Abstract

The invention discloses a whole-course visualized self-supporting fracturing technology study device. The device comprises following units of (1), a visualized variable slit width simulation self-supporting fracturing liquid distribution flow flat plate and pressure measuring unit; (2), a visualized clamping and temperature control unit; (3), a visualized liquid injection pipeline, shaft and blending equipment simulation unit; (4), a liquid supply unit; (5), a pressure control and flow control unit; (6), a self-supporting fracturing liquid and passageway fracturing liquid separator; and (7), an image acquisition unit. The units are combined together to form a flow space which has 10 MPa liquid pressure resistance and can simulate the flow distribution rule of a self-supporting fracturing liquid system in a perforation belt and a parallel crack space, meanwhile, the flow space is provided with a heating temperature control system, the heating conditions of a simulated formation can be provided, and self-supporting fracturing liquid distributed differently generates a phase change to form a self-supporting solid phase.

Description

technical field [0001] The invention belongs to the field of petroleum exploitation, in particular to the technical field of oil and gas production stimulation measures, and in particular to a whole-process visual self-supporting fracturing process research device. Background technique [0002] Facing the technical problems existing in the current volume fracturing technology, the slick water carries the quartz sand with a limited migration distance, the particle size of the added sand is extremely small, and the continuous operation is usually impossible. At present, a brand-new hydraulic fracturing process measure-liquid self-supporting fracturing technology has been developed. The technical principle is: use immiscible self-supporting fracturing fluid (no solid phase at room temperature, liquid with good flow ability, unique heat sensitivity, self-supporting solid phase will be generated when heated to a certain temperature) and Channel fracturing fluid (at room temperat...
