Abstract

An interconnector for connecting downhole instruments includes a male connector assembly and a female connector assembly. The male connector assembly has a first housing and a male rotatable connector that are connected together. The female connector assembly has a second housing and a female rotatable connector. The second housing is adapted to receive the female rotatable connector. The male rotatable connector has a first end having a plurality of cylinders that are sequentially and concentrically connected, and a second end adapted to receive a first plurality of electrical wires, and a first plurality of electrical contacts disposed on the plurality of cylinders. The female rotatable connector has a first end having a cavity having a plurality of steps adapted to receive the plurality of cylinders in the male rotatable connector, and a second end adapted to receive a second plurality of electrical wires.

Claims (17)

1. An interconnector for connecting downhole instruments, comprising:

a male connector assembly and a female connector assembly,

wherein:

the male connector assembly comprises a first housing and a male rotatable connector that are connected together,

the female connector assembly has a second housing and a female rotatable connector, wherein the second housing is to receive the female rotatable connector,

the male rotatable connector has a first end comprising a plurality of cylinders that are sequentially and concentrically connected, and a second end to receive a first plurality of electrical wires, a first plurality of electrical contacts disposed on the plurality of cylinders, and

the female rotatable connector has a first end having a cavity having a plurality of steps to receive the plurality of cylinders in the male rotatable connector, and a second end to receive a second plurality of electrical wires,

the male connector assembly is to be connected to a first end of a downhole instrument of the downhole instruments; and the female connector assembly is to be connected to a second end of the downhole instrument of the downhole instruments, and

the downhole instrument is selected from a directional sensor, a pulser, a Gamma probe both non-focused and focused, a battery, an alternator, a gyroscope, a vibration monitor, a pressure sensor, an electromagnetic (EM) telemetry, resistivity sensor, a nuclear logging tool, and a sonic/acoustic sensor.

2. The interconnector of claim 1 , further comprising one or more centralizers affixed to an outer surface of the second housing.

3. The interconnector of claim 2 , wherein each of the one or more centralizers have one or more holes, each hole of the one or more holes receives a screw, a metal disk covering a top of the screw, and a filler sealing the one or more holes.

4. The interconnector of claim 1 , wherein the male connector assembly and the female connector assembly are to be connected together by a tubular fastener.

5. The interconnector of claim 1 , wherein the female rotatable connector is fastened to the second housing by a cap.

6. The interconnector of claim 1 , wherein the male connector assembly further comprises a first machine key affixed to the second end of the male rotatable connector, a second machine key affixed to a first end of the first housing, and a split coupling to receive the first machine key and the second machine key so as to form a connection between the male rotatable connector and the first housing.

7. The interconnector of claim 6 , wherein the first machine key is made from an epoxy resin.

8. A downhole instrument module, comprising a first downhole instrument connected to the interconnector of claim 1 .

9. The downhole instrument module of claim 8 , wherein the first downhole instrument is selected from a directional sensor, a pulser, a Gamma probe both non-focused and focused, a battery, an alternator, a gyroscope, a vibration monitor, a pressure sensor, an electromagnetic (EM) telemetry, resistivity sensor, a nuclear logging tool, and a sonic/acoustic sensor.
