When it comes to the development and application of flip-plate hydraulic oscillating Nw tube shoes, we must first note that the vibration pulse technique has been widely used in different kinds of production areas, especially in the construction industry when pouring concrete , The use of this technology is to clear the honeycomb holes will make the cement cemented directly.
Furthermore, the ability of a flip-plate hydro-oscillating Nw Casing Shoe Bit to increase the strength of the cement between its concrete particles and its concrete and rebar as the material itself has. In fact, we should also pay attention to the fact that the vibration technology used on the flip-plate Nh casing shoes during the cementing process can increase the strength of the cement itself; moreover, in fact, It is to pay attention to it that it can reduce the liquid viscosity and improve cementing displacement efficiency.
In addition, the flip plate hydraulic oscillation Nw Casing Shoe Bit used in the drilling time, which is to shorten the waiting time of cement slurry; in the cement waiting time, which will make the slurry itself is to maintain a certain Of the total liquid column pressure, in addition, it is itself can reduce the slurry static force.
Finally flip the plate hydraulic oscillation Nw Casing Shoe Bit to a certain extent, that is, when the cement casing can replace the upper and lower activities. Vibration cementing tools according to the principle of action will be divided into mechanical, magnetostrictive or piezoelectric ceramic and air compressor type and its hydraulic pulse.
In terms of the current form, the most widely used type of Nh sleeve shoe is the hydraulic pulse vibration cementing. On the flip plate hydraulic oscillation Nw Casing Shoe Bit applied to this type of technology, that is, by changing the fluid flow cross-section, so that it itself will produce periodic pulsating force, it should be noted that there will be reciprocating Vibrating device, the cost will be higher.
