Description

Technical Field

[0001] The utility model relates to the technical field of filter loss instruments, in particular to a filter loss instrument for non-permeable drilling fluid. Background Art

[0002] During oil exploration or oil production, foreign fluids come into contact with different formations and fluids in the well, which can easily cause damage to the oil and gas layers. Reservoir damage not only affects the initial production of the oil well, but also affects the degree of damage and the effect of subsequent operations. In order to protect the oil and gas layers and avoid reservoir damage, it is necessary to consider reducing the intrusion of drilling fluid into the reservoir. Oil workers hope to develop drilling fluids that are non-invasive to the reservoir and protect the oil and gas layers, so non-permeable drilling fluids are used. Non-permeability means no liquid and solid phase intrusion damage, so non-permeability drilling fluid loss meters are needed;

[0003] For example, Chinese patent CN206369730U discloses a filter loss tester for non-permeable drilling fluid. The hydraulic rod of the device cooperates with the pressure plate to flatten the sand in the inner tube, which not only saves manpower but also has better effects. During experimental observation, the rotating frame can rotate to place the hydraulic rod on the side of the support plate to avoid interference with the work of other parts.

[0004] However, there are certain defects in this patent. The device flattens the sand in the inner tube through a pressure plate. At this time, the pressure plate and the inner tube are in a vertical state. After the operator rotates the rotating frame, there is no limit device in the device, and the rotating frame cannot be quickly limited. When the rotating frame is adjusted to its original position, a small angle deviation may occur, resulting in certain limitations when the device is used. Utility Model Content

[0018] The utility model provides a non-permeable drilling fluid loss instrument, which has the following beneficial effects:

[0019] (1) According to the utility model, after the operator flattens the sand on the inner wall of the pipe through the pressure plate, the position of the support block can be rotated. First, the operator can pull the position of the handle, and move the handle between the limit block, the plug rod, the extrusion spring, the support block, the rotating block, the top plate, the cylinder and the pressure plate, so that the pressure plate and the cylinder do not affect the operator's use of other components, and the operator is convenient for quickly moving the position of the pressure plate.

[0020] (2) In the utility model, when the side wall of the limit block contacts the side wall of the support block, the limit block can stabilize the position of the support block, so that the pressure plate is located directly above the pipe and is not prone to deviation, which facilitates the pressure plate to squeeze the sand better and solves the problem of the device flattening the sand in the inner pipe by the pressure plate. At this time, the pressure plate and the inner pipe are in a vertical state. After the operator rotates the rotating frame, the device is not provided with a limit device, and the rotating frame cannot be quickly limited. When the rotating frame is adjusted to its original position, a small angle deviation may occur, resulting in certain limitations when the device is used. BRIEF DESCRIPTION OF THE DRAWINGS

The four pads 2 are fixedly mounted at the four corners of the bottom of the fixed plate 1. The position of the device can be supported by the pads 2 at the bottom of the device.

[0031] and a processing assembly 4 disposed on the side wall of the fixed plate 1;

[0032] The processing assembly 4 includes an adjustment mechanism 41 installed at a side wall position of the fixed plate 1, and the adjustment mechanism 41 is located at a top position of the fixed plate 1;

[0033] A processing mechanism 42 is installed on the side wall of the fixing plate 1 , and the processing mechanism 42 is located at the bottom of the adjusting mechanism 41 .

[0034] The adjusting mechanism 41 includes a rotating block 415, which is fixedly mounted on the inner wall of the U-shaped plate 3. A support block 414 is rotatably mounted on the side wall of the rotating block 415. A top plate 411 is fixedly mounted on the top of the support block 414. A cylinder 412 is fixedly mounted on the bottom of the top plate 411. The cylinder 412 is installed with a pressure plate 413 through a telescopic rod at the output end. A limit block 416 is slidably mounted on the side wall of the support block 414. An insert rod 419 is slidably mounted on the inner wall of the limit block 416. An extrusion spring 418 is fixedly mounted on the inner wall of the limit block 416. The other end of the extrusion spring 418 is fixedly connected to the side wall of the U-shaped plate 3.

[0035] In this embodiment, the side wall of the limit block 416 is slidably connected to the inner wall of the U-shaped plate 3, the other end of the insertion rod 419 is fixedly installed with a pull block 4110, and the side wall of the limit block 416 is fixedly installed with a handle 417, which facilitates the operator to move the position of the limit block 416.

[0036] Furthermore, there are two limit blocks 416 , the two limit blocks 416 are equal in shape and size, and the two limit blocks 416 are symmetrically arranged relative to the middle surface of the U-shaped plate 3 in the left and right directions.
