摘　　要：钻井液池体积参数变化是钻井液液量增加或减少的直接显示,也是判断和预防溢流、井漏的关键参数。由于钻井液液面受搅拌器搅拌的影响,波动剧烈,给综合录井仪钻井液池体积参数准确监测造成一定的干扰,影响到溢流和井漏等工程异常的判断,也是录井作业的一个难点。为此,研发了钻井液罐液面抗波动装置,该装置由镂空式抗波动管、安装卡箍、传感器安装支架3部分构成,可大幅减少钻井液搅拌器的影响。通过现场在同一窗口安装两个同型号传感器进行监测对比得知,钻井液罐液面抗波动装置有效地降低了液面波动干扰,提高了溢漏等关键井控异常监测的精确性,为钻井工程实时决策提供了科学依据,为确保井控安全发挥了重要作用。The change of drilling fluid volume parameter is a direct indication of the increase or decrease of drilling fluid found in time,and is also a key parameter for judging and preventing overflow and circulation loss.As the drilling fluid is stirred by the agitator,the liquid level fluctuates violently,which causes certain errors in the monitoring of drilling fluid volume parameter by the comprehensive mud logging unit,and affects the abnormal judgment of drilling fluid parameters such as overflow and circulation loss,which is also a difficult point in the mud logging operation.Therefore,a drilling fluid tank liquid level anti⁃fluctuation device has been developed,which is composed of hollow anti⁃fluctuation pipe,installation of collar clamp,sensor mounting bracket and other components,which can greatly reduce the influence of drilling fluid agitator.By installing two sensors of the same model at the same window on site for monitoring and comparison,it is found that the anti⁃fluctuation device for the drilling fluid tank liquid level effectively reduces the interference of liquid level fluctuations,improves the accuracy of monitoring key well control parameters such as overflow and circulation loss,provides a scientific basis for real⁃time decision⁃making in drilling engineering,and plays an important role in ensuring well control safety.
