Problems solved by technology
The main problem is that it can only simulate the flow characteristics of oil-water two-phase flow in a single pipeline, and cannot test the flow change law of oil-water two-phase flow in the oil-gathering process of star-shaped pipeline network and the oil-gathering process of branched pipeline network , and it is impossible to test the distribution characteristics of the main pipe to each branch pipe

The invention discloses a testing device for flow characteristics of an oil-water two-phase flow, which adopts three mixing tanks to prepare oil-water mixtures with different oil-water ratios and is used for simulating the oil-water mixtures extracted from different oil wells. The device is provided with three pipelines which are respectively connected with three mixing tanks through centrifugal pumps, different positions of the three pipelines are mutually connected through valves and pipelines, and a star-shaped pipe network oil collection flow, a branch-shaped pipe network oil collection flow and a process of shunting from a main pipe to branch pipes can be simulated by controlling the opening and closing states of the valves. The pipelines are transparent organic glass tubes, so that the flowing state of fluid in the pipelines can be displayed in real time. Compared with an existing oil-water two-phase flow flowing characteristic testing device, the oil-water two-phase flow flowing characteristic testing device has the advantages that the oil-water two-phase flow flowing characteristic testing device can simulate a star-shaped pipe network oil collecting process, can simulate a branch-shaped pipe network oil collecting process, can test the flow dividing characteristic from a main pipe to all branch pipes, can simulate oil well products of different oil-water ratios, and is visual in fluid flowing state, rich in function, changeable in process and the like.
Description
technical field [0001] The invention relates to the technical field of flow characteristics of oil-water two-phase flow, in particular to a testing device for the flow characteristics of oil-water two-phase flow. Background technique [0002] In an oil field production block, many oil wells are distributed irregularly. The task of the oil field gathering and transportation station is to collect the output of all oil wells in the block to the combined station for unified processing, and there are many kinds of oil well gathering and transportation methods. At present, oil well gathering and transportation methods mainly include single well truck pulling, star pipe network oil gathering, branch pipe network oil gathering, annular pipe network oil gathering and so on. According to the specific environmental characteristics of the oilfield, the way of gathering and transportation is different, and the connection form between oil wells is also different. Due to the different ra...
