Indirect method measuring oil well debit

Developed a new method determining oil well debit using measuring outlet flow temperature values. Proposed mathematical model allowing calculate temperature profile of the fluid along well-bore for determining oil well debit, taking into consideration geothermal gradient in the rock, surrounding the well-bore. It has been shown, that unlike the existing methods proposed the new method allowed very easily determined instantly oil well debit. Proposed new oil well debit measuring system allowed realize continuous monitoring and improve efficiency oil well work.
