METHOD OF DETERMINATION OF LOW-PERMEABILITY BEDS IN WELL BEING DRILLED |
摘要 |
FIELD: oil-and-gas industry.SUBSTANCE: background gamma-ray logging is effected to inject tagged drilling solution and to reciprocate drilling equipment. After reciprocation of drilling equipment, 0.5 mof drilling solution are injected with radon concentration making at least 0.175 Gbc per 100 m of well interval to penetrate it additionally. Research interval is flushed in two cycles of circulation to make gamma-ray logging thereafter. Obtained result is compared with background measurement.EFFECT: determination of low-permeability beds. |
