Infrared thermometer is very sensitive to temperature, with high concentration, the temperature measurement range can be controlled within the range of 3 mm in diameter, and the temperature measurement distance can reach more than 10 meters. Temperature and its changes, so as to diagnose the problems of the equipment, and provide a reliable guarantee for preventing hidden dangers of equipment accidents. On the basis of on-site practice, technicians and worker technicians of Shengli Oilfield Gudong Oil Production Plant successfully used it to find pipeline leakage points and find abnormalities in electrical equipment, which brought many conveniences to the oilfield development site process and equipment management, and greatly reduced the workload. , reducing the difficulty of management.
Kiểm tra cho rò rỉ với một nửa nỗ lực
For a long time, the single-well pipeline for polymer injection have often been punctured, leaked and perforated. Some of the thủng points are at a depth of 30-100 cm below the cement floor inside and outside the building of the polymer injection station. In order to repair the the thủng point, it is first need to find the thủng point point.
Cảm hứng bởi các độ nhạy nhiệt độ của hồng ngoại nhiệt kế, the kỹ thuật viên of Gudong Third Mining Center khéo léo used the thermometers to quick and precisionly find the thủng point of pipelines under the cement floor inside and outside the station, achieving twice the result with half the effort.
Dưới bình thường hoàn cảnh% 2c cái gì là vận chuyển đến đầu giếng in đường ống đường ống polymer tiêm giếng là a hỗn hợp của polymer mẹ rượu và nước thải% 2c và nhiệt độ là khoảng 40 độ đến hạn đến khác nhau độ độ độ nén và mật độ của dưới lòng đất lớp lớp bên dưới kích thước của lỗ chân lông là cũng khác nhau. The mixed solution from the leaking point migrates along the point with the highest porosity, turns and extends, and can be transferred for a maximum length of more than 10 meters. Then overflow from the weakest point, the overflow point. During the transfer of the mix, the temperature dầnfrom reductions, is, the overflow point has the lowest temperature, while the thủng point.
Therefore, when actually looking for leaks, as long as you hold the thermometer and move the thermometer along the path of temperature increase from the overflow point, as you approach the leak point, the temperature displayed by the thermometer will gradually increase until it reaches the highest temperature. Find the highest temperature point and find the puncture point. Multiple leak-finding tests have proved that using a thermometer to find puncture points saves time and effort, and the accuracy is 100 percent . This method can greatly reduce the scope of smashing the cement ground, reduce labor intensity and downtime of the polymer injection well, and improve work efficiency.
Kể từ đó 2009, the trên gợi ý đã được sử dụng to find leaks for 15 well times, with a success rate of 100 percent , shortening the pipeline processing time by 6 hours/well time on average, increasing the injection volume of polymer solution by 680 cubic meters, and reducing the time of shutting down for polymer injection.
At around 9 am a few days ago, the temperature in the polymer injection pump room was as high as 30 degree . Wang Laiqing, the station manager and worker technician of the No. 8 injection station, started to inspect the injection equipment one by one with an infrared thermometer in his hand. Suddenly, he found that the crankcase temperature of a polymer injection pump was 2 degree higher than the previous day. If this hidden danger is not eliminated in time, it will directly endanger the normal operation of the polymer injection pump. So, he immediately set out to find out why. Analyzing that the operating frequency of the equipment has not changed, and checking that the motor current has not changed from the past, the possible temperature rise caused by the increase in equipment load has been ruled out, so he looked up the record of adding lubricating oil and asked about the situation of adding lubricating oil at that time. It turned out that the label of lubricating oil added was wrong. With the replacement of lubricating oil, the hidden danger of accident was eliminated in time.
Now, due to the reduction of the injection volume of the mother liquid in the polymer injection well, the operating frequency of the polymer injection pump is low, and some pumps operation at a frequency of about 18 Hz, which causes the motor to heat up and the temperature of the lucating oil in the cacte to be high. Nhiệt độ của một số động cơ vỏ bọc là gần đến 60 độ % 2c và nhiệt độ của bôi trơn dầu in the cacte is also above 50 độ % 2c cái nào mang lại tuyệt vời ẩn nguy hiểm đến dài hạn đáng tin cậy hoạt động của the thiết bị. Do đó, công nhân công nhân sử dụng nhiệt kế đến chuyên sâu kiểm tra nhiệt độ của động cơ vỏ% 2c vòng bi và khác nhau bộ phận of the cacte of the polymer injection pump every day, and make records, and do the following "heatstrokeion prevention and cooling" work for the equipment in time.
One is to open the doors and windows of the pump room to speed up the air convection in the pump room and prevent the temperature rise of the motor and cacte from being too high. The second is to take measures to remove the valve to boost the pump speed and reduce the low-speed operation of the motor. The third is to explore a reasonable lucating oil filling level. Khi nào nó là tìm thấy cái đó nhiệt độ của của bôi trơn dầu in the cacte is quá cao% 2c thêm bôi trơn dầu đến bơm chạy ở thấp tần số đến tăng chất lỏng mức và ngăn chặn nhiệt độ từ tăng quá cao.
