1.high-pressure mud driven down hole drill 2.details according to the request 3.many types
Screw drill is a highpressure mud driven.drives downhole drilling tool rotation. with a simple operation .low cost. and other prominent advantages.which can be used for vertical wells. directional wells and horizontal well drilling and workover operations.
Company's existing screw drill specifications:5LZ172x7.0HS-5,7LZ172x7.0HS-5,5LZ197x7.0HS-5,5LZ197x7.0HS-6,7LZ197x7.0HS-5,5LZ203x7.0HS-5,5LZ216x7.0HS-5,5LZ228x7.0HS-5,5LZ244x7.0HS-5.Products are used in the Shengli Oilfield, Changqing Oil Field and other major oil fields. Product performances reach the domestic advanced level.
Directional screw drill produced by the company is designed and manufactured for the horizontal drilling with a bent housing and a new stabilizer screw drill.with PDC or roller cone drill bit different BHA components for directional drilling Series.complete replacement of manufacturing ramp and BHA not achieved steady ramp section and the horizontal well drilling operations.It has the following characters.
Shell with different shaft diameters and different shapes of the stabilizer. the user can choose according to the drilling process requirements .
Cardan shaft housing with a single bend and double bend bend in two forms. and have different perspectives on the corner for users to choose.choose double-curved shell with two-to two-bend and reverse bend. Conventional drill corner and made the slope (see table below) for reference
Shunt motor rotor designs a center hole. the entrance is equipped with nozzle. which can increase the input flow, high-pressure jet drilling, horizontal drilling to solve difficult problems carrying debris on the back. When need the smaller displacement, it can block the rotor holes.
According to user's requirements, select the number of rotor and stator during the first few head ratio 5:6,7:8,9:10 other specifications. and can provide with the pressure reduced to 14MPa water hole drilling products according to users' requirements.
