PendingCN122283056AQuantitativeRealize batchingThermodynamicsFracturing fluid
This invention discloses a device and method for evaluating the proppant-carrying performance of fracturing fluid with continuously adjustable proppant concentration, relating to the field of oil and gas field production enhancement. The device includes a reactor body. The reactor body is equipped with a stirring assembly, a proppant-adding assembly, a heating assembly, and a visualization window. The proppant-adding assembly achieves quantitative and batch-wise addition of proppant within the high-pressure reactor through a series of upper valves, a proppant-to-be-added section, and a lower valve. The method includes: applying experimental temperature and pressure conditions, initiating stirring to simulate dynamic flow, continuously adding proppant in batches through the proppant-adding assembly, monitoring the proppant status in real time using a vision system, and recording and analyzing data to obtain a continuous proppant-carrying performance curve and a limit proppant-carrying value. This invention solves the problem of existing technologies being unable to conduct continuous gradient testing of proppant concentration under high-temperature and high-pressure dynamic conditions, and can obtain complete proppant-carrying performance data of fracturing fluid from low concentration to limit concentration in one go, with evaluation results closer to actual downhole operating conditions.
