Embodiment 1

[0030] Embodiment one, see figure 1 , a tester for detecting the liquid resistance height of the proppant of the present invention, the tester includes:

[0031] The first liquid storage tank 101, the inside of the first liquid storage tank 101 is provided with a thermometer 106 for measuring the temperature of the test liquid in the first liquid storage tank 101; The liquid level indicator 107 is used to display the liquid level in the first liquid storage tank 101 . A thermometer 106 is set in the first liquid storage tank 101 to obtain the temperature of the test liquid, so as to measure the liquid resistance performance of the proppant to test liquids of different temperatures; a liquid level indicator 107 is set to display the temperature of the first liquid storage tank 101, in order to timely adjust the liquid level height in the first liquid storage tank 101, to avoid the liquid level is too high test liquid overflow or the liquid level is too low to pump gas into the...

Embodiment 2

[0046] Embodiment two, see figure 2 Shown:

[0047] A tester for detecting the liquid blocking height of the proppant of the present invention comprises:

[0048] The second liquid storage tank 205, the outer wall of the second liquid storage tank 205 is made of transparent material, and the height scale is engraved on the outer wall, the liquid storage volume in the second liquid storage tank can be observed in real time, so as to adjust in time The amount of liquid stored in the second liquid storage tank 205 is to prevent the liquid level in the second liquid storage tank 205 from overflowing when the liquid level in the second liquid storage tank 205 is too high or the gas injected into the measuring device when the liquid level is too low.

[0049] A liquid inlet device, the liquid inlet device is provided with a valve 206 and a liquid outlet pipe 204, and the liquid outlet end of the liquid outlet pipe extends into the vicinity of the top of the charging part. The liq...

Abstract

The invention relates to a tester used for testing fluid resistance height of a proppant and a testing method thereof. The tester comprises a measuring device, a fluid level sensor and a processer, wherein the measuring device comprises a material containing part used for containing a to-be-measured proppant and a fluid containing part used for containing testing fluid, the fluid containing part is communicated with exterior, and the material containing part is made of dewatering materials; the fluid level sensor is used for being embedded at a position near the upper surface of the to-be-measured proppant; and the processer is used for receiving signals sent by the fluid level sensor and obtaining the height, namely, the fluid resistance height of the testing fluid contained in the fluid containing part when the fluid level sensor senses the testing fluid. According to the tester used for testing the fluid resistance height of the proppant, simulation of formation conditions is not needed, the fluid resistance height of the testing fluid passing through the proppant with scheduled filling thickness can be tested visually under the ordinary pressure condition, and therefore the fluid resistance performance of the proppant can be estimated visually and accurately. Different proppants have different fluid resistance heights under the same testing condition, the higher the values of the fluid resistance heights are, the better the fluid resistance performance is, and the lower the values of the fluid resistance are, the worse the fluid resistance performance is.

Description

technical field [0001] The invention relates to a liquid-blocking performance testing device and a method of a proppant, in particular to a tester for detecting the liquid-blocking height of a proppant and a testing method thereof. Background technique [0002] In the development process of oil and gas wells, due to the continuous decline of formation pressure, the edge water advances and the bottom water rises. In addition, fracturing, acidification, water injection and other production and injection operations increase the oil and gas water content of oil and gas wells, even reaching 90. % or more, which not only reduces the production efficiency, but also sharply increases the amount of sewage treatment in oil and gas fields, consuming a lot of manpower and material resources. The proppant with selective liquid blocking properties is a material with water blocking properties that is injected into the formation during the fracturing process to support fractures and improve...
