Embodiment 1

[0043] See Figure 1 to Figure 3 , The present invention provides a technical solution:

[0044] A test device for the permeability of consolidated sand, comprising a transparent glass 2 and a pipe 4, characterized in that both the transparent glass 2 and the pipe 4 are cylindrical. The pipe 4 can contain core samples. It also includes a rubber hose 3, which can be adjusted to any bending shape. The rubber hose 3 is used to connect the transparent glass 2 and the pipe 4. Valve 6 and valve 6 are used to control whether the water flow in the core sample in the pipeline 4 flows out. The measuring cylinder 7 and the measuring cylinder 8 are used for volume statistics of the water flow. The electronic control system 11 is used to control the opening and closing of the valve 6.

[0045] Preferably, the electronic control system 11 includes a waterproof sealed box, and the waterproof sealed box is equipped with a PLC controller 15, a battery 14, a timer 16, and a relay 17, and the bat...

Embodiment 2

[0065] Such as Figure 4 In this embodiment, on the basis of the above-mentioned embodiment, a rotating plate 9 is set to rotate at the bottom of the pipe 4 below the core sample. The rotating plate 9 can be rotated by the handle 10 provided on the outside of the pipe 4, which can easily adjust the water flow from the inlet The nozzle 1 falls into full contact with the core, and the rotating plate 9 can be rotated by the handle to control whether the water flow is blocked.

Abstract

The invention discloses a consolidated sand permeability testing device and test method. The device comprises transparent glass and a pipeline which are cylindrical, wherein rock samples can be accommodated in the pipeline; the device also comprises a rubber hose, a valve, a measuring cylinder and an electrical control system, wherein the rubber hose is used for connecting the transparent glass and the pipeline; the valve is used for controlling whether water flow in the rock samples in the pipeline flows out; the measuring cylinder is used for counting the volume of the water flow; the electrical system is used for controlling opening and closing of the valve. Actual field application is facilitated, the cost is low, and special fields for storage and operation by professionals are not required; in field practice, the test is rapid and simple; with the mode, requirements can be met; time control difficulty is low in the testing process.

Description

Technical field [0001] The invention relates to the technical field of oilfield sand control, in particular to a test device and a test method for the permeability of consolidated sand. Background technique [0002] Consolidated sand control is an important technology for oilfield sand control. Consolidated sand is generally cemented with quartz sand and chemical binders. The consolidated sand constructs a sand control barrier at the bottom of the well to block sand production from the formation and prevent formation sand from entering the pumping equipment and causing damage. [0003] The purpose of consolidated sand control is to retain sand and at the same time allow the formation fluid to enter the wellbore smoothly and then be produced to the surface. Therefore, the level of permeability is an important indicator for evaluating the quality of consolidated sand. At present, there are many methods for testing the permeability of consolidated sand. The gas permeability test use...
