Description

Technical Field

[0001] The utility model belongs to the technical field of filter loss instruments, in particular to a double filter loss instrument. Background Art

[0002] Drilling fluid is an indispensable material in drilling. It can lubricate drill tools, cool the drill bit, and carry cuttings during the drilling process. During oil drilling, controlling the filtration loss of drilling fluid is of great significance to protecting the shale well wall and improving drilling efficiency. Drilling fluid mud is the most commonly used drilling fluid, and different mud drilling fluids need to be measured using a filtration loss meter in order to develop better quality drilling fluids.

[0003] The existing drilling fluid loss meter has a single function and cannot test two or more different samples at the same time and under the same conditions. It cannot directly compare the loss performance of different drilling fluids and can only be tested one by one. The different test time and environment can easily lead to test errors. For this reason, we propose a dual loss meter.

[0004] It should be noted that the above content belongs to the scope of technical cognition of practical people and does not necessarily constitute prior art. Utility Model Content

[0005] In order to solve the above problems, the utility model aims to provide a dual filter loss tester, which has the advantages of being able to perform comparative tests on different drilling fluid samples and improving the reliability of the test results.

[0006] To achieve the above-mentioned purpose, the utility model proposes a double filter loss instrument, including a bottom plate, two brackets are symmetrically fixed on the top of the bottom plate, an upper plate and a lower plate are respectively fixed between the two brackets, two filter cups are symmetrically placed on the top of the lower plate, and two threaded holes with consistent threads are symmetrically opened on the top of the upper plate, screws are threadedly connected in the two threaded holes, the bottom ends of the two screws are rotatably connected to sealing covers through pin shafts, the two sealing covers are respectively in close contact with the tops of adjacent filter cups, heating components are arranged on the two sealing covers, and pressurizing components are arranged on the two brackets.

[0007] Preferably, the heating assembly comprises a heater fixed on the top of the sealing cover, a heating tube is fixed to the bottom end of the heater, and the bottom end of the heating tube passes through the bottom of the sealing cover and is located in the filter cup.

[0008] Preferably, a temperature sensor and an audible and visual alarm are respectively fixed to the top of the sealing cover, and a detection end at the bottom of the temperature sensor is located in the filter cup.

[0009] Preferably, the pressurizing assembly includes an air pipe fixed between the top ends of the two brackets, and two air outlets are arranged on the surface of the air pipe. Both air outlets are fixedly connected with hoses, and the bottom ends of the two hoses are respectively connected to the tops of adjacent sealing covers.

[0010] Preferably, a slide rod is fixed on the top of the sealing cover, and two slide holes matched with the slide rod are respectively opened on the top of the upper plate, and the top ends of the two slide rods pass through adjacent slide holes and are fixed with limit blocks.

[0011] Preferably, the bottoms of the two filter cups are fixedly connected to a discharge pipe, and the surface of the lower plate is symmetrically provided with two grooves, and the two grooves are adapted to the discharge pipe.

[0012] The double filter loss instrument proposed by the utility model can bring the following beneficial effects:

[0013] In the utility model, by setting a heating component and a pressurizing component, the tester sets the pressure value on the pressurizing component, so that the pressure in the two filter cups can be consistent. The personnel can set the heating values ​​of the two heaters through the controller, and the temperature in the two filter cups can be kept consistent, so that the same high temperature and high pressure environment can be simulated in the two filter cups, so that the two samples can be compared and tested more accurately, the error of drilling fluid testing can be reduced, and the accuracy of data can be improved.
