(54) СПОСОБ ПРИГОТОВЛЕНИЯ БУРОВОГО РАСТВОРА И УСТРОЙСТВО ДЛЯ ЕГО ОСУЩЕСТВЛЕНИЯ(54) METHOD FOR PREPARING A DRILLING SOLUTION AND DEVICE FOR ITS IMPLEMENTATION
Изобретение относитс к приготовлению бурового раствора и может быть применено в нефтегазодобывающей промышленности при бурении скв.ажин, а также в строительной, химической и других отрасл х народного хоз йства.The invention relates to the preparation of drilling mud and can be applied in the oil and gas industry when drilling wells, as well as in construction, chemical and other sectors of the national economy.
Успешна проводка скважин с мини- мальными экономическими затратами и высокими скорост ми бурени в значительной степени зависит от качества буровых растворов, от степени их диспергации . Принудительное диспергирование твердой фазы бурового раствора позвол ет сократить расход глиноматериалов за счет повышени выхода бурового раствора из 1 т глинопорошка. Диспергирование твердой фазы вл етс процессом принудительного измельчени частиц до коллоидальной величины . Коллоидальные глинистые частищл вл ютс основной составл ющей дл образовани структуры бурового раствора . Диспергирование твердой фазы в жидкой сопровождаетс физико-химическими изменени ми, вли ющими на состо ние и свойства как твердой, так и жидкой фаз.Successful drilling of wells with minimal economic costs and high drilling rates largely depends on the quality of drilling fluids and on the degree of their dispersion. The forced dispersion of the solid phase of the drilling fluid makes it possible to reduce the consumption of clay materials by increasing the yield of drilling mud from 1 ton of mud powder. Dispersing the solid phase is the process of forcing particles to a colloidal size. Colloidal clay particles are the main component for forming the structure of the drilling fluid. The dispersion of the solid phase in the liquid is accompanied by physicochemical changes that affect the state and properties of both the solid and liquid phases.
Известны способы приготовлени бурового раствора путем смешивани твердой и жидкой фаз и последующегоMethods are known for preparing a drilling fluid by mixing solid and liquid phases and subsequent
диспергировани твердой фазы с приме нением механических, механогидравлических , гидродинамических воздействий . Такие способы позвол ют осуществл ть измельчение твердой и смешивание ее с жидкой фазой с достаточной степенью гомогенизации {i.dispersion of the solid phase with the use of mechanical, mechanohydraulic, hydrodynamic effects. Such methods allow grinding the solid and mixing it with the liquid phase with a sufficient degree of homogenization {i.
Однако при измельчении полидисперсных порошкообразных материалов таки- , However, when grinding polydisperse powdered materials such-,
10 ми способами не удаетс измельчить все частицы до одного размера за один цикл, в результате чего исходную суспензию приходитс многократно пропускать через активную зону диспергиру15 ющего воздействи .It is not possible to crush all the particles to the same size in one cycle using 10 methods, as a result of which the initial suspension must be repeatedly passed through the active zone of the dispersing effect.
Известен способ приготовлени бурового раствора путем диспергировани твердой фазы в воде в многоступенчатом диспергаторе 2 .There is a known method of preparing a drilling fluid by dispersing a solid phase in water in a multistage disperser 2.
2020
Необходимость разбавлени бурового раствора водой по известному способу вызвана тем, что при диспергировании твердой фазы количество частиц и активна поверхность их резко возраста.ют и вода пе)еходит из свободного состо ни в св занное дл образовани гидратных оболочек, что резко снижает в зкость раствора.The necessity of diluting the drilling fluid with water according to a known method is due to the fact that when the solid phase is dispersed, the particles and the active surface age rapidly and the water does not flow from the free state to the bound to form hydration shells, which drastically reduces the viscosity of the solution.
