Description

Technical Field

[0001] The utility model relates to the technical field of oil field detection equipment, in particular to an eccentric embedded antifreeze gate device. Background Art

[0002] Oil and water well pressure gauge gates are typically installed via threaded connections on a short nipple welded vertically to the wellhead pipeline. The pressure gauge is also threaded onto the gate via the nipple. Because the pressure gauge is distant from the wellhead pipeline and the fluid transmitting pressure is stagnant, gate freezing often occurs during winter temperatures. This is a common but challenging problem. Freezing-proofing oil and water well pressure gauge gates is an important maintenance task, crucial to oilfield production operations.

[0003] To prevent freezing of pressure gauge gates in oil and water wells, insulation is typically applied. This involves covering the gate surface and related structures with insulation materials, such as foam plastics and fiberglass, to reduce heat loss. Alternatively, electric heating can be used to raise the temperature around the pressure gauge gate to prevent freezing. However, even with insulation measures, freezing can occur during extremely cold winters, especially when the pressure gauge is located long distances from the wellhead pipeline. Using electric heating not only increases costs but is also impractical in wells due to the lack of grid power.

This series of sensors are communicatively connected to the instrument head above. It can simultaneously realize the accurate measurement of the crude oil water content, temperature, and pressure of a single well and remote transmission of data.
