| titleOfInvention | Compositions and methods for treatment of oil and gas wells |
| abstract | FIELD: oil, gas and coke-chemical industries. n SUBSTANCE: invention relates to treatment of oil and gas wells. Composition for use in well operations in oil and gas well, containing A. ether, having given formula, in amount of 40–90 wt. %; and B. at least one additional component selected from: (i) ester of given formulas, (ii) alkoxylated alcohol, (iii) mixtures (i) and (ii), (iv) acid and (v) mixtures (i), (ii) and (iv), where ester and alkoxylated alcohol are present in total amount of 0.01 to 5 wt. %. Method of treating a wellbore, comprising: providing a composition containing one of: Composition A consisting of said ester; Composition B consisting of Composition A and at least one of (i), (ii) and (iii); Composition C consisting of Composition A and hydrocarbon cosolvent; Composition D consisting of Composition B and hydrocarbon co-solvent; Composition E consisting of Composition A and acid; Composition F consisting of Composition B and acid; Composition G consisting of Composition C and acid; Composition H consisting of Composition B and hydrocarbon co-solvent; Composition I consisting of Composition F and hydrocarbon co-solvent; where ester and alkoxylated alcohol are present in total amount of 0.01 to 5 wt. %, introduction of at least one of the AI Compositions into the well shaft and performing the operation containing one action from: cleaning the well shaft, removing the filter cake, acid treatment. Invention is developed in dependent items of the formula. n EFFECT: technical result is the increase in the treatment efficiency. n 11 cl, 3 tbl, 1 dwg |
