发明名称 WATER LOSS CONTROL METHOD FOR CIRCULATING FLUID
摘要 FIELD: oil and gas industry.SUBSTANCE: while implementing the method, when producing formation is drilled from access point of the rock cutting tool, in circulating system of the well moisture and density of circulating fluid are measured simultaneously and continuously, against these measurements current volume content of free water is calculated for circulating fluid as per the specified formula, and water loss is defined with well deepening against difference in volume content of water for circulating fluid at inlet into the drilled formation and at outlet from it.EFFECT: increased information content and control authenticity, reduced time and labour costs for performance of auxiliary operations.
