Description
В авт. св. № 78900 описан способ обнаружени нефтеносных иластов путем измерепи величин электродв::жущи.х сил электрохимического происхождени , возникающих при введении в глинистый раствор химических реагентов.In auth. St. No. 78900 describes a method for detecting oil-bearing ilast by measuring the values of electrodes in the form of forces of electrochemical origin arising from the introduction of chemical reagents into the mud.
Предлагаемое видоизменение способа по авт. св. № 78900 состоит в том, что вместо обработки химическим реагентом всего глинистого раствора примен ют местный подвод реагента к одному из двух электродов , опускаемых в скважину. Дл осуществлени этого способа предлагаетс примен ть аппарат, опускаемый вместе с электродами в скважину, вмещающий реагент и снабженныГ трубкой, подвод щей этот реагент к одному из электродов.The proposed modification of the method according to ed. St. No. 78900 is that instead of treating the entire mud with a chemical reagent, a local reagent supply is applied to one of the two electrodes that are lowered into the well. To implement this method, it is proposed to use an apparatus that is lowered together with the electrodes into the well, containing the reagent and equipped with a tube that supplies this reagent to one of the electrodes.
На фиг. 1 и 2 схематически изображены два варианта такоЧ) ан парата.FIG. Figures 1 and 2 schematically depict two variants of such analogue.
Принцип действи аппарата основан на том, что химические ре акции определенных реактивов создают специфические электродвижущие силы. К одному из двух одинаковых электродов, опускаемых в скважину в одинаковых услови х, подвод тс реагенты, дающие специфические электродвижущие силы при химическом воздействии этих peai eHTOB на нефть, газы, Боду и породы, в которых пробуриваетс скважина. Изменение разности потенпиалов между обоими элехтродами , в зависимости от того, с чем (нефть, газ, породы и пр.) приходит в контакт реагент при прохождении сквал ины. дает указание на наличие в данном .месте скважин 1 нефти, газа, воды или тех или иных пород.The principle of operation of the apparatus is based on the fact that chemical reactions of certain reagents create specific electromotive forces. Reagents are supplied to one of the two identical electrodes, which are lowered into the well under the same conditions, giving specific electromotive forces upon the chemical action of these peai eHTOBs on oil, gases, Boda and rocks, in which a well is drilled. The change in the potential difference between both elektrodrody, depending on what (oil, gas, rock, etc.) comes into contact with the reagent during the passage of squalls. gives an indication of the presence of oil, gas, water, or those or other rocks in this area of wells 1.
