在石油勘探和测井中,现场处理和分析井下泥浆密度、压力、地质等参数,是实现科学和安全钻井、提高工效的有效方法.但我国目前使用的测井仪器多为舶来品,亟待国产化.据此,我们对预报井漏、井喷,判断井下异常现象的泥浆密度传感器进行了研制.1 工作原理及结构1.1 原理液体密度的测量,可根据密度与固定高度间压差的关系,通过差压式敏感元件测得压差值后,经规一化得到相应的密度值.
In oil exploration and logging, on-site processing and analysis of downhole mud density, pressure, geology and other parameters is an effective way to achieve scientific and safe drilling and improve work efficiency. However, logging instruments currently used in our country are mostly imported products and are in urgent need of localization Based on this, we developed a mud density sensor for predicting wellbore leakage, blowout and judging the anomalies in the underground.1 Principle and Structure 1.1 Principle The measurement of liquid density can be based on the relationship between the density and the pressure difference at a fixed height, Pressure-sensitive components measured pressure value, the normalized to obtain the corresponding density value.
