(54) РАСТВОР ДЛЯ ОТМЫВА ПОРОД(54) SOLUTION FOR WASHING BREEDS
1one
Изобретение относитс к физико-химическим методам повышени добычи нефти и может быть использовано в нефтедобывающей промышленности.This invention relates to physicochemical methods for increasing oil production and can be used in the oil industry.
Известна микроэмульси дл отмыва нефти из пластов, содержаша , об. %: углеводород 45-75, алкиларилсульфонат 8-30, содетергент 3-8 и воду О-40 1.The known microemulsion for washing oil from the reservoir, containing, vol. %: hydrocarbon 45-75, alkylarylsulfonate 8-30, detergent 3-8 and water O-40 1.
Основным недостатком такой микроэмульсии вл етс ее высока стоимость.The main disadvantage of such a microemulsion is its high cost.
Известен также раствор дл отмыва пород , содержащий силикат натри и воду 2.A solution for washing rocks containing sodium silicate and water 2 is also known.
Однако известный раствор малоэффективен при отмыве битуминозной нефти из пластов.However, the known solution is ineffective in washing the bituminous oil from the reservoir.
Целью изобретени вл етс повышение коэффициента отмыва битуминозной нефти от пород.The aim of the invention is to increase the ratio of washing the bituminous oil from the rocks.
Дл достижени цели в раствор дополнительно введена канифоль, а компоненты вз ты в следующем соотношении, вес. %:In order to achieve the goal, rosin was additionally introduced into the solution, and the components were taken in the following ratio, wt. %:
Силикат натри 4,,0Sodium silicate 4,, 0
Канифоль0,09-0,2Rosin0.09-0.2
ВодаОстальное.Water the rest.
Канифоль представл ет собой природную смолу - хрупкую стекловидную массу, состо щую в основном из смол ных кислот.Rosin is a natural resin - a fragile vitreous mass consisting mainly of resin acids.
Силикат натри - растворимое в воде соединение кремнезема со щелочью.Sodium silicate is a water-soluble compound of silica with alkali.
Раствор получают при растворении в воде силиката натри или при взаимодействии кремнезема с раствором едкого натри в 5 автоклаве под давлением.The solution is obtained by dissolving sodium silicate in water or by reacting silica with a solution of sodium hydroxide in an autoclave 5 under pressure.
Процесс приготовлени раствора дл отмыва пород состоит в предварительном растворении силиката натри в воде с последующим растворением канифоли.The process of preparing the solution for washing rocks consists in the preliminary dissolution of sodium silicate in water, followed by the dissolution of rosin.
Раствор дл отмыва битуминозной нефти 10 от пород представл ет собой жидкую фазу с удельным весом 1,09-1,12 и в зкостью 1 спз при 20°С.The solution for washing tar oil 10 from rocks is a liquid phase with a specific gravity of 1.09-1.12 and a viscosity of 1 centigrade at 20 ° C.
Эффективность раствора определена путем обработки битуминозной породы гор чим (70-90°С) раствором с последующимThe effectiveness of the solution is determined by treating the bituminous rock with a hot (70-90 ° C) solution followed by
извлечением нефти гор чей водой.extracting oil with hot water.
В качестве примера были приготовлены дев ть смесей ингредиентов:As an example, nine mixtures of ingredients were prepared:
в первом случае, вес. %, силиката натри 5 и канифоли 0,2; 0,1; 0,09, остальное вода;in the first case, weight. % sodium silicate 5 and rosin 0.2; 0.1; 0.09, the rest is water;
во втором случае, вес. %, силиката натри 4,9 и канифоли 0,2; 0,1; 0,09, остальное вода;in the second case, weight. % sodium silicate 4.9 and rosin 0.2; 0.1; 0.09, the rest is water;
в третьем случае, вес. %, силиката натри 4,8 и канифоли 0,2; 0,1; 0,09, остальное вода/in the third case, weight. % sodium silicate 4.8 and rosin 0.2; 0.1; 0.09, the rest is water /
Дл каждой смеси определен коэффициент отмыва нефти, составл ющий 0,85-0,95.For each mixture, an oil washing ratio was determined to be between 0.85-0.95.
