METHODS AND APPARATUS FOR MAKING MEASUREMENTS ON FLUIDS PRODUCED FROM UNDERGROUND FORMATIONS

摘要

Methods for making measurements on fluid produced from a formation into a borehole include the steps of isolating an interval of the borehole from the rest of the borehole; drawing fluid from the formation through the isolated integral at a rate close to normal for that formation, and measuring parameters of the formation fluids flowing through the isolated interval apparatus for performing such methods have a tool body with a flow passage, packers mounted on the tool body for isolating an interval of the borehole, a pump for drawing fluid from the formation in the interval and through the flow passage at rates close to normal production rates for that formation, and a suite of one or more sensors for measuring the fluids as they pass through the flow passage.
