TWO-PHASE FLOW BEHAVIOR AND SPINNER DATA ANALYSIS IN GEOTHERMALWELLS

摘要

A method has been developed for interpretation ofrnPressure-Temperature-Spinner (PTS) surveys. Driftfluxrnand homogenous flow models are evaluated forrnapplication in two-phase flow in geothermal wells. Itrnwas found high fluid velocity makes possible simplernassumptions regarding holdup and friction losses.rnThe analysis method provides sufficient resolution torndetermine mass contribution and enthalpy ofrnindividual feed zones in geothermal wells. Techniquernis described and a field example provided.
