Изобретение относитс к нефтегазодобьшающей промышленности, а имен но к способам дл изол ции зон поглощени бурового раствора при бурении скважин.The invention relates to the oil and gas industry, and specifically to methods for isolating the mud absorption zones during the drilling of wells.
Известен способ установки профильного перекрывател в скважине, заключающийс в выправлении перекрывател под действием гидравлического давлени путем закачки но внутреннюю его полость жидкости 1.A known method of installing a profile overlap in a well, consisting in straightening the overlap under the action of hydraulic pressure by injecting its internal cavity into the liquid 1.
Недостатком указанного способа вл етс то, что он не позвол ет перекрывать зоны поглощени большой мощности.The disadvantage of this method is that it does not allow to block the absorption zones of high power.
Р1звестен также способ соединени профильных труб, который включает свинчивание секций профильных труб, спуск их в скважину и выпр мление их давлением 2.A method of joining shaped pipes is also known, which involves screwing up sections of shaped pipes, lowering them into a well and straightening them with pressure 2.
Недостатком этого способа вл етс необходимость профилировани свинченных цилиндрических участков, соединений перед спуском секцийThe disadvantage of this method is the need to profile the screwed cylindrical sections, the joints before running the sections.

Это усложн ет установку перекрьшател1 , так как требует дополнительных затрат времени на его спуск в скважину.overlap into the well, requiring the use of special equipment. This complicates the installation of a flapper 1, since it requires additional time for its descent into the well.
Цель изобретени - упрощение процесса установки перекрывател в скважине.The purpose of the invention is to simplify the installation process of a downhole valve.

Поставленна цель достигаетс способом, включающим.свинчивание секций профильных труб, спуск их в скважину и выправление внутренним гидравлическим давлением, цилиндриts ческие концы секций перекрывател перед свинчиванием осаживают до диаметра описанной окружности профильной части и после выправлени перекрывател участки соеди 1ени The goal is achieved by a method that includes: screwing the sections of shaped pipes, lowering them into the well and straightening with internal hydraulic pressure, cylindrical ends of the sections of the clapper, before screwing, settle down to the diameter of the circumscribed circumference of the section and
м секций увеличивают до диаметра скважины .m sections increase to the diameter of the well.
На фиг. 1 показаны сви1гченные профильные трубы, спущенные в сква3FIG. 1 shows the curved profile tubes, lowered into the well 3
жниу, на фиг. 2 - профильный перекрыватель , выправленный внутрежнш избыточным давлением; на фиг. 3 сечение А-А на фиг. 1.in FIG. 2 - profile finisher straightened by intravenous overpressure; in fig. 3, section A-A in FIG. one.
Перед спуском перекрывател в скважину концевым участкам каждой его секции 1 и 2 придают цилиндрическую форму. Далее цилиндрические участки на концах секций осаживают до диаметра описанной окружности профильной части. Затем на концах секций нарезают резьбы.Before the shutter is lowered into the well, the end sections of each of its sections 1 and 2 are given a cylindrical shape. Next, the cylindrical sections at the ends of the sections are upset to the diameter of the circumscribed circumference of the core part. Then on the ends of sections cut threads.
Секции свинчивают между собой с применением герметизирующей пасты и спускают в скважину на бурильных трубах, оборудовав нижний конец перекрывател направл ющим башмаком с шаровым клапаном. После спуска перекрывател в интервал установки во внутренней его полости создают (например, цементировочным агрегато избыточное давление, необходимое дл выправлени и плотного прижати профильной части до диаметра скважины . После сбрасывани избыточного давлени производ т отвинчивание бурильных труб от перекрывател и подъем их на поверхность.The sections are screwed together with the use of a sealing paste and lowered into the well on the drill pipe, equipping the lower end of the shutter with a guide shoe with a ball valve. After the shutter is lowered into the installation interval in its internal cavity, (for example, the cementing unit generates excessive pressure to straighten and firmly press the core section to the diameter of the well. After overpressure is released, the drill pipes are unscrewed from the blocks and raised to the surface.
Затем цилиндрические участки соединеИий секций перекрывател увели чивают в диаметре до прижати к стенкам скважины.Then the cylindrical sections of the joints of the sections of the overlap are increased in diameter until they are pressed against the walls of the well.
Применение предлагаемого способа позвол ет производить подготовительные операции по осаживанию цилиндрических концов секций до диаметра описанной окружности профильной части и нарезание на них резьб на базах производственного обслуживани буровых предпри тий или на заводах, что упрощает процесс установки перекрывател в скважине за счет снижени затрат времени на его спуск.The application of the proposed method allows preparatory operations to besiege the cylindrical ends of the sections to the diameter of the circumference of the profile section and thread them onto the production service bases of drilling enterprises or at factories, which simplifies the installation of an overlap in a well by reducing the time required for its descent .
