Stainless steel pipe hydraulic precision control pipeline
1) 1/8″ hydraulic control pipeline hydraulic control pipeline use description
1/8″ hydraulic control pipeline, also called capillary tube. It is mainly used for downhole capillary pressure measurement in oil and gas fields, that is, temperature and pressure sensors (also called downhole permanent pressure gauges, generally nitrogen cylinders) are run downhole with oil and gas well production strings Several thousand meters deep oil and gas layer, and then connect the 1/8″ hydraulic control pipeline (capillary tube) from the temperature and pressure sensor to the fluorescent display on the ground, so that the downhole temperature and pressure can be transmitted to the ground through the capillary tube and through the ground display The fluorescent screen can read the instantaneous temperature and pressure of the downhole oil and gas layer, so as to realize the real-time monitoring of downhole temperature and pressure. It can also be used for pressure control of surface safety valves and other surface valves, as well as various connecting pipelines for instrumentation control systems of large oil and gas field drilling and oil extraction equipment.
2) 1/4″ hydraulic control pipeline hydraulic control pipeline use description
The 1/4″ hydraulic control pipeline is mainly used for the control of the downhole safety valve and the air release valve of the cable packer in oil and gas wells. That is, the 1/4″ hydraulic control pipeline is connected to the downhole safety valve and the gas valve, and the oil and gas are controlled by pressure on the ground. The downhole safety valve and the cable packer bleed valve are switched on and off. After the set pressure is reached, the oil and gas well downhole safety valve and the cable packer bleed valve are opened at the same time, and the oil and gas well can be produced normally. At the same time, the gas separated by the electric submersible pump can also be discharged from the annulus through the bleed valve. In the event of a blowout or normal shut-in, the pressure of the control pipeline is released, so that the downhole safety valve and the cable packer of oil and gas wells The gas valves are closed at the same time, and the oil and gas well tubing and the circulation channels of the annulus are all blocked, so that the safety of the oil well can be ensured. Of course, the 1/4″ hydraulic control pipeline can also be used for the control of downhole safety valves alone. It can also be used for pressure control of surface safety valves and other surface valves, as well as various connecting pipelines for instrumentation control systems of large oil and gas drilling and oil production equipment.
3) 3/8” hydraulic control pipeline hydraulic control pipeline use description
The 3/8″ hydraulic control line is mainly used to inject chemicals into oil and gas wells. That is, the 3/8″ hydraulic control line is connected to the downhole chemical injection valve, and the scale is removed through the 3/8″ hydraulic control line and the chemical injection valve Chemicals are injected from the ground into the tubing at a certain depth downhole to effectively remove the tubing fouling and ensure the normal production of oil and gas fields. It can also be used for pressure control of surface safety valves and other surface valves, and instrument control systems for large oil and gas field drilling and oil production equipment Of various connecting pipelines.
