Well sounders «DU-1»
While controlling level, a tested well is to be equipped with an
offset with a valve and an elbow for connecting an echometry
device. Fluid level can be determined only in the space of a well
(tubular, intertubular, annular, borehole annulus) which is
connected with an elbow. The elbow is not to have any abrupt
tapers (chokes, hoppers and similar units).The elbow of the offset
should have pipe tapered thread 60 (State Standard 633-80) and be
located at the height 0.2-1.8 meters above the ground. If the height
exceeds 1.8 meters, fixed or portable platforms are to be used
provided they comply with the Safety Regulations in Oil and Gas
Industry. The elbow which is not used is to be closed with an end
cap. Along the travel path of the sound pulse, there should be no
more than two 90⁰ pipe bends at the distance of 20 meters from the
elbow.
