Изобретение относитс  к технологии освоени  скважин и интенсификации иритока нефти из продуктивного пласта.The invention relates to the technology of well development and the intensification of oil flow from the reservoir.

Известны способы обработки призабойиой зоны карбонатного пласта путем закачки в него растворител  карбонатной породы 1, 2.Known methods of treating the near-bottom zone of the carbonate reservoir by pumping into it the solvent of the carbonate rock 1, 2.

Недостатками таких способов  вл етс  интенсивна  коррози  подземного оборудовани  и недостаточно глубокое проникновение активного агента в обрабатываемый пласт особенно при температурах 100°С и более.The disadvantages of such methods are intensive corrosion of underground equipment and insufficiently deep penetration of the active agent into the treated formation, especially at temperatures of 100 ° C or more.

С целью обеспечени  более глубокого проникновени  реагента в пласт и повышени  производительности скважины в качестве растворител  примен ют раствор динатриевой соли этилендиаминтетрауксусной кислоты.In order to provide a deeper penetration of the reagent into the formation and increase well productivity, a solution of ethylenediaminetetraacetic acid disodium salt is used as a solvent.

Поскольку растворимость динатриевой соли этилендиаминтетрауксусной кислоты при 20°С не превышает 100 г/л, то при использовании более концентрированных растворов сначала готов т 10%-ный раствор, а затем в него дополнительно ввод т необходимое количество кристаллов указанной соли. В процессе дальнейшего нагревани  и перемешивани  при прокачке по насосно-компрессорньш трубам они раствор ютс , создава  требуемую концентрацию раствора.Since the solubility of ethylenediaminetetraacetic acid disodium salt at 20 ° C does not exceed 100 g / l, using more concentrated solutions, a 10% solution is first prepared, and then the required amount of crystals of this salt is additionally introduced into it. In the process of further heating and stirring when pumping through the tubing, they dissolve, creating the desired concentration of the solution.
