FIELD: oil-and-gas industry.
SUBSTANCE: invention can be used for development of oil fields with a big content of asphaltene, resin and paraffin. To define disposals volume in well tubing, equipped with sucker-rod well pump, fill in sequentially a clearance between tubing pipes and a rod string with liquids of different densities. Define a load on device polished stock after every filling, estimate disposal amount using mathematical correlation.
EFFECT: tubing pipes diagnosing related to disposal grade and timely decision making on ARPD removal from pipes, washing them away with corresponding solvent.
