Description
Отличие способа очистки забо скважин с применением местной циркул ции заключаетс во встраивании в колонну бурильных труб ниже статического уровн жидкости в скважине, погружного насоса с пневматическим приводом, при помощи которого осуществл ют пр мую промывку забо , а также в применении установленного на бурильных трубах забойного шламоуловител . При применении этого способа используют энергию сжатого воздуха при бурении с продувкой в безводных районах.The difference in the method of cleaning wells with local circulation is to embed drill pipes in the string below the static fluid level in the well, a submersible pump with a pneumatic drive, which directly flushes the bottom holes, and also uses a downhole slime trap installed on the drill pipes. . When using this method, the energy of compressed air is used when drilling and blowing in anhydrous areas.
На чертеже схематически изображено расположение оборудовани при очистке забо скважины предлагаемым способом; стрелками показано движение: Б- сжатого воздуха, В - воды и Г - щлама.The drawing schematically shows the location of the equipment during the bottom hole cleaning by the proposed method; the arrows show the movement: B- compressed air, B - water and D - schlama.
В колонну бурильных труб /, расположенных в скважине 2, встраивают ниже статического уровн А жидкости погружной насос 3 с пневмоприводом . В конце бурильных труб в зоне забо над кольцевой коронкой устанавливают забойный шламоуловитель 4.Into a string of drill pipes / located in well 2, a submersible pump 3 with a pneumatic actuator is inserted below the static level A of the fluid. At the end of the drill pipe in the zone of the slab above the annular crown install downhole sewer 4.
Погружной насос осуществл ет пр мую промывку забо скважины; шлам собираетс шламоуловителем.The submersible pump directly flushes the bottom of the well; the sludge is collected by the sludge trap.
