ABSTRACT

The conveying characteristic of a twin-screw multiphase pump (MPP) boosting oil and gas is investigated experimentally regarding the dissolving and degassing phenomena that occur due to changes of pressure alongside the flow. The gas volume flow within the total volume flow increases as a result of pressure drops in the oil field, well and pipework before the suction side and decreases because of the pressure difference boosted by the MPP. Different gas volume fractions and flow patterns are measured by an electrical capacitance tomography (ECT) system. The operation quantities of the MPP, affected by the gas volume flow fraction, the pressure difference and the rotational frequency are determined according to thermodynamics.
