Embodiment 1
[0046] Such as Figure 1 to Figure 3 As shown, a material tank liquid level dynamic control device of a particle drilling and conveying system includes a material tank 1, a particle feeding control device 6 arranged on the material tank 1, and is arranged in the material tank 1 or in the material tank 1. A hollow U-shaped pipe 3 connected to the material tank 1 outside the tank 1, a liquid level measuring device 4 arranged on the U-shaped pipe 3, a flow control device 5 arranged on the material tank 1, and the liquid level measuring device 4 is used to measure the liquid level of the drilling fluid in the U-shaped pipe 3, the flow control device 5 is used to control the flow rate of the drilling fluid entering the material tank 1, and the particle feeding control device 6 is used to control the flow of the drilling fluid into the material tank 1 The amount of particles added.
[0047] During use, the drilling fluid enters the U-shaped pipe 3 from the bottom of the material tank...
Embodiment 2
[0067] Such as Figure 1 to Figure 3 As shown, as a further optimization of Embodiment 1, this embodiment includes all the technical features of Embodiment 1. In addition, this embodiment also includes the following technical features:
[0068] The control method of the material tank liquid level dynamic control device of the particle drilling delivery system includes the following steps:
[0069] S1, set the rated displacement of the high-frequency drilling fluid delivery pump as Q, the particle concentration in the drilling fluid as P, and the cross-sectional area entering the material tank 1 as S; assuming that within a period of time t, the opening of the opening adjustment valve 51 is Ft , the liquid level in the U-shaped pipe 3 changes Δh, wherein, the starting time of t is t0, the ending time of t is t1, Δh=the liquid level height at time t0-the liquid level height at time t1, then at time After t1, the opening of the opening adjustment valve 51 is adjusted to F=Ft+(S*...
Embodiment 3
[0081] Such as figure 1 As shown, as a further optimization of Embodiment 1 and Embodiment 2, this embodiment includes all the technical features of Embodiment 1 and Embodiment 2. In addition, this embodiment provides a more detailed implementation solution:
[0082] In this embodiment, flow channel adjustment equipment (ie flow control device 5) and a fixed-frequency drilling fluid delivery pump are installed, and the cross-sectional area of the flow channel is changed by the flow channel adjustment equipment, thereby changing the drilling fluid delivery flow. At the same time, combined with the liquid level data in the material tank 1 fed back by the liquid level measuring device 4 in real time, the cross-sectional area of the flow channel is adjusted to maintain the liquid level in the material tank 1 at 700-1000mm, effectively preventing the drilling fluid from spilling.
[0083] This embodiment adopts the differential liquid level dynamic adjustment algorithm to reali...
