumping hot heat carrier via a closed circulation system formed by means of arrangement of an additional suspended process column between a conductor string and a producer connecting annular and interior spaces of the suspended process column and surface capacity and pump equipment after the principle of communicating vessels through a well head piping. To this purpose in the process of producer boring upon cementing the conductor string there is carried out well sinking for the suspended process column and further for the producing column; first the suspended, then producing columns are lowered; cement behind the producing column is lifted to depth of 50 m below a shoe of the suspended column; formed circulation system is immediately flushed. Further the producing reservoir is exposed; the producing column is protected from solid formations by means of thermostating owing to continuous or periodical pumping of hot heat carrier via the formed circulation system.

EFFECT: increased reliability of column protection and reduced costs.
