Embodiment 1
[0026] A novel high-temperature and high-pressure lithology density probe, comprising a density probe upper joint, a density probe main body, a density probe lower joint, and a ray detector, wherein the density probe upper joint, the density probe main body, and the density probe lower joint are connected in sequence, and the The radiation detector is arranged inside the main body of the density probe.
[0027] The ray detector is mainly composed of a density detector and a preamplifier circuit, a receiving crystal with a long density distance, a photomultiplier tube with a long density distance, a receiving crystal with a short density distance, and a photomultiplier tube with a short density distance.
[0028] The lower joint of the density probe is provided with Cs 137 Density source chamber.
[0029] The density probe is made of high-density material, and the above-mentioned ray detector is built in, and the upper and lower sides are connected with the main body of the de...
Embodiment 2
[0032] A novel high-temperature and high-pressure lithology density probe, comprising an upper cap, a pressure-bearing shell, a lower joint, a lower cap, an electronic circuit core, and a vacuum flask; the upper cap, pressure-bearing shell, lower joint, and lower cap are connected in sequence; The electronic circuit core and the thermos bottle are sequentially plugged and set in the pressure-bearing shell of the instrument.
[0033] A pressure plate is arranged between the end face of the thermos bottle and the end face of the lower cap.
[0034] 11 The upper cap and the 15 lower cap are used for hoisting and transporting the instrument to protect the instrument; 12 The pressure-bearing shell is used to ensure the pressure resistance index of the instrument, 206Mpa; 16 The electronic circuit core is built in the 17 thermos bottle, and the whole is built in the 12 pressure-bearing shell. The lower end of the pressure-bearing shell is sealed by 13 lower joints and 14 pressure-be...
Embodiment 3
[0036] A novel high temperature and high pressure lithology density probe, comprising an upper cap, a lower cap, an upper joint, a density probe, a lower joint, and a main body; the upper cap, upper joint, main body, lower joint, and lower cap are connected in sequence; the density Both ends of the probe are hinged on the main body.
[0037] The two ends of the density probe are respectively hinged with an upper connector and a lower connector, and the upper and lower connectors are hinged to the main body. An electronic circuit core is arranged inside the main body. It also includes a hose, the density probe is connected to the electronic circuit core through a cable, and the cable is covered with a hose. The main body is provided with a groove for accommodating the density probe, the upper connecting body and the lower connecting body. When the density probe, the upper connecting body and the lower connecting body are placed in the groove, the overall diameter thereof is co...
