[0025] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0026] To improve the hardness of the thermal recovery casing head, such as Figures 1-4 As shown, the present invention provides a high-hardness thermal recovery sleeve head that is easy to assemble, comprising a thermal recovery sleeve head 1, a first flange 2 connected to the top of the periphery of the thermal recovery sleeve head 1, a second flange 3 connected to the lower end of the periphery of the thermal recovery sleeve head 1, a bypass pipe 4 installed on one side of the thermal recovery sleeve head 1, and a bypass valve 5 provided on one side of the bypass pipe 4.
[0027] A grease injection channel 12 is installed on the other side of the thermal recovery casing head 1. A grease injection port 13 is connected to the top of the grease injection channel 12. An oil and gas outlet 8 is connected to the top of the thermal recovery casing head 1. Ceramic plates 15 are provided on the inner sides of both the thermal recovery casing head 1 and the oil and gas outlet 8. Reinforcing ribs 10 are evenly arranged around the inner wall of the thermal recovery casing head 1.
[0028] When in use, the reinforcing rib 10 can effectively improve the overall structural hardness and strength of the thermal recovery casing head 1;
[0029] The ceramic plate 15 can reduce the impact and wear of oil and gas flow on the inner wall of the thermal recovery casing head 1 and the oil and gas outlet 8, thereby improving the hardness and durability of the casing head.
[0030] For example, such as Figure 1 , Figure 2 , Figure 3 As shown, a base 7 is provided at the bottom of the thermal extraction sleeve head 1, and a fixing plate 6 is evenly provided between the base 7 and the second flange 3. The top and bottom of the fixing plate 6 are respectively connected to the bottom of the second flange 3 and the top of the base 7.
[0031] When in use, the fixing plate 6 can effectively enhance the stability of the connection between the second flange 3 and the base 7, thereby enhancing the stability of the connection.
[0032] For example, such as Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, the outer surface of the ceramic plate 15 is coated with an anticorrosive coating 11, which is made of epoxy zinc-rich anticorrosive paint.
[0033] In use, the anticorrosive coating 11 can significantly improve the hardness and wear resistance of the ceramic plate 15.
[0034] As shown, Figure 1 , Figure 2 , Figure 3 As shown, mounting holes 9 are provided around the first flange plate 2 and the second flange plate 3.
[0035] In use, the mounting holes 9 facilitate personnel to detachably connect the externally connected pipeline to the thermal recovery casing head 1 through the first flange plate 2 and the second flange plate 3.
[0036] As shown, Figure 3 As shown, the bottom of the thermal recovery casing head 1 is provided with a sleeve interface 14.

[0039] In use, the pressure sensor 16 can detect the pressure parameters around and in the well in real time, ensuring the safe and effective performance of the thermal recovery operation.
[0040] When the new thermal recovery casing head 1 is used, the personnel evenly set the reinforcing ribs 10 inside the thermal recovery casing head 1, which can effectively improve the overall structural hardness and strength of the thermal recovery casing head 1.
[0041] By setting the ceramic plate 15 inside the thermal recovery casing head 1 and the oil and gas outlet 8, the impact and wear of the oil and gas flow on the inner walls of the thermal recovery casing head 1 and the oil and gas outlet 8 can be reduced, thereby improving the hardness and durability of the casing head;
[0042] The personnel connect the oil and gas outlet 8 with the top of the thermal recovery casing head 1, the inner diameter of the oil and gas outlet 8 is larger than that of the thermal recovery casing head 1, when the oil and gas with smaller inner diameter flows into the oil and gas outlet 8 with larger inner diameter, the speed and momentum of the oil and gas will decrease, thereby reducing the impact force of the oil and gas on the inner walls of the thermal recovery casing head 1 and the oil and gas outlet 8, which helps the thermal recovery casing head 1 and the oil and gas outlet 8 to maintain a high hardness for a long time;
[0043] Through the grease injection channel 12 and the grease injection port 13, personnel can inject high-pressure sealing grease into the connecting part of the thermal recovery casing head 1, which can ensure the sealing performance of the thermal recovery casing head 1.
