Abstract
The utility model discloses a hard electrode capable of being maintained which is mainly composed of an upper connector, a body, a connector and a lower connector, wherein the lower connector is fixedly connected with the connector. A locking shaft is fixedly connected to the upper connector and is placed on the inner side of the body and the connector. An insulation sleeve is sleeved on the locking shaft and is placed on the inner side of the body and the connector. An insulation gasket is sleeved on the outer side of the insulation sleeve and is placed between the body and the connector. An insulation ring is sleeved outside the body, the insulation gasket and the connector, and is placed between the body and the connector. An outer shell capable of preventing hydrogen sulfide gas is sleeved outside the hard electrode capable of being maintained, the locking shaft is fixedly connected to the upper connector through a thread, and the locking shaft and the upper connector can be detached and separated. The lower connector is fixedly connected with the connector through a thread, and the lower connector and the connector can be detached and separated. The hard electrode capable of being maintained has the advantages of being simple in structure, convenient to use, long in service life, high in working efficiency and capable of being detached and maintained.
Description
Technical field
The present invention relates to a kind of hard electrode, but the hard electrode of especially mainly being formed by top connection, main body, connector and the lower contact of fixedlying connected with connector of maintenance type.
Background technology
Hard electrode when going into the well be bilateral to the slider of electrode system instrument loop electrode, be again the carrier of natural potential apparatus measures ring simultaneously.Hard electrode body has insulating properties, and it can keep spacing and insulation between emission electrode and the loop electrode, for emission electrode and loop electrode provide distance piece.At present, on the one hand, be subject to hydrogen sulfide during common hard electrode operation and corrode and cause hard electrode damage, cause the construction operation failure; On the other hand, because the insulation materials coefficient of expansion and the metal material of the outer parcel of hard electrode are inconsistent, cause hard electrode to be heated in the down-hole and produce the slit between back outer layer insulation material and the metal material, water and mud are invaded the slit, thereby cause hard electrode insulation performance to descend, cause hard electrode damage and well logging construction failure.Yet at present, hard electrode hydrogen sulfide corrosion-resistant and insulating properties are relatively poor, and glued joint and stubbornly refuse to safeguard also that detachably service life of equipment is low, and economic loss is big, the well logging inefficiency.
Summary of the invention
But the purpose of this invention is to provide a kind of simple in structure, easy to use, long service life, high efficiency and the detachable hard electrode of safeguarding of maintenance type.
For achieving the above object, but the hard electrode of the present invention's maintenance type mainly formed by top connection, main body, connector and the lower contact of fixedlying connected with connector, lock shaft is fixedly connected on the main body, and places the inboard of main body and connector; Insulation sleeve is sleeved on the lock shaft, and places the inboard of main body and connector; Felt pad is sleeved on the outside of insulation sleeve, and places between main body and the connector; Dead ring is sleeved on the outside of main body, felt pad and connector, and places between main body and the connector.
But the hard electrode of the maintenance type outside is set with the shell of anti-hydrogen sulfide gas.
Lock shaft is fixedly connected in the top connection by screw thread, and the two detachably separates.
Lower contact is fixedlyed connected by screw thread with connector, and the two detachably separates.
But after adopting the hard electrode of the present invention's maintenance type, because dismountable dead ring, felt pad, insulation sleeve are installed, the insulating properties of hard electrode have been ensured between main body and connector.Can prevent the hard electrode of hydrogen sulfide corrosion but the hard electrode of the maintenance type outside is set with the shell of anti-hydrogen sulfide gas, improve application life.Lock shaft is fixedly connected in the top connection by screw thread and detachable the separation, and lower contact and connector are fixedly connected and detachably separate by screw thread, make hard electrode replaceable safeguard, uses more conveniently, has improved operating efficiency.
Description of drawings
But Fig. 1 is the structural representation of the hard electrode of maintenance type.
Top connection 1, main body 2, dead ring 3, felt pad 4, insulation sleeve 5, lock shaft 6, connector 7, lower contact 8.
The specific embodiment
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
With reference to accompanying drawing, but the hard electrode of a kind of maintenance type mainly formed by top connection 1, main body 2, connector 7 and the lower contact 8 of fixedlying connected with connector 7, lock shaft 6 is fixedly connected on the main body 2, and places the inboard of main body 2 and connector 7; Insulation sleeve 5 is sleeved on the lock shaft 6, and places the inboard of main body 2 and connector 7; Felt pad 4 is sleeved on the outside of insulation sleeve 5, and places between main body 2 and the connector 7; Dead ring 3 is sleeved on the outside of main body 2, felt pad 4 and connector 7, and places between main body 2 and the connector 7; But the hard electrode of the maintenance type outside is set with the shell of anti-hydrogen sulfide gas; Lock shaft 6 is fixedly connected in the top connection 1 by screw thread, and the two detachably separates; Lower contact 8 and connector 7 are fixedlyed connected by screw thread, and the two detachably separates.
During installation, dead ring 3 is sleeved on the main body 2, felt pad 4 is installed in the endoporus of dead ring 3, insulation sleeve 5 and lock shaft 6 are respectively installed in the endoporus of connector 7, outer button with lock shaft 6 is screwed in the interior button of main body 2 then, between dead ring 3 and connector 7, do not have the slit, again lower contact 8 is screwed in the interior button of connector 7, prevent the shell of hydrogen sulfide gas at last at hard electrode outside suit.
Claims (4)
1. but the hard electrode of maintenance type mainly is made up of top connection, main body, connector and the lower contact of fixedlying connected with connector, and it is characterized in that: lock shaft is fixedly connected on the main body, and places the inboard of main body and connector; Insulation sleeve is sleeved on the lock shaft, and places the inboard of main body and connector; Felt pad is sleeved on the outside of insulation sleeve, and places between main body and the connector; Dead ring is sleeved on the outside of main body, felt pad and connector, and places between main body and the connector.
