METHOD FOR DETECTION OF SALT DEPOSITION ZONES IN WELL

摘要

FIELD: oil and gas production.;SUBSTANCE: according to pulse neutron logging, neutron medium characteristics are differentiated, including - thermal lifetime in initial τ_i and distant τ_d thermal-neutron decay time areas related to space immediately behind tubing, and in a well zone of the formation.;EFFECT: more efficient operation of oil and gas wells ensured by detection of salt deposit detection on an outer surfaces of the tubing by geophysical methods.;2 dwg
