Problems solved by technology

At present, the fracture initiation and propagation in hydraulic fracturing can generally be studied through indoor experiments and numerical simulations, but there is no effective experimental measurement method for the proppant laying law in fractures. Currently, internal fractures cannot be detected, and only Simulation by Numerical Methods

Abstract

The invention relates to a device and a method for measuring distribution of proppants in rock strata. The device is characterized by comprising a cylindrical shell with the upper end open, an end cover, a control and processing device, a plurality of hollow supporting bodies with two ends open and fluxgate sensor mounting seats as many as the hollow supporting bodies. The end cover is fixedly arranged at the top of the shell, at least three connecting holes communicated with the inside of the shell are formed in the top of the end cover at intervals, the supporting bodies are arranged on the outer side face of the shell circumferentially and longitudinally at intervals, one fluxgate sensor mounting seat is fixedly arranged inside every supporting body, a plurality of fluxgate sensors are fixedly arranged in every fluxgate sensor mounting seat, and every fluxgate sensor is connected with the control and processing device. The device and the method for measuring distribution of the proppants in the rock strata can be widely applied to measurement of distribution conditions of the proppants in the rock strata.

Description

technical field [0001] The invention relates to a device for measuring proppant distribution in rock formations and a measuring method thereof, belonging to the technical field of oil and gas exploration. Background technique [0002] As the oil and gas exploration and development targets gradually shift from traditional oil and gas reservoirs to unconventional oil and gas reservoirs, hydraulic fracturing technology has become a key technology in the efficient development of oil and gas. [0003] In hydraulic fracturing construction, the distribution of proppant in fractures is an important factor affecting the conductivity of fractures, so it has attracted much attention. At present, the fracture initiation and propagation in hydraulic fracturing can generally be studied through indoor experiments and numerical simulations, but there is no effective experimental measurement method for the proppant laying rules in fractures. Currently, internal fractures cannot be detected, ...
