METHOD OF PREPARING SAMPLES OF FORMATION FLUID FOR MOLECULAR BIOLOGICAL ANALYSIS

摘要

FIELD: oil and gas production. ^ SUBSTANCE: proposed method comprises dividing formation fluid into water and hydrocarbon phases to produce solid hydrocarbon scale. Said division is executed by settling formation fluid at +4C for 24-72 hours. Then, water phase centrifugation is carried out at 10000-14000 rpm for 15 minutes to use it for DNA isolation and subsequent molecular biological analysis. ^ EFFECT: higher accuracy and validity. ^ 1 ex, 2 tbl
