Abstract
An electric heating wellhead heat preservation box belongs to the technical field of petroleum exploitation matching devices. The heat preservation box is connected with heat preservation box sample window, and the fixed bolster is connected to the heat preservation box, and the fixed bolster connects the electric heat line, and 2 fixed bolsters are installed respectively and are connected the electric heat line and constitute a set of heating device between the both sides of heat preservation box, 2 fixed bolsters, and multiunit heating device arranges and installs on the heat preservation box, the electric heat line series connection between every group. The utility model has the advantages that can guarantee the heat preservation requirement of oil-water well head in winter, can realize again that well head heat preservation equipment's quick safety is pulled apart, guaranteed the safety of well head maintenance construction operation. Test well LU7142 well Using this technique, the flat-to-temperature in the insulation box was 20 ℃ during the coldest 12 months of the winter. The LU7220 well which is combined with the original heat preservation box and an electric heating cup for heat preservation has little difference of 21 ℃ of the average temperature inside the heat preservation box in the same period, and can meet the temperature required by the heat preservation of a wellhead in winter.
Description
Technical field
The utility model relates to a kind of electrical heating well head incubation chamber, belongs to oil exploitation corollary apparatus technical field.
Background technology
Xinjiang Oilfield oil-water well well head Winter protection all adopts the Insulation of well head incubation chamber and electric cup combination.Electric cup in incubation chamber has larger drawback after long-term dismounting is used: once the situations such as production tree generation oil gas evaporating, emitting, dripping or leaking of liquid or gas in seal cavity, the use of " old " electric cup will become a large potential safety hazard; During oil-water well well workover, construction party will be separated electric cup power-off, easily damages electric cup in frequent operation process, runs into electric cup aging circuit, forgets the power-off accident such as probably get an electric shock, catch fire.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of electrical heating well head incubation chamber.
At silicate board inwall of incubation chamber, install one group of heating wire that thermal source is provided additional, heating wire power supply can disconnect fast.Together with the heat preserving mode of the incubation chamber of sealing and heating wire heat supply combination, keep the required temperature of winter oil well well head.When wellhead maintenance operation, incubation chamber can be separated to well head together with heating wire simultaneously, realize and carry out quickly and easily wellhead maintenance operation, improve constructor's safety in well workover.
A kind of electrical heating well head incubation chamber, incubation chamber is connected with incubation chamber sampling window, incubation chamber is connected and fixed support, fixed support connects heating wire, 2 fixed supports are arranged on respectively and between the both sides of incubation chamber, 2 fixed supports, connect heating wire and form one group of heater, many group heaters are arranged and are arranged in incubation chamber, and the heating wire between every group is connected in series.
The utility model has the advantages that the insulation requirement that can guarantee winter oil well well head, can realize fast and safely separating of well head heat-preserving equipment again, guaranteed the safety of wellhead maintenance construction operation.When test well LU7142 well is used this technology, in the winter time the coldest December, putting down in incubation chamber is 20 ℃ to temperature.Add the LU7220 well of electric cup composite thermal insulation with original incubation chamber, 21 ℃ of the inner average temperature of same time incubation chamber are more or less the same, and can meet winter well head and be incubated desired temperature.
Accompanying drawing explanation
When considered in conjunction with the accompanying drawings, by the detailed description with reference to below, can more completely understand better the utility model and easily learn wherein many advantages of following, but accompanying drawing described herein is used to provide further understanding of the present utility model, form a part of the present utility model, schematic description and description of the present utility model is used for explaining the utility model, do not form improper restriction of the present utility model, as schemed wherein:
Fig. 1 is structural representation of the present utility model.
Below in conjunction with drawings and Examples, the utility model is further illustrated.
The specific embodiment
Obviously, the many modifications and variations that those skilled in the art do based on aim of the present utility model belong to protection domain of the present utility model.
Embodiment 1: as shown in Figure 1, a kind of electrical heating well head incubation chamber, incubation chamber 3 is connected with incubation chamber sampling window 4, incubation chamber 3 is connected and fixed support 2, fixed support 2 connects heating wire 1,2 fixed supports 2 are arranged on respectively between the both sides of incubation chamber 3,2 fixed supports 2 and connect one group of heater of heating wire 1 composition, organize heater arrangement more and are arranged in incubation chamber 3, and the heating wire 1 between every group is connected in series.
The utility model is fixed on approximately 10 meters of heating wires of a group leader on incubation chamber inwall with 20 fixed supports on existing incubation chamber inwall, at incubation chamber side face drilling one aperture, it can be connected by being fixed on the junction box realization of incubation chamber outer wall with power line.Electrical heating well head incubation chamber replaces the heat preserving mode of original incubation chamber and electric cup combination with the incubation chamber of sealing and the oil-water well well head heat preserving mode of heating wire heat supply combination.Meanwhile, well head only need disconnect line can remove well head incubation chamber and well head heating and thermal insulation system, facilitates the operation of oil recovery routine work.
As mentioned above, embodiment of the present utility model is explained, but as long as not departing from fact inventive point of the present utility model and effect can have a lot of distortion, this will be readily apparent to persons skilled in the art.Therefore, within such variation is also all included in protection domain of the present utility model.
