Embodiment 1

[0027] A logging-while-drilling tool equipped with a flow path conversion connector, such as Figure 1-Figure 5 As shown, it includes a connecting male sleeve 1, a connecting block 2, a fluid transition installation block 3 and a connecting female sleeve 4. A mud channel 101 is opened in the middle of the connecting male sleeve 1, and a connecting block 2 is fixedly connected to the left part of the connecting male sleeve 1. The outer surface of the right part of the block 2 is threaded, and the middle part of the connecting block 2 is provided with a first buffer distribution chamber 201. The diameter of the left part of the first buffer distribution chamber 201 of the connection block 2 is larger than the diameter of its right part. The first buffer distribution chamber 201 and The mud channels 101 are connected, and the left part of the connecting block 2 is slidingly provided with a fluid transition installation block 3. The middle part of the fluid transition installation ...

Embodiment 2

[0032] On the basis of Example 1, such as figure 2 , Figure 4 and Figure 5 As shown, it also includes a U-shaped sealing ring 5 and a sealing gasket 6. The U-shaped sealing ring 5 is embedded in the inner side of the right end of the connecting female sleeve 4. The sealing gasket 6 is arranged between the connection block 2 and the fluid transition installation block 3. The sealing gasket 6 The cross-sectional shape is the same as the shape of the left end surface of the connecting block 2, and the U-shaped sealing ring 5 and the sealing gasket 6 are made of soft materials.

[0033] Such as figure 2 and Figure 5-Figure 8 As shown, it also includes an auxiliary installation nozzle 7, a wedge block 8 and a spring 9, the auxiliary installation nozzle 7 is set on the inner right part of the connecting male sleeve 1, and the left side of the auxiliary installation nozzle 7 is provided with eight limit positions Groove 701, the right part of the outer surface of the auxilia...

Abstract

The invention relates to the technical field of logging-while-drilling instruments, in particular to a logging-while-drilling instrument provided with a flow channel conversion connecting piece. The technical problem to be solved is to provide the logging-while-drilling instrument provided with the flow channel conversion connecting piece, which has a uniform shunting effect. The logging-while-drilling instrument comprises a connecting male sleeve, a connecting block, a fluid transition mounting block, a connecting female sleeve and the like, a connecting block is fixedly connected to the left portion of the connecting male sleeve, a fluid transition mounting block is slidably arranged on the left portion of the connecting block, and a connecting female sleeve is slidably arranged on the left portion of the fluid transition mounting block. Through the application of the circulation buffer channel, the first buffer distribution cavity and the second buffer distribution cavity, the connecting piece disperses and transmits slurry, generation of vortexes is reduced to a great extent, backward dispersive transmission of the slurry is further assisted through distribution of the slurry distribution outlets, direct impact on a measurement module is reduced, and the measurement accuracy is improved. And the erosion phenomenon is reduced, and the service life of the connecting piece is prolonged.

Description

technical field [0001] The invention relates to the technical field of logging-while-drilling instruments, in particular to a logging-while-drilling instrument equipped with a flow channel conversion connector. Background technique [0002] Logging while drilling in the petroleum industry generally refers to the measurement of formation petrophysical parameters during the drilling process, such as the measurement of well deviation, azimuth and tool face, etc., and the measurement results are transmitted to the ground in real time through the data telemetry system for processing. Generally refers to the measurement of drilling engineering parameters. [0003] Logging while drilling is needed in the process of logging while drilling. Different types of logging while drilling tools provide electrical energy and communication signal transmission through wired connections. For the sake of instrument structure and functionality, logging while drilling The line of the well tool is...
