Description
Technical field
The present invention relates to a kind of petroleum drilling engineering technology, in particular to a kind of self-compensating pressure formula pressure difference injection particle
It is continuously injected into method.
Background technique
Particle impact drilling technology is raising one of deep-well/ultradeep well and the effective way of hard formation bit speed, and grain

The heart be how by steel particle with certain rate, be continuously injected into cleaner for high-pressure drilling fluid.
Currently, existing particle injection device still cannot really realize being continuously injected into for particle both at home and abroad, even if using
Dual Implantations pipe injection device, there is also apparent disadvantages in.In two pipes alternating, low-voltage tube has a boost process,
When being just switched on low-voltage tube, it can not be normally carried out spraying operation because pressure declines to a great extent, and low pressure pipe pressure rises to stable work
A period of time is needed as pressure, so that spraying operation is there is interruption, it cannot be guaranteed that particle punching drilling system continuously works always.
When the systems are operating normally, the particle in pressure pan enters mixing chamber from feeder pipe with certain speed, works as particle
When shut-off valve is closed suddenly, due to the effect of inertia, particle still falls, and particle is caused to be compacted in feeder pipe, later, system
Pressure reduction, due to volume effect, pressure pan and its internal water restore flexible deformation, i.e. pressure pan volume contraction and water
Volume expansion leads to particle continued compaction in feeder pipe, eventually leads to the tight of feeder pipe so that the space of entire pressure pan reduces
It blocks again, and solids itself poor flow quality, it is easy to the accident of particle discharge port blocking occur, and de-plugging is difficult.Institute
With, in system stalls, the pressure in pressure pan should be laid down in time, avoid generating volume effect, and relief valve is installed
Be it is worthless, not only cause the inconvenience of operation in this way, but also pressure pan caused an accident when discharging tens of megapascal pressure
Hidden danger.
During particle punching drilling, it is desirable that particle must be uniformly injected into high voltage charge with fixed volume ratio
Converge, and the concentration of particle can be continuously adjusted, common screw extrusion type injection mode because the leakproofness of screw extruding device is poor,
And serious wear, and limit its popularization and application.Above-mentioned situation seriously constrains the commercialization process of particle impact drilling technology,
Particle injection device there are the problem of be badly in need of solve.
