Applications "pressurized pipeline opening" on construction,Sucker rods with molded guide the first line in charge of welding flange mounted on the valve. "Pressure pipeline HOLE" is mounted on the valve, through the opening in the competent punch line.
After the punch, close the valve, remove "pressurized pipeline hole saw," Wang line 45 wells by bolting to the valve can be. The whole process without spillage, less than ten minutes.
The invention as compared with conventional construction methods is to install a multi-valve, pipeline welding to Sucker rod pump unit controller change the past, did not affect the production rate and yield when a single well, providing for the oil and gas pipeline risk management, incident handling, environmental pollution control in the new technology options.
