| titleOfInvention | Method for cleaning clay drilling mud |
| abstract | This invention relates to the oil and gas industry. The goal is to increase the selectivity and the degree of purification of advanced clay drilling mud (GB) due to the enlargement of fine particles of its solid phase. For this, a reagent-flocculant is first prepared, for which a mixture of surfactants sulfonol and emultal surfactants in a ratio of 1: 3 to 1: 5 is used. Then this mixture is introduced into the circulating GBR. In an amount of 0.3-0.5% of the volume of GBR. Thereafter, the drill cutting is mechanically separated. 4 tab. and |
