Combined type sensor devices and quantitative degassing apparatus

Abstract

The invention is a composite sensing device and its quantitative degas device. The density sensor and the temperature sensor connect with the detecting container, the slurry pump transmits the waiting detected well liquid by the conveying tube, and the conveying device connects the quantitative degas device. The quantitative box of the degas device is set at the bottom of the degasser, and the bottom of its side wall has the inlet snout and connects the conveying tube, the bracket is on the quantitative box and has the tray of degasser, and the tray has the limiting slurry inlet, the conductive sensing device is equipped on the bracket and can contact the raw liquid position of the quantitative box. The invention can online correctly detects the density of the well liquid, the conductive ratio and the temperature.

Description

technical field [0001] The invention relates to a sensor, especially a sensor device for detecting mud well conditions. Background technique [0002] The well known device for oil drilling exploration record well conditions, such as Chinese patent 00225142.6 discloses a high-precision fluid density on-line measuring instrument consisting of a base, a fluid inlet pipe, a fluid outlet pipe, an inlet hose, an outlet hose, a fluid Flow tube, load cell, intermediate force transmission part and measurement indicator head are connected. When used at the construction site, the measured fluid is passed through the fluid inlet pipe, passes through the inlet hose, the fluid flow pipe, the outlet hose, and finally flows out from the fluid outlet pipe. [0003] As another example, Chinese patent 00230159.8 discloses a mud logging mud density sensor, which is provided with a left gas collector and a right gas collector in its structure, the lower end of the gas c...

Problems solved by technology

[0005] The known sensor devices for detecting mud well conditions, including the aforementioned density sensors, have high requirements for industrial and mining conditions, and it is difficult to fully meet the actual operation, so it affects the accuracy of its measurement of mud density; and the conventionally used density sensor , temperature sensor, and conductivity sensor are respectively installed in the mud tank or grit chamber, which not only has poor detection accuracy and is easily damaged, but also brings inconvenience to installation, use and maintenance. The industry urgently needs a density sensor, temperature sensor, conductivity sensor Integrate the sensor into one, the detection is accurate and strong, it is not easy to be damaged, and the mud well condition detection sensor device that is easy to install and maintain comes out
