The general principles
of sucker-rod pumps as used in oil wells are well known. Technical Data used in
the field explained in petroleum
courses in Rawalpindi. Fundamentally, they consist of the usual simple
combination of a cylinder and piston or plunger with a suitable intake valve
and discharge valve for displacing the well fluid into the tubing and to the
surface. However, the variety of problems encountered in pumping oil wells has
resulted in a great number of modifications of this fundamentally simple unit
to make it more effective for the various conditions encountered.
In general, the pumping
of oil wells often presents the widest variety of advise conditions possible in
a single installation of any pumping application. These may include high
discharge pressures; low intake pressures; severe abrasive conditions resulting
from sand or other solids in suspension: severe corrosive conditions resulting
from corrosive gases or salt waters; deposits of lime, salts, or other solids
from the water pumped; paraffin deposits from the oil pumped; and the
requirement that the pump handle liquids, permanent gases, and condensable
vapors under the pressure and temperature conditions existing at the pump.
Strong magnetic forces that may interfere with valve action when the valves are
made of magnetic material are encountered often. And electrolytic corrosion is
likely to occur as a result of using dissimilar materials. Some more details of petroleum courses
in rawalpindi are as under.
The bores of
reciprocating oil well pumps can range from 1 to 4% in. in diameter. The 4X-in.
bore pump has a displacement about 22% times that of the l-in. pump for a given
speed and stroke length. This wide range of pump capacities is necessary to
permit selection of the most efficient and economical pumping equipment for all
conditions encountered. In many wells it is necessary to pump large volumes of
water along with the oil, so the pump must have a capacity several times that
indicated by the net oil production. TSK Training for Skills and Knowledge is
the best institute in Rawalpindi Islamabad for Pakistani Students who wants to
join oil field after petroleum courses in Islamabad.
