Oil pressure definition
The residual pressure after the flow pressure lifts the oil and gas from the bottom of the well through the oil pipe to the wellhead is called the oil pipe pressure, which is called oil pressure. It is measured by the tubing pressure gauge, and its value is the flow pressure minus the column pressure, frictional resistance and slippage loss of the oil and gas mixture in the well. The oil pressure depends on the level of the flow pressure, and the flow pressure is related to the pressure of the reservoir. Therefore, the oil pressure is a reflection of the energy of the well.
