Description
Technical field
The utility model relates to a kind of marine drilling Wax proofing equipment, particularly the efficient decreasing and wax-coagulation-preventing device of a kind of marine drilling.
Background technology
In marine drilling manufacturing process, when oil stream is from shaft bottom to moving uphole, well temperature declines gradually, when lower than wax precipitation point, wax contained in crude oil will be separated out, blocking oil flow channel, affect oil well production, needing to carry out wax removal to oil well just can make oil well normally produce, existing dewaxing method is more, and one is that hot water circuit well-flushing makes wax dissolve to flow out, but the low well of strata pressure is not suitable for hot water circuit well-flushing, because the well that strata pressure is low can not form circulation, hot water can enter stratum and cause oil layer pollution; Another kind is in oil well, add wax removal Ji, and this method cost is high, and overhead cost are high, less economical.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, provides a kind of marine drilling efficient decreasing and wax-coagulation-preventing device, and structure is simple, easy for installation, safe and reliable.
Its technical scheme is: comprise central tube, pressure cap, Electromagnetical anti-wax machine, spring, check pin and Wheel drilling joint, the middle part of central tube is provided with groove, by check pin Motionless electromagnetic wax control device on described groove, the two ends of described Electromagnetical anti-wax machine are fixed on central tube by pressure cap, spring supporting is passed through between Electromagnetical anti-wax machine and central tube, the end of central tube connects Wheel drilling joint, described Electromagnetical anti-wax machine comprises Main Control Tank, water back, electromagnetic coil, humidity sensor, humidity sensor is fixed on the two ends of central tube, electromagnetic coil is distributed on the inwall of water back in the shape of a spiral, described humidity sensor is connected Main Control Tank with electromagnetic coil, Main Control Tank is by receiving the reflex control electromagnetic coil work of humidity sensor, the two ends of described water back seal respectively by packing layer.
The outside of above-mentioned water back is provided with isolation layer, realizes effective Wax proofing.
The beneficial effects of the utility model are: wax control result is obvious; Automatically duty is entered, substantially without the need to monitoring maintenance after energising; Structure is simple, easy for installation, safe and reliable; Energy-conservation---power consumption is low, and power consumption is low, and the 24h power consumption that operates continuously is no more than 7.5kwh; Down-hole lifting tubing string and ground oil transportation flow process pipeline can be acted on simultaneously; Effective prolongation time between well-flushings, obviously reduce the running cost of mud oil.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
Accompanying drawing 2 is structural representations of the present utility model;
In upper figure: central tube 1, pressure cap 2, Electromagnetical anti-wax machine 3, spring 4, check pin 5 and Wheel drilling joint 6; Main Control Tank 3.1, water back 3.2, electromagnetic coil 3.3, humidity sensor 3.4.
Detailed description of the invention
1-2 by reference to the accompanying drawings, the utility model will be further described:
The utility model comprises central tube 1, pressure cap 2, Electromagnetical anti-wax machine 3, spring 4, check pin 5 and Wheel drilling joint 6, the middle part of central tube 1 is provided with groove, by check pin 5 Motionless electromagnetic wax control device 3 on described groove, the two ends of described Electromagnetical anti-wax machine 3 are fixed on central tube 1 by pressure cap 2, supported by spring 4 between Electromagnetical anti-wax machine 3 and central tube 1, the end of central tube 1 connects Wheel drilling joint 6, described Electromagnetical anti-wax machine 3 comprises Main Control Tank 3.1, water back 3.2, electromagnetic coil 3.3, humidity sensor 3.4, humidity sensor 3.4 is fixed on the two ends of central tube 1, electromagnetic coil 3.3 is distributed on the inwall of water back 3.2 in the shape of a spiral, described humidity sensor 3.3 is connected Main Control Tank 3.1 with electromagnetic coil 3.3, Main Control Tank 3.1 is worked by the reflex control electromagnetic coil 3.3 receiving humidity sensor 3.4, the two ends of described water back 3.2 seal respectively by packing layer.
The outside of described water back 3.2 is provided with isolation layer, realizes effective Wax proofing.
Operating principle:
When pipeline has liquid by central tube, in Electromagnetical anti-wax machine 3, the humidity sensor 3.4 of water back inside receives induced signal, Main Control Tank 3.1 is worked by the reflex control electromagnetic coil 3.3 receiving humidity sensor 3.4, electromagnetic coil 3.3 forms electromagnetic field and realizes the intensification of water back inwall, thus to make in pipeline liquid heat up and under magnetic fields molecular assembly, reduce liquid viscosity, liquid is by after the heating of this water back, temperature increase, molecular assembly, viscosity reduce, and can effectively suppress profit fouling.
The above is only preferred embodiment of the present utility model, and any those of ordinary skill in the art all may utilize the technical scheme of above-mentioned elaboration to the utility model correct or are revised as equivalent technical scheme.Therefore, any simple modification of carrying out according to the technical solution of the utility model or substitute equivalents, belong to the greatest extent the scope that the utility model is claimed.
