METHOD OF DETECTING ESCAPE OF SAND FROM GAS WELL

摘要

FIELD: investigating or analyzing materials. ^ SUBSTANCE: method comprises setting the rod covered with the adhesive agent in the gas flow. The rod is allowed to stand in the flow for a time interval and then is removed. The adhesive agent together with the adherent particles is then washed out by a solvent, and the solution obtained is filtered. The presence and amount of sediment indicate the fact of sand escaping and its intensity. ^ EFFECT: enhanced reliability. ^ 1 dwg
