The invention relates to an oil-gas-water multi-phase flow adjusting apparatus, which mainly comprises an inlet accelerating pipe section, a vortex flow guide spiral pipe, a gas circuit exit connection pipe section, a liquid receiving cone, a mixed liquid relief exit connection pipe section and a sampler exit connection pipe section, and which has the function for changing at intervals the flow pattern, the flow state and the components of the oil-gas-water multi-phase flow. The invention also relates to an oil-gas-water multi-phase flow rate measuring apparatus and its measuring method. The measuring apparatus comprises a blind three-way mixing means, a pressure differential type flow measuring device, a single-&#x3b3; phase volume fraction meter, a dual-&#x3b3; phase volume fraction meter, an oil-gas-water multi-phase flow adjusting apparatus and a computing system. The measuring method is as follows: the single-&#x3b3; phase volume fraction meter and the dual-&#x3b3; phase volume fraction meter measure the gas content GVF and the water content WC respectively; the pressure differential type flow measuring device measures the differential pressure &#x394;P of the total flow rate; the computing unit computes the oil flow rate Qo, the gas flow rate Qg and the water flow rate Qw.

Oil-gas-water multi-phase flow adjusting apparatus and oil-gas-water multi-phase flow rate measuring apparatus and measuring method

An adjustable type guide vortex gas-liquid separating apparatus is provided, it comprises a case, a vortex flow guide spiral pipe, a mist eliminator, an adjusting valve and a &#x3b3; ray phase volume fraction meter. Its separating method is to make the oil-gas-water multiphase flow move in vortex, and thus to realize the gas-liquid separation, then to measure the gas content of the separated liquid phase by using the &#x3b3; ray phase volume fraction meter and to send out control information as judged by the magnitude of the gas content in the liquid phase, so as to control the opening of the adjusting valve of the gas circuit, thus to achieve adjustment of the gas-liquid separation effects, and to control the gas content of the liquid phase to a certain range.
