Deflecting tools produced by our company include ground anchor type whip stock and hydraulic setting slip type whip stock. Hydraulic setting slip type whip stock is provided with accurate direction, solid setting and other characteristics.
When reservoir casing is seriously damaged or reservoir is collapsed and buried by sands so that oil wells cannot produce oils, to use the upper casings and reduce costs of drilling ahead, window sidetracking can be made on the upper casing on the top of the reservoir to for new boreholes for oil production.
Window sidetracking in the casing is an important means to drill a deviated well in a well with the lower casings seriously damaged so as to make the well restore production capacity.
Window sidetracking tools mainly include whip stock and window milling taper.
