Embodiment 1
[0021] Such as figure 1 , figure 2 with image 3 As shown, this embodiment provides a non-radioactive density measuring device, including a sand mixing vehicle digital acquisition instrument 2 and a sand mixing tank 1, the outlet of the sand mixing tank 1 is connected to the upstream discharge main manifold 6, and the upstream discharge main manifold 6 is connected to Along with the inlet of the discharge pump 7, the outlet of the discharge pump 7 is connected to the downstream discharge main manifold 16, which leads to the well, and the downstream discharge main manifold 16 is connected to a bypass pipeline 8, which is connected to the mixing tank. At the entrance of the sand tank 1, the bypass line 8 is connected in series with a Coriolis force mass flowmeter 3, and the Coriolis force mass flowmeter 3 is electrically connected to the digital acquisition instrument 2 of the sand mixing vehicle.
[0022] It should be noted that the Coriolis force mass flowmeter 3 is a matur...
Embodiment 2
[0028] On the basis of Example 1, such as image 3 As shown, the Coriolis mass flowmeter includes a transmitter 4 and a flow tube 5, the flow tube 5 is connected in series to the bypass line 8, the flow tube 5 is installed vertically with a straight tube, and the liquid flows from bottom to top. The upper and lower ends of the inner cavity of the flow tube 5 are equipped with detectors 14 for detecting the deformation of the flow tube 5. The detector 14 is electrically connected to the transmitter 4, and the transmitter 4 is installed and connected to a signal converter 9, and the signal The converter 9 is electrically connected with the digital acquisition instrument 2 of the sand mixing vehicle.
[0029] The non-radioactive density measuring device adopts a straight tube structure design, and there are no obstacles or moving parts in the flow tube 5, which greatly reduces the blockage of the flow tube, and is also convenient for self-cleaning after operation and easy mainten...
Embodiment 3
[0033] On the basis of Example 1, such as figure 1 As shown, the bypass line 8 at the inlet end of the flow tube 5 is connected with an inlet ball valve 12 in series, and the bypass line 8 at the outlet end is connected with an outlet ball valve 13 in series. When the Coriolis force mass flowmeter 3 is installed, the flow tube 5 is connected to the bypass line 8 through the flange 15 .
[0034] Non-radioactive density measuring devices are used by:
[0035] After the fracturing preparations are ready, turn on the main power of the equipment on the sand mixer, and then turn on the power of the computer and the digital instrument 2 of the mixer in turn. The system is preheated for 5 minutes. Confirm that the liquid filling ball valve of the Coriolis mass flowmeter 3 is closed, and then start the emptying and pressure test operation according to the construction procedure. After the pressure test is completed, when the replacement operation is ready, first fill the sand mixing t...
