METHOD AND APPARATUS FOR THE DOWNHOLE METERING AND CONTROL OF FLUIDS PRODUCED FROM WELLS

摘要

In broad aspect, the underground metering of the method for the present invention and equipment and control fluid are injected into stratum, and include: shell (12) is hermetically connected to oil pipe; A kind of turbine meter setting offer instruction flow velocity in shell (18) flows through the surface of control panel; With in a variable orifice valve tool outer casing (24) which alternately allow, forbid, throttle fluid flows through. The system has a communication link to surface, vehicle mounted electric motivation (35) carries out drive hydraulic system principle and controls variable orifice threshold means (24) and the system of the throttling action in shell (12) to monitor and report down-hole pressure and temperature. The system selected commutation action to monitor from above-mentioned turbine producing formation.
