Poligr. UP PRL. Naklad 120 §gz.Cena 45 zl PLThe subject of the invention is an agent for the elimination of disappearances and escapes in boreholes, especially in the oil and coal industry. - 5% by weight of polyacrylamide solution added in an amount of 1 - 3% by volume with respect to the bentonite suspension. The disadvantage of this grout is the lack of resistance to washing out and corrosion by bed water due to the long setting time of the sealing mixture. The aim of the invention is to increase the corrosion resistance caused by The essence of the invention is a means for eliminating foulings and escapes in boreholes, which is a mixture containing, in addition to the water suspension of mineral raw materials, aqueous solutions having, in relation to the weight of the mixing water, 1 - 50% by weight of dry weight of acrylic acid and as an initiator 0.001-10% by weight of dry weight of ammonium persulfate and as an activator 0.005-10% by weight of dry weight of triethanolamine, the salts of acrylic acid being magnesium, potassium, sodium, calcium and aluminum, while the mineral raw materials are natural and activated substances, dust volatile, sand, coal dust, post-cement dust and cements with a pH of at least 10. The advantage of the agent for the elimination of disappearances and escapes of muds in boreholes, according to the invention, is the possibility of regulating the density of the agent in the range of 1.0-2.0 g / cm3 by using different amounts of mineral raw materials and accelerating the setting time to 3 minutes by administering different concentrations of initiator and activator. Examples of preparation of a measure to eliminate foulings and escapes in boreholes, according to the invention. Example I, fly ash with a pH of about 10 691.6 kg 29% aqueous solution of the acid magnesium salt Akr5w ^ o * WHr 25% aqueous solution of ammonium persulfate 7.7 kg 25% aqueous solution of triethanolamine 11.1 kg The density of the agent is 1.5 G / c time to solidify> 5 minutes. Example II - with the use of raw materials activated with sodium hydroxide to pH 12 20% by weight water suspension of raw materials ttfct ** 4 * t8% 20% aqueous solution of sodium hydroxide 194.3 kg 29% water solution magnesium salt of acrylic acid 4T ^ ^ 25% aqueous solution of ammonium persulfate 5.4 kg 25% water solution of triethanolamine 9.8 kg The thickness of the agent is 1.181 G / cm \ and the setting time is 10 minutes. Patent claim A measure for eliminating flushing losses and leaks in holes rigs constituting a mixture containing a water suspension of mineral raw materials, characterized in that it contains an aqueous solution containing in the ratio of 236 4 to the weight of water 1-50% by weight of dry weight of acrylic acid salts and 0.001 - WA by weight of dry weight of ammonium persulfate and 0.005-10 '/ c by weight of dry matter of triethanolamine, the salts of acrylic acid being magnesium, potassium, sodium, calcium and aluminum, and the mineral raw materials are natural and activated substances, fly dust, sand, coal dust, sweat dust cementitious, and cements with a pH of at least 10.
