Technical Field
The utility model belongs to the field of logging while drilling technology (LWD, logging while drilling) in petroleum and natural gas exploration and development, relates to a near-bit geosteering system, and particularly relates to an insulating structure for a near-bit geosteering tool.
Background
In order to realize signal transmission, the current underground electromagnetic wave instrument needs to be insulated. In electromagnetic wave measurement while drilling, it is often necessary to use an electrically insulated dipole antenna as the transmitting antenna, i.e. it is necessary to cut off the drill rod from the bottom insulation with one electrical insulation, forming a dipole transmitting antenna. The electrical insulation is on the one hand required to be electrically insulating and on the other hand required to be able to withstand tensile, compressive and torque forces as part of the drill rod. The quality of the insulation performance relates to the quality of the data transmission.
At present, the general structure adopted by the electromagnetic wave while drilling insulation at home and abroad is as follows: the insulating nipple is formed by connecting an upper metal joint and a lower metal joint through threads, and a connecting gap is reserved between the threads. The double male connector is sprayed with an insulating material (generally ceramic), and the process has extremely high requirements on assembly personnel, and the insulating coating can be damaged when the insulating coating is knocked in the assembly process, so that the insulation is invalid. Meanwhile, when maintaining the junction edge, the spraying time is required to be waited, and the maintenance time and the cost are increased.

In order to achieve the above purpose, the technical scheme of the utility model provides an insulation structure for a near-bit geosteering tool, which comprises a double female connector and a double male connector which are connected with each other, wherein an insulation sleeve for isolating each other is arranged between the double female connector and the double male connector.
Preferably, the insulating sleeve is sleeved on the double male connectors.
Preferably, an outer insulating ring and an inner insulating ring are arranged between the double female connector and the double male connector.
Preferably, the outer insulating ring and the inner insulating ring are located at the outer side and the inner side of the insulating sleeve, respectively.
Preferably, two sides of the outer insulating ring are respectively connected with the double male connector and the double female connector, and a first O-shaped ring is connected with the two sides of the outer insulating ring.
Preferably, a plurality of second O-rings are arranged on the periphery of the inner insulating ring, and the second O-rings are correspondingly connected with the double male connector and the double female connector.
Preferably, the surface of the insulating sleeve is provided with threads.
In summary, the utility model has the following beneficial technical effects:
the utility model adopts the insulating sleeve mode to insulate, thereby not only being convenient for assembly, but also shortening the maintenance time and having low cost.
