Description
Technical field
The utility model relates to the drill pipe sub of oil-drilling field, specifically a kind of drill pipe sub with automatic generating structure.
Background technology
Current oil-drilling field, adopts drilling rod to connect drill bit, to transmit moment of torsion in drilling process, thus drills. Every root drilling rod used, one male one female two drill pipe subs are welded at two ends respectively. Male joint is screwed mutually by screw thread with conical internal thread, hermaphrodite connector with conical external screw thread, female joint. Screwed interconnection between each drilling rod by hermaphrodite connector. Usually having tens to several hundred drilling rods interconnection in a usual well, its total length can reach several hundred meters to thousands of rice. Have the electrical equipments such as various sensor signal receptor and signal amplifier in well, for each item data such as the temperature under production wells, pressure and carry out being sent to ground. The traditional way of its transfer is after drilling rod connects, and adopts wire cable to transmit. Driving electric power needed for the work of each electrical equipment is normally provided by high temperature resistant battery. Usually, the life-span of battery is only 5-10 and namely lost efficacy. Meanwhile, being subject to the current consumption impact of electrical equipment, usually before battery failure, the electricity of battery is depleted. Thus after a period of operation, electrical equipment no longer works because not having driven by power, and ground does not receive signal, at this time if it is intended to continue to accept the signal of underground, it is necessary to equipment takes out replacing battery again and safeguards. Owing to the degree of depth of drilling well reaches hundreds of rice and even upper km usually, change the cost of battery and cost will be very high, the manpower of at substantial, financial resources and material resources. Simultaneously owing to needing part equipment to stop work when changing battery, by having influence on normally carrying out or the normal exploitation of crude oil of work, cause unnecessary waste. It is badly in need of this kind of power supply mode being improved.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thus provides a kind of drill pipe sub with automatic generating structure. The utility model is solved the problems of the technologies described above by following technical proposals: a kind of drill pipe sub with automatic generating structure, comprising: male joint 1, first magnet 2, the 2nd magnet 3, first generating pole 4, the 2nd generating pole 5, wire 6, voltage stabilizing circuit 7 and output interface 8; The inside of described male joint 1 is hollow structure, and described male joint 1 comprises: inwall 11, outside screw 12 and end face 13; Described inwall 11 is along the circumferential direction respectively arranged with the first magnet 2, first generating pole 4, the 2nd magnet 3, the 2nd generating pole 5 in order every 90 degree, and the magnetic pole of described first magnet 2 and the 2nd magnet 3 is arranged on the contrary; The input terminus that described first generating pole 4 and the 2nd generating pole 5 are connected on voltage stabilizing circuit 7 by wire 6, the output terminal of described voltage stabilizing circuit 7 is connected with and exports interface 8; Having a groove on described end face 13, described voltage stabilizing circuit 7 is arranged in groove.
Preferential, described inwall 11 along the circumferential direction has a groove every 90 degree, described first magnet 2, first generating pole 4, the 2nd magnet 3, the 2nd generating pole 5 are separately positioned in four grooves in order.
A kind of drill pipe sub with automatic generating structure of the utility model, principle of work according to generator, under magnetic induction line effect between magnet, when drilling liquid flow is out-of-date, owing to drilling fluid has certain electroconductibility, during drilling fluid cutting magnetic induction line, two generating poles will accumulate positive charge and negative charge respectively.
