Particle impact drilling technology is one of effective way of raising deep-well/ultradeep well and hard formation bit speed, and grain
Sub- injection device is the premise and key that particle impact drilling technology is realized, fundamentally, the core of particle injection device research
The heart be how by steel particle with certain speed, be continuously injected into cleaner for high-pressure drilling fluid.
At present, what existing particle injection device still can not be real both at home and abroad realizes being continuously injected into for particle, even if using
Dual Implantations pipe injection device, there is also obvious disadvantage in.When two pipes replace, low-voltage tube has a boost process,
When low-voltage tube is just switched on, spraying operation cannot be normally carried out because pressure declines to a great extent, and low pressure pipe pressure rises to stabilization work
A period of time is needed as pressure, spraying operation is there is interruption, it is impossible to ensure that particle punching drilling system continuously works all the time.
When the systems are operating normally, the particle in pressure pan enters hybrid chamber with certain speed from tremie pipe, works as particle
When stop valve is closed suddenly, due to the effect of inertia, particle still falls, and causes particle to be compacted in tremie pipe, afterwards, system
Pressure reduction, due to volume effect, pressure pan and its internal water recover elastic deformation, i.e. pressure pan volume contraction and water
Volumetric expansion so that the space of whole pressure pan reduces, and causes particle continued compaction in tremie pipe, ultimately results in the tight of tremie pipe
Block again, and solids itself poor flow quality, it is easy to there is the accident of particle discharging opening blocking, and de-plugging is difficult.Institute
In system stalls, the pressure in pressure pan should be laid down in time, it is to avoid produce volume effect, and install relief valve
It is worthless, so not only causes the inconvenience of operation, and cause that pressure pan produces accident when tens of MPas are discharged
Hidden danger.
