Development Of Insulation Ddevice For Winter Well-control Equipment

The effect of insulation methods has security risks, such as the existence of leakage.In order to comprehensively improve the level of well control equipment, and to find sustainable development of new economic growth points, after a large number of early stage research, feasibility studies, this paper has developed the well control equipment requirements of thermal insulation system to adapt the working environment of Daqing region in winter.Expenditure in accordance with the subject, snubbing pipe sinks feature of well control equipment through winter insulation device design,low-voltage power supply to carry out supporting research and development for construction site of the regulated power supply, use of indoor experimental setup preferred insulation materials; insulation design body structure, design well-controlled temperature control system of thermal insulation devices, well control equipment winter insulation device processing; live and experimental, such as installation and debugging of the implementation of the link. A set of well control equipment insulation in winter heating device is designed, the heating body is used to heat well-controlled heating insulation.The use of nickel-chromium hot metal filament method to spot welding nickel-chromium wire heating in an enclosed body, on both sides with mica-chip package in order to achieve the purpose of insulation. Body is heated in accordance with the different geometry of the system corresponding to the shape of the insulation of heating modules, when used only in accordance with the different heating body geometry module to insulation group on the installation of heating, Nagarze Fast installation, fast and convenient. Excellent performance through the selection of insulation compound silicate insulation material as a thermal insulation material of the subject, not only to resolve the issue of the installation location of space constraints, but also to ensure that the insulation of the economy. Distribution system for the use of dry-type isolation transformer power supply, 380V variable safe working voltage of 36V, voltage stability value between 36V±1V, distribution box using pluggable structure, outside with a metal shield. Body heating power leads to the use of epoxy resin package, the whole system has good performance of explosion-proof. Heater features automatic temperature control to ensure that the object is heated the temperature does not exceed the allowable safe temperature. Dismantling the entire system fast, convenient, reusable, and ensure the team well more economical to use.In order to verify whether the device meets the design and project requirements, tests of indoor and outdoor are both done. Test results show that the well control equipment developed by the winter heating device insulation can meet the design requirements, and can also meet the needs of the sets of heat insulation device which is not only effective but also safe, convenient, easy to operate.
