Description

Technical Field

[0001] The utility model relates to the technical field of drilling, in particular to a liquid thermal insulation structure for drilling. Background Art

[0002] Drilling or exploration is the use of deep drilling mechanical engineering technology to exploit underground or seabed natural resources, or to take actual profiles of strata and extract physical samples for experiments to obtain relevant data. In order to ensure the normal operation of the drilling rig, the water pipes must be kept warm to ensure that the drilling fluid in the water pipes is not frozen.

[0003] For example, a drilling water pipe insulation device with the announcement number "CN220470961U" is used. When in use, the heating belt is powered by a generator, and the heating belt heats the water pipe to ensure the temperature of the water pipe. The applicant has proved in practice that water can be supplied normally at minus thirty degrees, so that drilling work can be carried out normally. The heating belt and the water pipe are wrapped with insulation cotton. The insulation cotton plays the role of fixing the heating belt on the water pipe, which is convenient for operation. At the same time, it also plays a role of insulation, further enhancing the insulation effect. However, in the drilling water pipe insulation device, the heating belt fits the outer wall of the water pipe, and the contact area is limited. It takes a long time to heat the water pipe, which reduces work efficiency. At the same time, the insulation cotton needs to be wrapped around the heating belt and the outside of the water pipe, which is easy to cause some areas to be loosely wrapped and leak, causing the temperature of the water pipe to drop faster, reducing the work quality. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that the heating belt fits closely with the outer wall of the water pipe, the contact area is limited, and it takes a long time to heat the water pipe, thereby reducing work efficiency. At the same time, the insulation cotton needs to be wrapped around the heating belt and the outside of the water pipe, which may easily lead to air leakage in some areas due to loose winding, causing the temperature of the water pipe to drop faster and reducing work quality. A liquid insulation structure for drilling is proposed.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A drilling liquid insulation structure is designed, comprising a water pipe, wherein the outer wall of the water pipe is provided with a heating mechanism;

[0007] The heating mechanism comprises a heating belt and a groove. The outer wall of the water pipe is processed with a plurality of grooves. The inner wall of the groove is in contact with the heating belt. The outer wall of the heating belt is wrapped with thermal insulation cotton.

[0008] Preferably, the outer wall of the thermal insulation cotton is provided with a thermal insulation mechanism, and the thermal insulation mechanism includes a first semi-cylinder and bolts, multiple first fixing plates are processed on both sides of the first semi-cylinder, the inner side of the first semi-cylinder is fitted with the second semi-cylinder, and multiple second fixing plates are processed on both sides of the second semi-cylinder.

[0009] Preferably, the inner side of the second fixing plate is in contact with the first fixing plate.

[0010] Preferably, the bolts pass through the first fixing plate and the second fixing plate respectively through through holes.

[0011] Preferably, the bolt is threadedly connected to the nut.

[0012] The utility model provides a liquid insulation structure for drilling, which has the beneficial effect that: through the cooperation of the water pipe and the heating mechanism, the heating belt is installed in the groove processed on the water pipe filled with the drilling liquid, the heating belt is tightly pressed against the inner wall of the groove on the water pipe, so that the side and bottom of the heating belt are in contact with the water pipe, the contact area between the heating belt and the water pipe is increased, and the drilling liquid in the water pipe can be heated in a shorter time, thereby improving the working efficiency.

[0013] Through the cooperation of the thermal insulation cotton and the thermal insulation mechanism, the thermal insulation cotton is wrapped around the outside of the heating belt and the water pipe, and then the first semi-cylinder and the second semi-cylinder are selected to make the thermal insulation cotton close to the outside of the heating belt and the water pipe, and then the first semi-cylinder and the second semi-cylinder are buckled on the outer wall of the thermal insulation cotton, and the bolts are passed through multiple first fixing plates and second fixing plates respectively. Then the operator turns a nut to fix the first fixing plate and the second fixing plate. The first semi-cylinder and the second semi-cylinder can make the thermal insulation cotton close to the outside of the heating belt and the water pipe, which can avoid air leakage as much as possible and make the temperature of the drilling liquid in the water pipe drop more slowly, thereby improving the work quality.

DETAILED DESCRIPTION

The outer wall of the water pipe 1 is processed with multiple grooves 202, and the grooves 202 are in a spiral state. The inner walls of the grooves 202 are in contact with the heating belt 201. The heating belt 201 is flat and has an elliptical cross-section, similar to an electric wire. The outer wall of the heating belt 201 is wrapped with insulation cotton 3.

[0022] An insulation mechanism 4 is provided on the outer wall of the insulation cotton 3, and the insulation mechanism 4 includes a first semi-cylinder 401 and a bolt 405. Multiple first fixing plates 403 are processed on both sides of the first semi-cylinder 401, and the inner side of the first semi-cylinder 401 is fitted with the second semi-cylinder 402. Multiple second fixing plates 404 are processed on both sides of the second semi-cylinder 402, and the inner sides of the second fixing plates 404 are fitted with the first fixing plates 403. The bolts 405 pass through the first fixing plates 403 and the second fixing plates 404 respectively through through holes, and the bolts 405 are threadedly connected with the nuts 406.

[0023] Working principle:

[0024] When using insulation structures to insulate drilling fluids:

[0025] Preparation process:

[0026] First, the heating belt 201 is wound around the spiral groove 202 processed on the water pipe 1 containing drilling liquid. The spiral groove 202 facilitates the installation of the heating belt 201. During installation, the operator does not need to hold the heating belt with one hand all the time. At the same time, the contact area between the heating belt 201 and the water pipe 1 can be increased. It only takes a shorter time to heat the drilling liquid in the water pipe 11, thereby improving work efficiency.

[0027] Insulation cotton fixing process:

[0028] Wrap the thermal insulation cotton 3 around the outside of the heating belt 201 and the water pipe 1, and then select the first semi-cylinder 401 and the second semi-cylinder 402 that can make the thermal insulation cotton 3 close to the outside of the heating belt 201 and the water pipe, and then buckle the first semi-cylinder 401 and the second semi-cylinder 402 on the outer wall of the thermal insulation cotton 3, pass the bolts 405 through multiple first fixing plates 403 and second fixing plates 404 respectively, and then the operator rotates the nuts 406 to fix the first fixing plates 403 and the second fixing plates 404. The thermal insulation cotton 3 can be closely attached to the outside of the heating belt 201 and the water pipe 1 through the first semi-cylinder 401 and the second semi-cylinder 402. At the same time, a sealing gasket is provided between the first semi-cylinder 401 and the second semi-cylinder 402 to avoid air leakage as much as possible, so that the temperature of the drilling liquid in the water pipe 1 drops more slowly, thereby improving the work quality.
