DEVICE FOR WELL OPERATION Russian patent published in 2008 - IPC E21B43/24 E21B36/04 

FIELD: mining.

SUBSTANCE: device contains flow column (FC) containing sections of FC, heaters in the capacity of which are used m sections of flow column. Sections of column are implemented as heated and mounted in points of flow column where temperature of well production is higher, e.g. for 5-10 degrees, minimally-allowable temperature- temperature at which it is possible well production fluidity loss. To the end of heated sections (HS) there are welded on centralizers. In top centralizer of each HS there is located connector. Device also contains m-channeled electric power package (EPP), instrumentation-control unit (ICU) with control output and with instrumentation outputs which are connected appropriately to firsts, seconds ... and m-s outputs of EPP. To the control inputs of EPP there are connected control outputs ICU. Outputs of EPP from the first till m are joined into supply cable. Zero output of EPP is connected to zero output of ICU and with c flow column. On the external surface of each tube of heated section under top centralizer there is fixed temperature sensor. Each supply cable conductor is connected through appropriate electrical connection to the feeding input by means of appropriate HS and to the input of appropriate temperature sensor input of which is connected to the HS tube. There is made an example of HS implementation.

EFFECT: increasing of well production output and expansion of method field of application.
