摘　　要：录井现场缓冲罐内钻井液液面常随着泵排量、井底复杂情况的变化及一些人为因素影响而上下波动,为了使脱气器能够稳定脱气,需要根据钻井液液面变化对其进行人工调节。否则,钻井液液面过高易造成抽钻井液堵塞气管线,烧毁电机;钻井液液面过低脱不到钻井液,导致丢失气测数据。为节省人力、保证气测数据的准确性和及时性,研发了全自动液位自调式脱气器,可通过超声波液位传感器对液面高度进行测量,进而驱动电机对脱气器吃液高度上下调节,自动应对缓冲罐内液面起伏、钻井液气泡过多等复杂情况。与传统脱气器相比,全自动液位自调式脱气器改变了调节驱动模式,实现了脱气器吃液高度自动调节,从而降低了劳动强度,提升了设备运行可靠性和本质安全,提高了气测录井数据的质量。The drilling fluid level in the buffer tank at the mud logging site often fluctuates up and down with the changes of pump displacement and bottom-hole complex situations,and the influence of some human factors.In order to stabilize degassing,the degasser needs to be manually regulated according to the changes of drilling fluid level.Otherwise,if the drilling fluid level is too high,it may cause the pumping drilling fluid to block the gas pipeline and burn the motor.If the drilling fluid level is too low to degas the drilling fluid,resulting in the loss of gas logging data.In order to save manpower and ensure the accuracy and timeliness of gas logging data,the full automatic level self-regulating degasser has been researched and developed,which can measure the level height through the ultrasonic liquid level sensor,then drive the motor to regulate the liquid intake height of the degasser up and down,and automatically deal with the complex situations such as level heave and excessive drilling fluid bubbles in the buffer tank.Compared with the traditional degassers,the full automatic level self-regulating degasser changes the regulation drive mode,realizes automatic regulation for the liquid intake height of the degasser,thereby reducing labor intensity,improving equipment operation reliability and inherent safety,and enhancing the quality of gas logging data.
