Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration hole treatment, in particular to a tool for treating geological exploration holes in a reservoir. Background Art

[0002] A geological exploration hole in a reservoir is a hole drilled during geological exploration in the early stage of reservoir construction. After the exploration work is completed, the exploration hole is sealed to prevent groundwater pollution and ground subsidence. Since the reservoir geology mainly includes cohesive soil, silty loam, and silty clay, etc., in the initial exploration stage, geological exploration holes are drilled at different positions in a large area to provide important reference parameters for the later design stage. During the process of plugging the geological exploration holes, the geological holes are relatively small, directly 30 - 50 cm in diameter, and are distributed in many points in the reservoir, making it inconvenient to construct for plugging these holes.

[0003] The plugging methods include grouting plugging, concrete plugging, plugging with plugs, and plugging with synthetic materials. Currently, grouting plugging and concrete plugging are often used for plugging geological exploration holes in reservoirs. The water in the geological exploration hole is drained by a water pump, and then the plugging slurry or concrete is directly injected into the geological exploration hole by a grouting pump. The equipment used in the construction is implemented separately, and the construction is cumbersome and cannot effectively improve the plugging efficiency. Summary of the Utility Model

[0004] The purpose of the utility model is to solve the deficiencies existing in the prior art and propose a tool for treating geological exploration holes in a reservoir.

[0005] To achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A tool for treating geological exploration holes in a reservoir, comprising a hopper, a support base, lifting rods, an outer drainage cylinder, and an inner feeding pipe. The outer side of the hopper is connected to the support base through a plurality of lifting rods. The bottom of the hopper is communicated with the inner feeding pipe. A downward one-way gravity valve plate B is arranged at the bottom of the inner feeding pipe. The inner feeding pipe is sleeved with an outer drainage cylinder. A drain pipe is arranged on the side wall at the upper end of the outer drainage cylinder. The top of the outer drainage cylinder is fixed to the bottom of the hopper. The bottom of the outer drainage cylinder is connected to the inner feeding pipe through a fixed ring plate. The fixed ring plate is evenly provided with water inlets and drain holes. An upward one-way gravity valve plate A is arranged at the water inlet of the fixed ring plate facing the inside of the outer drainage cylinder. A plugging ring plate is correspondingly arranged at the bottom of the fixed ring plate. The plugging ring plate is provided with the same water inlets corresponding to the water inlets of the fixed ring plate, and the plugging ring plate is provided with plugging blocks corresponding to the drain holes of the fixed ring plate.

[0007] One end of the lifting rod is rotatably connected to the outer wall of the hopper, and the other end of the lifting rod is rotatably connected to the support base.

[0008] There is an opening between the fixed ring plate and the plugging ring plate, and the middle between the fixed ring plate and the plugging ring plate corresponds to the one-way gravity valve plate B.

[0009] There are more than 3 lifting rods, and they are synchronous lifting rods.

[0010] The fixed ring plate and the plugging ring plate are magnetically fixed. The fixed ring plate is an iron plate, and the plugging ring plate is a magnetic plate; the plug on the plugging ring plate is a rubber plug.

[0011] The beneficial effects of the present utility model are as follows: the structure is simple, and it is very convenient for construction operations and carrying. When dealing with the geological exploration holes of the reservoir, drainage and plugging are carried out continuously, avoiding plugging after pumping water with a water pump, improving the plugging efficiency, and greatly improving the plugging efficiency.

Detailed Implementation Modes

[0018] Embodiment 1

[0019] As Figures 1-5As shown in the figure, the utility model provides a processing tool for reservoir geological exploration holes, and its structure is as follows: it includes a hopper 1, a support base 2, a lifting rod 3, an outer drainage cylinder 4 and an inner feeding pipe 5. The outside of the hopper 1 is connected to the support base 2 through multiple lifting rods 3. One end of the lifting rod 3 is rotatably connected to the outer wall of the hopper 1, and the other end of the lifting rod 3 is rotatably connected to the support base 2. The bottom of the hopper 1 is communicated with the inner feeding pipe 5. A downward one-way gravity valve plate B is arranged at the bottom of the inner feeding pipe 5. An outer drainage cylinder 4 is sleeved outside the inner feeding pipe 5. There is a gap of 4-8 cm between the inner feeding pipe 5 and the outer drainage cylinder 4. A drain pipe 41 is arranged on the side wall at the upper end of the outer drainage cylinder 4. The top of the outer drainage cylinder 4 is fixed to the bottom of the hopper 1. The bottom of the outer drainage cylinder 4 is connected to the inner feeding pipe 5 through a fixed ring plate 42. Water inlet holes 44 and drain holes 45 are evenly arranged on the fixed ring plate 42. An upward one-way gravity valve plate A is arranged at the water inlet hole 44 of the fixed ring plate 42 facing the inside of the outer drainage cylinder 4. A sealing ring plate 43 is correspondingly arranged at the bottom of the fixed ring plate 42. The same water inlet holes 44 corresponding to the water inlet holes 44 of the fixed ring plate 42 are arranged on the sealing ring plate 43. Plugging blocks 46 corresponding to the drain holes 45 of the fixed ring plate 42 are arranged on the sealing ring plate 43; there is an opening between the fixed ring plate 42 and the sealing ring plate 43, and the middle between the fixed ring plate 42 and the sealing ring plate 43 corresponds to the one-way gravity valve plate B; 3 lifting rods 3 are evenly arranged at equal intervals and are synchronous lifting rods 3; the fixed ring plate 42 and the sealing ring plate 43 are magnetically fixed. The fixed ring plate 42 is an iron plate, and the sealing ring plate 43 is a magnetic plate; the plugging blocks 46 on the sealing ring plate 43 are rubber plugs;

[0020] Specifically, when in use, the support base 2 is fixed around the exploration hole, so that the outer drainage cylinder 4 and the inner feeding pipe 5 are aligned with the exploration hole. The lifting rods 3 are controlled to descend synchronously, so that the outer drainage cylinder 4 and the inner feeding pipe 5 extend into the exploration hole. While descending, the water in the exploration hole makes the one-way gravity valve A47 on the fixed ring plate 42 open by extrusion. The water in the exploration hole flows into the gap between the outer drainage cylinder 4 and the inner feeding pipe 5. When the water level between the outer drainage cylinder 4 and the inner feeding pipe 5 reaches the position of the drain pipe 41, it is directly discharged through the drain pipe 41; when the bottom of the outer drainage cylinder 4 reaches the bottom of the exploration hole, the lifting of the lifting rod 3 is stopped. Plugging slurry or concrete is added into the hopper 1, and the slurry or concrete in the hopper 1 flows into the inner feeding pipe; then the lifting rods 3 are controlled to rise, so that the outer drainage cylinder 4 and the inner feeding pipe 5 are pulled out of the exploration hole upward. At the same time, the slurry or concrete in the inner feeding pipe 5 extrudes the one-way gravity valve B51 to open and flows into the exploration hole. When the outer drainage cylinder 4 and the inner feeding pipe 5 are completely pulled out of the exploration hole, the plugging is completed;

[0021] The reservoir geological exploration hole processing tool can be used continuously without discharging the water between the outer drainage cylinder and the inner feeding pipe once. After using the reservoir geological exploration hole processing tool, the sealing ring plate can be removed, and the water between the outer drainage cylinder and the inner feeding pipe can be discharged through the drainage holes. If the area between the drainage cylinder and the inner feeding pipe needs to be cleaned, water can be connected through the pipe orifice of the drainage pipe to flush the area between the drainage cylinder and the inner feeding pipe. After cleaning, the sealing ring plate can be reinstalled in place.
