Description
Technical field
The utility model belongs to oil and gas well drilling technical field, measures pipe nipple more particularly to a kind of underground vibrating
Background technique
In drilling process, the friction between the impact on drill bit and stratum, the eccentric drilling of drill bit, drill string and the borehole wall is touched
It hits, can all generate strong vibration.Vibration signals of drilling rod contains a large amount of drilling condition information, by acquiring these vibration numbers
According to analysis drillstring vibrations mechanism simultaneously makes reasonable fault diagnosis, for reducing drilling failure, optimization drilling parameter, improving and bore
It all has very important significance into speed.Foreign countries have begun to the research of vibration measurement technology early in the 1960s
And plentiful and substantial technological achievement is achieved, it is domestic that the achievement master in the 1980s, obtaining is started to underground vibrating survey quantifier elimination
If there are no practical underground vibrating measuring tools, relatively external by establishing ideal model and theoretical calculation is obtained
There are also quite poor away from.
Utility model content
Novel purpose is proposing a kind of underground vibrating measurement pipe nipple
New content: a kind of underground vibrating measurement pipe nipple, including nipple body, lower contact, top connection, hollow pipeline are short

Circuit element placed cavity
Further scheme battery placed cavity, electronic circuit placed cavity are anti-seismic structure.
Further scheme battery placed cavity, electronic circuit placed cavity are structure as a whole centre by being divided by partition, partition is set
It is equipped with threading hole.
Further scheme battery placed cavity, electronic circuit placed cavity are by shatter-proof cavity outer wall, shatter-proof cavity wall and shatter-proof chamber
Buffer layer composition between outer wall and shatter-proof cavity wall.
Further scheme buffer layer is rubber filling layer.
The effect that the utility model provides: by vibration measurement circuit integration to independent pipe nipple, while vibration measurement circuit uses
Independent current source power supply, individual chips carry out data processing, measurement while drilling, bore post analysis, the method and step that the utility model proposes is simple,
It is stability, handling good without changing drill column structure size and current process flows, there is innovative and preferable practical valence
Value.
