Safety production measures for drilling in winter are very important. The measures are formulated for better production, and every detail is very critical and needs to be put in place. Zhong Da Consulting will explain the safety production measures for drilling in winter.

1, strictly adhere to the leading cadre shift system, perform the responsibilities of this position, and supervise and inspect the safety of personnel and equipment in each position during construction; 2. According to the requirements of winter construction, the ground mud pipeline is installed with a slope of 1.5%, so as to discharge the backwater and mud in the pipeline when the circulation is stopped. 3. When all pipes with water and mud meet steam pipes, heat tracing should be installed side by side and wrapped with felt. The driller and anti-collision crown block should be in place, and the steam pipeline and heat sink should be installed in the manifold, control box, oil tank and chemical agent tank. 4. The exposed parts of the valve, gate group and pump group of the mud tank and the bleeding part of the rotary clutch should be insulated to prevent freezing and freezing, and a scavenging pipeline should be installed at the riser. 5. Before starting the pump, preheat the safety valve, pipeline, pump pressure gauge, high pressure valve, faucet and hose, and start the pump only after being confirmed by the driller and assistant driller. 6. Before tripping in, check whether the drilling tools, water holes and Kelly are unblocked. When the water brake is not used, the water should be drained in time to prevent freezing. 7. When tripping in and out, lubricate wellhead tools such as tongs and elevators with engine oil. After pulling out ten columns, confirm that the underground conditions are normal. Remove the hose in time to drain the mud. 8. When Kelly or drill pipe is in the rat hole, it must be steamed to prevent freezing. 9. When all kinds of pipes and pumps are not in use, gas shall be used to sweep away the residual water to prevent freezing. 10, the gas path connector should be drained frequently to prevent the gas path from freezing.
