Description

Technical Field

[0001] This utility model belongs to the field of geological logging technology, specifically, it relates to a device for collecting rock cuttings. Background Technology

[0002] During oil extraction, formation fluids are returned to the surface along with drilling fluid. Due to the high formation pressure, the returned fluids need to undergo gas-liquid separation. The processed liquid phase and rock cuttings enter a buffer tank via pipeline, and are then further processed by a vibrating screen. Because the buffer tanks vary in height, and most are quite tall, most of the rock cuttings entering the tank settle at the bottom and cannot be returned. Logging personnel need to retrieve the rock cuttings from the buffer tank. During this retrieval process, the logging personnel are positioned above the buffer tank, posing a risk of falling in. Utility Model Content

[0003] One objective of this invention is to provide a device for collecting rock cuttings, so as to facilitate logging personnel in collecting rock cuttings, improve rock cuttings collection efficiency, and reduce safety risks during the rock cuttings collection process.

[0004] According to this utility model, a device for collecting rock cuttings is provided, comprising: multiple adjusting components, a frame connected to the multiple adjusting components, and a collection box disposed on the upper surface of the frame and having multiple sieve holes.

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

For example, it can be a fixed connection, a detachable connection, or an integral part; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0022] like Figures 1 to 2 As shown, this utility model provides a device 100 for collecting rock cuttings inside a buffer tank. It includes: multiple adjusting components 2, a frame 3 connected to the adjusting components 2, and a collection box 1 disposed on the upper surface of the frame 3. The side wall of the collection box 1 has multiple evenly distributed sieve holes 9 for discharging liquid. A limiting block 4 is fixedly disposed on the side of the collection box 1, and a through hole is provided on the limiting block 4. Each adjusting component 2 includes: an adjusting column 22 and a cylindrical body 21 sleeved on the outer periphery of the adjusting column 22. The inside of the cylindrical body 21 has threads, and the outer periphery of the adjusting column 22 has external threads. The cylindrical body 21 passes through the through hole, and the frame 3 is fixedly connected to the side surface of the cylindrical body 21.

[0023] The following is a brief description of the use of the device 100 for collecting rock cuttings described in this utility model. Since the cylinder 21 is sleeved around the adjusting column 22 and the two are threadedly connected, the cylinder 21 passes through the limiting block 4 located on the side of the collection box 1, and the frame 3 is fixedly connected to the side surface of the cylinder 21, the height of the collection box 1 can be adjusted by turning the adjusting column 22, making the device suitable for buffer tanks of different heights. The adjusting component 2 adjusts the height of the collection drawer 1 from the ground, and the device is placed in the buffer tank (which can be hoisted), ensuring that the discharge pipe of the gas-liquid separator is directly above the collection box 1. The liquid phase and rock cuttings separated by the gas-liquid separator enter the buffer tank and simultaneously enter the collection box 1. The liquid phase flows out from the sieve holes provided on the side wall of the collection box 1, while the rock cuttings are retained inside the collection box 1. When rock cuttings need to be collected, the collection box 1 is removed and collected.

[0024] According to this utility model, since the cylinder 21 is sleeved on the outer periphery of the adjusting column 22 and the two are threadedly connected, the cylinder 21 passes through the limiting block 4 set on the side of the collection box 1, and the frame 3 is fixedly connected to the side surface of the cylinder 21, the height of the collection box 1 can be adjusted by turning the adjusting column 22, which makes it easier for logging personnel to collect rock cuttings, improves the efficiency of rock cuttings collection, and reduces the safety risks in the process of collecting rock cuttings.

[0025] Furthermore, due to the high flow rate of the liquid phase and rock cuttings after treatment by the gas-liquid separator, the rock cuttings rapidly accumulate and cover each other in the buffer tank, making it difficult to remove the rock cuttings at the bottom layer and compromising the accuracy of lithology determination. Using the device 100 described in this invention, the rock cuttings will be deposited in the collection box 1, allowing for rapid removal and analysis, thereby improving the accuracy of lithology determination.

[0026] In one or more embodiments, along the axial direction of the cylinder 21, a first limiting collar 6 and a second limiting collar 8 are respectively fitted on both sides of the limiting block 4. A first elastic element 5 is provided on the outer periphery of the cylinder 21 between the first limiting collar 6 and the limiting block 4, and a second elastic element 7 is provided on the outer periphery of the cylinder 21 between the second limiting collar 8 and the limiting block 4. Optionally, both the first elastic element 5 and the second elastic element 7 can be springs.

[0027] The first elastic element 5 and the second elastic element 7 are used to enhance the vibration of the collection box 1 in the axial direction, thereby enabling rapid drainage and collection of rock cuttings, and improving the rock cuttings collection efficiency. Optionally, the first limiting collar 6 and the second limiting collar 8 are both fixed to the outer periphery of the cylinder 21 by threaded parts.

[0028] In one or more embodiments, the top and bottom ends of the adjusting column 22 extend out of the cylinder 21. The top end of the adjusting column 22 is provided with a torsion member 10, and the bottom end is provided with a pad 13. The torsion member 10 can be used as a leveling reference.

[0029] In one or more embodiments, the collection box 1 is configured as a cuboid with an open top, and each of the four sides of the collection box 1 is provided with a limiting block 4. Optionally, the collection box 1 is provided with handles 11 on opposite sides of the top. Optionally, the collection box 1 is made of stainless steel.

[0030] like Figure 3 As shown, in one or more embodiments, the frame 3 is constructed in a cross shape, and a buffer pad 32 is fitted around the outer periphery of the frame 3. The buffer pad 32 contacts the lower surface of the collection box 1 and is used to apply a buffering effect to the collection box 1.

[0031] In one or more embodiments, the collection box 1 has a guide pipe 12 at the bottom of one side, and a spiral guide plate is provided inside the guide pipe 12. During the collection of rock debris, the guide pipe 12 is closed by a cover. Optionally, the guide pipe 14 is detachably connected to the collection box 1 via a quick-release flange.

[0032] In one or more embodiments, a plurality of sieve holes 9 are arranged in rows and evenly on both sides of the limiting block 4 on the side surface of the collection tank 1. Optionally, the sieve holes 9 are constructed as cylindrical holes inclined at 15° relative to the side surface of the collection tank 1, and the sieve hole diameter 9 is 3 mm, thereby enhancing the permeability of the liquid phase. Optionally, the opening ratio of the sieve holes 9 on the collection tank 1 is 35% to 45%.
