How to choose a thermos flask suitable for petroleum logging?

Temperature retention ability: For petroleum logging, the thermos housing needs to be able to effectively maintain a stable internal temperature for a certain period of time. This is extremely important for protecting downhole instruments and samples. Choosing an thermos housing with good insulation performance can ensure that the temperature change during the logging process is as small as possible.
Pressure resistance ability: During the process of petroleum logging, the thermos housing may be subjected to pressure from downhole. Therefore, it is very important to choose thermos housing with sufficient pressure resistance. This can ensure that the thermos housing will not be damaged by pressure during the logging process, thus protecting the internal instruments and samples.

Insulation material: The insulation material of an thermos housing is one of the key factors affecting its insulation performance. Common insulation materials include polyurethane foam, vacuum insulation panels, etc. Polyurethane foam has good insulation performance and cost-effectiveness, while vacuum insulation panels have higher insulation efficiency but a relatively higher price. When choosing a thermos housing, you can learn about the types and properties of its insulation materials and select a product that suits your needs. At the same time, you can also consider factors such as the durability and environmental friendliness of the insulation materials.

Sealing performance: Good sealing performance is the key to ensuring the pressure resistance of a thermos housing. If the sealing of the thermos housing is not good, leakage may occur when it is under pressure, thus affecting its use effect. Choosing a thermos housing with reliable sealing performance can ensure the stability of the internal pressure during the logging process and protect the safety of instruments and samples.

Size and capacity: The size and capacity of the thermos housing should be selected according to the size and needs of the logging equipment. If the thermos housing  is too large, it may be inconvenient to carry and operate; if it is too small, it may not be able to meet the needs during the logging process. When choosing an thermos housing, you can consider the size and shape of the logging equipment, as well as the quantity and volume of the instruments and samples that need to be insulated. Choosing an insulated bucket with an appropriate size and moderate capacity can improve work efficiency and facilitate logging operations.

Material and quality: The environment for petroleum logging is usually harsh. The thermos housing needs to have sufficient durability and be able to withstand the tests of various harsh conditions. Choosing thermos housing made of strong and durable materials can ensure that it will not be easily damaged during the logging process.
