The present invention provides an experimental apparatus and a method for
petroleum pipe scaling and
wax precipitation, the apparatus comprises a
liquid storage tank, a variable frequency motor, a
screw pump, a constant temperature water bath tank, a first
test tube, a second
test tube, a cover plate and a lacing film
test sample. The
liquid storage tank is used for containing
oil water needed for the experiment, and is connected with a
temperature control system and a heater to ensure
oil water temperature is constant at a preset value; a predetermined flow rate of oil output can be achieved by the variable frequency motor and the
screw pump, the constant temperature water bath tank is used for
simulation of
test tube section wall temperature to study changing laws and mechanisms of
sediment characteristics along with
pipe wall temperature differences; the first test tube is a full size
pipe segment, and is used for fully simulating pipe scaling and
wax precipitation, and the second test tube is a pipe segment with an opening, and is used for study on the laws and mechanisms of the
sediment characteristics along with time. The experimental apparatus and method can provide new methods and supports for research and development and evaluation of measures scaling and
wax removal and prevention, and can ensure the
petroleum pipe safe, economic and efficient operation.
