The invention discloses a comprehensive experimental device for levelly and evenly distributing acid, which belongs to the petroleum exploitation field. The experimental device consists of two sections of oil pipes and a sleeve; the two sections of oil pipes are packed by an expanding packer, and the two sections of oil pipes is covered with a sleeve; a gap is left between the oil pipe and the sleeve; the two sections of oil pipes and the sleeve are respectively provided with a minisize flux control valve; the two sections of oil pipes are respectively provided with a flow meter; the two endsof the sleeve which corresponds to the two sections of oil pipes are respectively provided with a pressure gauge. The operation method includes measuring the liquid pressure at the two ends of the sleeve and the flux in a certain period, then feeding back the measured results to the real products, and choosing corresponding minisize flux control valve combination according to the permeability of the base. The device can simulate the heterogeneity characteristics of the oil reservoir in the real oil field and reasonably distribute the minisize flux control valve on the acid pipe according to the permeability in order to realize the purpose of even acid distribution and even acidification by the level and even acid distribution pipe.
Description
technical field [0001] The invention relates to an experimental device for distributing acid used in the field of petroleum exploitation and an operating method thereof, in particular to a comprehensive experimental device for distributing acid horizontally and uniformly used in the field of petroleum exploitation and an operating method thereof. Background technique [0002] In the process of oilfield development, according to the needs of oilfield adjustment, transformation, improvement, and potential tapping, and in accordance with the requirements of process design, a set of surface and downhole equipment and tools are used to take various downhole technical measures for oil and water wells to increase injection and production. The purpose of improving the seepage conditions of the oil layer and the technical status of oil and water wells, increasing the oil recovery rate and the ultimate recovery rate. This series of downhole construction techniques are collectively ref...
