Hydro-mechanical method for tubing string cleaning from asphalting-tar-paraffin crystals
Kh.M. IbrahimovIn the article have been reviewed the measures on tubing string cleaning from asphalt-tar-paraffin sediments formed while oil boreholes exploitation. In order to solve these problems connected with cleaning from asphalt-tar-paraffin crystals and mechanical sediments has been developed a new mechanical device which has been tested in pipe cleaning workshop in OGPD named after N. Narimanov. Test results showed that besides cleaning the pipes from ATP crystals and other mechanic sedimentations the device also prevents roughness of the pipe from inner side and creates smoothness inside the pipe. As a result, sedimentation period of ATP crystals inside the pipe is reduced which leads to increase runtime period between overhaul periods for 1.5-2.0 times.
