井下重力传感器延时微重力测量能够监测井间流体的运动。地面和井下重力传感器对体积密度变化很敏感,能监测随注入水的运动产生的密度改变,在气液接触面尤其明显。现有的井下重力计采用La-coste-Romberg公司的弹簧式传感器进行固定测量,以3
Downhole gravity sensor delay microgravity measurement to monitor fluid movement between wells. Ground and downhole gravity sensors are sensitive to changes in bulk density and can monitor changes in density as a function of water injection, particularly at the gas-liquid interface. Existing downhole gravimeter La-coste-Romberg company’s spring-loaded sensors for fixed measurements to 3
