Description

Technical Field

[0001] The invention relates to a heat-insulating sand-washing bucket and a temperature control method thereof, belonging to the technical field of logging operations. Background Art

[0002] In the oil and gas industry, sand washing is the first key procedure for logging operations to obtain first-hand geological data. After the sand sample passes through the vibrating screen from the bottom of the well to the ground, it needs to be cleaned to remove the drilling fluid and improve the visibility of the sand sample. However, in some low-temperature environments, the heat of the water body is easily lost during the sand washing process, and even ice may form, making the sand washing operation difficult and the sand washing effect poor, affecting the identification of rock properties. In addition, traditional sand washing buckets often have deficiencies in thermal insulation, and are placed in outdoor environments, which cannot meet the needs of low-temperature environment operations. Therefore, it is necessary to design a sand washing bucket that can effectively heat up and keep warm, so as to improve the quality of operations and reduce the damage caused by long-term contact of personnel's hands with low-temperature environments. Summary of the invention

[0003] The invention designs and develops a heat-insulating sand washing bucket, which can heat the inner bucket during the sand washing operation and keep the heat through the outer bucket, thereby improving the operation quality and reducing the damage caused by long-term contact of personnel's hands with the low temperature environment.
