摘要 |
FIELD: instrumentation. ^ SUBSTANCE: invention refers to methods of drilled operating wells investigation and can be used for reveal of hydrocarbon-bearing formations directly on completion of their drilling by gamma-ray logging (GR) during well rearrangement. This is achieved by activating tracing fluid with low-active radon in such a view that radon specific activity in tracing fluid would be of 0.37-1.0 MBq/m3. With such radon concentrations, licensing of such works is not required according to radiation safety standards "áæ-99", i.e. they are environmentally safe. At the end of penetration after drill column has been lifted the GR is performed and hydrocarbon-bearing formations are selected according to values of gamma ray intensity exceeding 50 mcR/h. The method features the simplicity of technical execution, use of standard equipment, environmental safety, high sensitivity and reliability. ^ EFFECT: increase in reliability of hydrocarbon-bearing formation reveal from GR which is performed during well drilling. |
