Description

Изобретение относитс  к области, бурени  нефт ных и газовых скважин, в частности к технологии приготовлени  буровых растворов/ примен емых при проходке нефт ных и газовых скважин .. Известны способы химическрй обработки буровых растворов путем введени  щелочи-ингибированные раство№1 1 Наи более близким к предлагаемсану способу по технической сущности и достигаемс ну результату  вл етс  способ химической обработки буровых растворов путем приготовлени  раствора соли ,, карналлита или бишофита с последующим введением щелочи и- после образовани  гидрогели  магни  в раствор ввод т .реагент-стабилизатор 2. Целью изобретени   вл етс  повышение эффективности способа химической обработки буровых растворов за счет улучшени  антикоррозионных свойств растворов. ; . Это достигаетс  тем, что щелочь ввод т перед введением соли и в качестве соли используют сернокислое железо или сернокислый алк)миний. Способ осуществл етс  следующим образом. Готов т водный раствор щелочи, например едкого натра, извести, затем в него ввод т соль - сернокислое железо или сернокислый алюминий в суЬсом виде или. в виде, растворов. Смесь интенсивно перемешивают до получени . структурированного гел  с водородным показателем рН 7-8 и затем раствор об1забатывают реагентами-стабилизаторами и при необходимости ввод т смазочные и другие добавки. При достижении рН 7-8 введение солей прекращают. В табл I приведены предлагаемые составы растворовf в табл. 2 - свойства предлагаемых pacTBOjaoB.The invention relates to the field of drilling oil and gas wells, in particular to the technology of preparing drilling fluids / used when drilling oil and gas wells. Known methods for the chemical treatment of drilling fluids by injecting alkali-inhibited solutions # 1 1 Most closely The proposed process is technically based and the result is a method of chemical treatment of drilling fluids by preparing a solution of carnallite or bischofite salt, followed by the introduction of alkali and after rofessional hydrogels of magnesium in solution is administered .reagent stabilizer 2. The purpose of the invention is a method for improving the efficiency of chemical treatment of drilling fluids by improving the anticorrosive properties of the solutions. ; . This is achieved by the fact that the alkali is introduced before the introduction of salt and iron sulphate or sulphate is used as a salt. The method is carried out as follows. An aqueous solution of an alkali is prepared, for example, caustic soda, lime, then the salt is added - iron sulfate or aluminum sulphate in bulk or. in the form of solutions. The mixture is vigorously stirred to obtain. A structured gel with a pH of 7-8 and then the solution is treated with stabilizing agents and, if necessary, lubricants and other additives are added. When a pH of 7-8 is reached, the introduction of salts is stopped. Table I shows the proposed composition of the solutions in Table. 2 - properties offered by pacTBOjaoB.
