Centrifugal Pumps
Centrifugal pumps are the most common types of pumps used in the oil and gas industry. Centrifugal pumps use centrifugal force through the rotation of the pump impeller to draw fluid into the intake of the pump and force it through the discharge section via centrifugal force. The flow through the pump is controlled by discharge flow control valves.
Reciprocating Plunger Pumps
Plunger pumps are some of the most ubiquitous industrial pumps in the oil and gas industry. Plunger pumps use the reciprocating motion of plungers and pistons to pressurize fluid in an enclosed cylinder to a piping system. Plunger pumps are considered constant flow pumps since at a given speed, the flow rate is constant despite the system pressure. A relief valve is an essential part of any plunger pump discharge piping system to prevent overpressuring of the pump and piping system
Progressive Cavity Pumps
A progressive cavity pump is a type of positive displacement pump and is also known as an eccentric screw pump or cavity pump. It transfers fluid by means of the progress, through the pump, of a sequence of small, fixed shape, discrete cavities, as its rotor is turned. Progressive cavity pumps are used in high viscosity applications or if blending the of the pumped fluid is not desired.
Diaphragm pumps
Diaphragm pumps are one of the most versatile types of oil and gas pumps in the industry and transfer fluid through positive displacement with a valve and diaphragm. The working principle of this pump is that a decrease in volume causes an increase in pressure in a vacuum and vice versa.
Gear Pumps
A gear pump uses the meshing of gears to pump fluid by displacement. Gear pumps are one of the most common types of positive displacement pumps for transferring industrial fluids.
Metering pumps
A metering pump moves a precise volume of liquid in a specified time period providing an accurate flow rate. Delivery of fluids in precise adjustable flow rates is sometimes called metering.
Application of Oil Well Pumpjack
Above Ground
In earlier days, the pumpjacks were actuated by the rod lines that used to run horizontally above ground to an eccentric wheel in a mechanism called central power. Central power could operate dozen or even more pumpjacks and it was powered by internal combustion or steam engine or by electric motor. One of the difficulties in this scheme was to maintain the system balance as the individual well loads changed.
Down-hole
There is a down-hole pump located at bottom of tubing. There are 2 ball check valves in this pump. There is a stationary valve located at bottom known as standing valve and there is another valve on piston connected to bottom of sucker rods known as traveling valve. The traveling valve travels up & down as rods reciprocate. The fluid in reservoir enters from formation in to bottom of borehole via perforations which are made through cement and casing. (Casing is the larger pipe of metal which runs through the length of well. Cement is placed between casing and earth; pump, tubing and the sucker are all inside casing).
