Abstract

The utility model relates to a novel production well wellhead heat insulating device for an oil field, which comprises a front cabinet, a rear cabinet and fasteners. The front cabinet and the rear cabinet are connected to form a heat insulating cabinet body. The heat insulating device is characterized in that a heat insulating cover capable of warping various production well wellheads with different shapes is prefabricated from a composite heat insulating material with a certain thickness to obstruct contact of the wellhead with the air and prevent loss of the heat inside a well due to air interchange with surroundings via the well wall, so as to insulate heat at the wellhead. The cabinet body has a circular arc camber to reduce air resistance, the multi-camber structure enhances the rigidity of the heat insulating cabinet, and the cabinet can be conveniently and rapidly dismounted for wellhead servicing by opening the rapid fasteners on the front cabinet and the rear cabinet. The top of the cabinet body has a plane structure and can be used as a platform for equipment servicing outside the cabinet body. Compared with the prior art, the heat insulating device has the advantages of smart and reasonable concept, good heat insulating effect, effectively improved energy efficiency, good firmness and stability due to the multi-camber cabinet body, multiple functions, and rapid disassembly and assembly.

Description

Novel oil production well head incubator

Technical field:

The utility model relates to a kind of oil well mouth attemperator, is characterized in profiling wrapping up various well head profiles, eliminates cold and hot interchange of air, to reach the heat energy protection, avoids heat-energy losses.Casing forms circular arc camber, reduces windage, and the inspection-pit of devaning is outspoken prompt convenient.The circular arc camber structure has strengthened the rigidity of incubator, and the job platform of plane when can be used as the above overhaul of the equipments of casing gone up on case top.

Background technology:

Present existing oil field shaft mouth incubator presents rectangle parcel well head, forms very big redundant space between well head and the casing, forms the cold-hot air convection exchange, causes heat-energy losses, the forfeiture heat insulation effect, and rectangular box forms big windage, the maintenance well head difficulty of devaning.Because gear housing rigidity is poor, carries out the above operation of casing and must tear open and move incubator or take many shortcomings such as fender bracket.Thereby be badly in need of a kind of novel oil well mouth incubator and replace old-fashioned outmoded incubator.

Summary of the invention:

In order to overcome low and the deficiency that can't quickly dismantled of present existing oil field shaft mouth haybox cooking usefulness; the purpose of this utility model provides a kind of no heat waste; heat protects; play and improve the energy utilization rate effect, the front and back casing of this incubator connects with quick hasp and connects, and dismounting is to satisfy the inspection-pit jaws equipment easily; casing top is anti-skidding plane; can play the effect of working platform when carrying out the operation more than the casing, the profile of circular arc camber obtains little windage, obtains high stability.
