Device for simulating cleaning portable visual propping agent sinking law

Abstract

The invention discloses a device for simulating a cleaning portable visual propping agent sinking law. The device comprises a porous transparent panel, silica gel rings and an outer frame, wherein theporous transparent panel is mounted in the outer frame; the silica gel rings are mounted on the four sides of the porous transparent plate and are tightly pressed by the inner sides of the outer frame; the outer frame is formed by oppositely attaching two metal frames which have rectangular structures; a sealing washer is arranged in an attaching surface and serves as 1# sealing washer; elongatedgrooves with the same sizes are separately arranged on two narrow sides of the attached outer frame and separately serve as a fracturing fluid inlet and a fracturing fluid outlet; an elongated grooveis formed in the bottom of the attached outer frame and serves as a bottom cleaning outlet; fixing hooks are separately arranged on the outer surfaces of the two sides, which are close to the bottomcleaning opening, of the outer frame; the bottom cleaning outlet is provided with a bottom sealing plate of which the size corresponds to the size of the bottom cleaning outlet; and a movable hangingring and a hasp lock are separately arranged on the two sides of the bottom sealing plate. After an experiment is finished, cleaning becomes rapid and thorough so as to bring convenience for an experiment next time.

Description

Technical field [0001] The invention relates to the technical field of oil and gas field development, in particular to a cleaning, convenient and visualized proppant settlement law simulation device. Background technique [0002] With the development of the world economy, the reliance on and demand for oil has increased. The production and reserve-production ratio of conventional oil reservoirs are showing a decreasing trend. The exploration and development of low-permeability oil reservoirs has received attention as an energy supplement. . Hydraulic fracturing plays a very important role in the stimulation and development of low-permeability oil fields. The high conductivity fractures formed by fracturing not only determine the stimulation and injection capacity of oil-water wells after fracturing, but also affect the reservoir The recovery factor during the dry period and the ultimate recovery factor. In the process of hydraulic fracturing, due to factors such as fracturing f...

AI Technical Summary

Problems solved by technology

[0003] Although the existing experimental simulation devices have simulated the proppant laying process well to a certain extent, these devices currently have the common problem of difficult cleaning. After the experiment, the proppant and liquid remain in many dead corners of the device. The fracture width is relatively narrow, and some fracturing fluids have high viscosity, so that the proppant particles and the high-viscosity liquid are cemented into a block and remain in the dead corner of the bottom of the device. It is difficult to clean it out by ordinary cleaning methods, which greatly affects the experimental process and experimental results.
