Description

Известны водоподъемные устройства бурового шнекового |:нар да, содержащие гравийко-сетчатый фильтр с чехлом, помещенным между буровыми ннстру.ментами и бурильными трубами, и покрываемым раствор ющейс  в воде защитной массой, предохран ющей сетки от разрущени  в процессе бурени - Такие устройства не получили практического применени  вследствие отсутстви  защитной массы оптимального состава , в которой сочетались бы механическа  прочность и рагстворимо ть в воде. Одним из основных недостатков  вл етс  также то, что дл  восстаноЕ ени  защитной массы после пробной откачки фильтр необходимо поднимать на поверхность.Known screw-lifting water-lifting devices are known: backdrops, containing a gravel-mesh filter with a cover placed between drilling tools and drill pipes, and a protective mass to be covered with water that protects the grid from destruction during drilling - such devices did not receive practical application due to the absence of a protective mass of the optimal composition, in which mechanical strength would be combined and soluble in water. One of the main drawbacks is also the fact that in order to restore the protective mass after the test pumping, the filter must be lifted to the surface.

Дл  устранени  этих недостатков в предлагаемом устройстве фильтр помещ.ен внутри подвижного щнекового стакана, приподнимаемого дл  пропуска воды при откачке на высоту рабочей части фильтра.To eliminate these drawbacks in the proposed device, the filter is placed inside a movable screw cup, lifted to allow water to pass through when pumped to the height of the working part of the filter.

На фиг. 1 и 2 изображено водоподъемное устройство при бурении и при откачке воды; на фиг. 3 - в разрезе фильтр с щнековым стака гом.FIG. 1 and 2 show the water-lifting device when drilling and when pumping water; in fig. 3 - in section a filter with shnekovy stack.

Фильтр состоит из внутренней перфорирон анной трубы / с сеткой 2, фильтрующего материала 3 и наружной перфорированной трубы 4. покрытой сеткой 5 и дырчатым чехлом 6. На верхней части наружной перфорированной трубы 4 наглухо посажена муфта 7 со щлиаами 8, по которым при обнажении или закрывании рабочей части фильтра скользит щнековый стакан 9. В нижней части щнексвого стакана .9 устроен сальник 10, скольз щий по наружной поверхности дырчатого чехла 6.The filter consists of an inner perforated pipe / mesh 2, filter material 3 and an outer perforated pipe 4. covered with a mesh 5 and a perforated cover 6. On the upper part of the outer perforated pipe 4, a sleeve 7 with shchliya 8 is seated tightly along which The working part of the filter slides a screw cup 9. At the bottom of the screw cup .9 a gland 10 is arranged, sliding along the outer surface of the perforated cover 6.

В пропессе бурени  фильтр защищен от глинизации отверстий шиековым стаканом 9. При достижении устройством водоносного сло  колонну полых щнеков 11, включа  щнековый стакан 9, приподнимают на высоту обнажени  фильтра и начинают откачку воды. По окончании пробной откачки комплект полых щнеков П, включа  щнекозый стака}: 9, опускают в исходное положение, и процесс бурени  продолжаетс .In the drilling process, the filter is protected from claying of the holes by a ridge cup 9. When the device reaches the aquifer, the column of hollow cheeks 11, including the screw cup 9, is raised to the height of the filter exposure and pumping out of the water begins. At the end of the trial pumping, the set of hollow tongues P, including the auger stack}: 9, is lowered to its original position, and the drilling process continues.
