Description

Technical Field

[0001] The utility model relates to the technical field of drilling fluid, in particular to a high-temperature and high-pressure filtration loss detection device for drilling fluid. Background Art

[0002] The drilling fluid high temperature and high pressure filter loss detector, also known as the high temperature and high pressure filter loss instrument, is an instrument specifically used to test the filter loss performance of drilling mud under high temperature and high pressure environment. The instrument is usually composed of a main body (including base, column, heating system and other components), a three-way component (used to connect the gas pipeline and the connecting valve stem to release the remaining gas in the manifold system), a slurry cup and a back pressure receiver component. By simulating the high temperature and high pressure environment downhole, the instrument can measure the filter loss of mud under this condition and simultaneously prepare the filter cake formed after the filter loss, thereby helping engineers understand and optimize the mud formula and improve drilling efficiency and safety;

[0003] During use, the slurry cup containing the drilling fluid needs to be placed inside the heating component of the main unit. After the detection is completed, it needs to be manually pulled out. The slurry cup is relatively heavy after containing the drilling fluid, and it is difficult to pull it out. In addition, the slurry cup needs to be heated during the detection process, so the temperature of the slurry cup is relatively high. There is a risk of scalding when it is manually pulled out. Therefore, the utility model proposes a drilling fluid high-temperature and high-pressure filtration loss detection device to solve the problems existing in the prior art. Summary of the invention

[0004] In view of the above problems, the utility model proposes a drilling fluid high-temperature and high-pressure filtration loss detection device. The drilling fluid high-temperature and high-pressure filtration loss detection device does not require manual force and is more convenient to use. After being ejected to a certain distance, this section of the drilling fluid cup is no longer in contact with the heating sleeve, and the heat dissipation is faster. It is convenient to take it away after it cools down, avoiding the risk of scalding.

[0005] To achieve the purpose of the utility model, the utility model is implemented by the following technical solutions: a drilling fluid high temperature and high pressure filtration loss detection device, comprising a main unit and a drilling fluid cup, a heating sleeve is provided at the middle position inside the main unit, the drilling fluid cup is inserted into the interior of the heating sleeve from above, and a first leg and a second leg are respectively provided on both sides of the bottom of the main unit;

[0006] A movable sleeve is movably provided inside the first leg, a guide groove is provided on one side of the first leg, a push block is provided on one side of the movable sleeve, and the push block passes through the guide groove, a push rod is provided above the push block, and the upper end of the push rod movably passes through one side of the bottom of the heating sleeve, the upper end of the push rod is supported on the bottom of the drilling fluid cup, a threaded screw is rotatably provided inside the first leg, and the movable sleeve is threadably adapted to the threaded screw.

[0007] A further improvement is that an upper joint is installed on the top of the drilling fluid cup through an end cover, a lower joint is installed on the bottom of the drilling fluid cup through an end cover, and a through hole for the lower joint to pass through is provided at the middle position of the bottom of the heating sleeve.

[0008] A further improvement is that a controller is provided on one side of the main unit, and the controller is electrically connected to the heating sleeve.

[0009] A further improvement is that a temperature-resistant gasket is provided at the upper end of the push rod, and the temperature-resistant gasket is supported on the bottom of the drilling fluid cup.

[0010] A further improvement is that a scale line is provided on the first leg at one side of the guide groove, and the scale line is used to indicate the height of the push block.

[0011] A further improvement is that a base is provided below the second leg, and a motor compartment is provided between the base and the first leg.

[0012] A further improvement is that a reduction motor is provided inside the motor compartment, and an output end of the reduction motor is connected to the threaded screw.

[0013] The beneficial effects of the utility model are:

[0014] 1. The utility model allows the drilling fluid cup to be inserted through the heating sleeve in the main machine and heated for detection. When the drilling fluid cup needs to be taken out after the detection, it is only necessary to drive the threaded screw to rotate, and cooperate with the guiding effect of the push block and the guide groove to drive the push block and the push rod to move upward, support the bottom of the drilling fluid cup, and push the drilling fluid cup out without manual force, which is more convenient to use. After being pushed out to a certain distance, the drilling fluid cup at this section is no longer in contact with the heating sleeve, and the heat dissipation is faster. It is convenient to take it out after it cools down, avoiding the risk of scalding.

[0015] 2. When the push rod of the utility model lifts up the drilling fluid cup, the heat-resistant gasket is supported between the push rod and the drilling fluid cup to avoid wear.

[0016] 3. In the process of the push block moving and driving the push rod to lift, the height of the push block can be observed through the scale line, which is convenient for controlling the ejection distance and avoiding the drilling fluid cup being completely ejected from the heating sleeve and falling off.
