Relationship between pump pressure and bit pressure drop
Classification and nomenclature. For example, according to the drive method can be divided into electric pumps and water turbine pumps; according to the structure can be divided into single-stage pumps and multi-stage pumps; according to the use of boilers can be divided into feed water pumps and metering pumps; according to the nature of the transmission fluid can be divided into pumps, pumpsAnd mud pumps, etc.. In accordance with the non axial structure, can be divided into linear pumps and traditional pumps. It adopts the principle of magnetic suspension and the hydraulic structure of spiral ring to realize liquid propulsion, that is, to cancel the shaft, to cancel the shaft connection, and to cancel the seal structure of the shaft. After starting, the electric current is transformed into a magnetic field, and the magnetic field force drives the spiral ring to move, namely, the spiral ring promotes the liquid advance.
Liquids such as liquids, liquids, gases, and liquids containing suspended solids. Pump can usually be divided into three types of displacement pumps, power pumps and other types of pumps according to the principle of operation. In addition to the principle of classification, there are other ways
The pump pressure is the total pressure loss of the circulation system, including the ground manifold, the internal pressure loss of the drill pipe, the annulus pressure consumption and the bit pressure drop. A pump is a machine that transports liquids or pumps liquids. It transfers mechanical energy or other external energy of the prime mover to the liquid, increasing the energy of the liquid. Pump is mainly used to transport water, oil, acid and alkali liquid, emulsion, suspension emulsion and liquid gold
Bit pressure drop and displacement are related to nozzle size. The greater the displacement, the greater the pressure drop; the smaller the nozzle, the greater the pressure drop.
