tool for drilling horizontal wells and слабонаклонных шнекового

摘要

the utility model relates to a mining industry, namely to instrument for шнекового and слабонаклонных drilling horizontal wells.the tool is in the form of a two-step расширителя consisting of забурника, двухлучевого corps first stage with the cutting tool and скалывающими rollers.as well as the effect on the first stage of winding the spiral spring.the second step includes the hull, offsite weights, two двухзаходные platform augers screw blade with metal scrubbed - чистителями.;the technical result affirmed useful model is to improve the direction of drilling horizontal wells and слабонаклонных by providing the conditions for equality of capacityfor the counter rotation of двухступенчатых расширителя and improve treatment of products of призабойного space двухлучевого corps second access yeni расширителя.;orientation of drilling is achieved because of the first and second steps расширителя кинематически linked through the conical двухпоточный radial planetary red ктор,an inside of the second level.these are counter rotated relative to each other, forming conditions of equality as capacity required to rotate the first and second steps расширителя.;improved cleaning призабойной zone wells is that межлучевом space the second step to its body rigidly attached двухзаходные platform augers лопаст screw and.in this for not транспортирующими surfaces шнековых screw blades rigidly mounted metal brushes - чистители. 2 z. s - lu, 3).
