It is a kind of high-efficient casing window opening tool which is consisted of whipstock,hinge adaptor, hydraulic control system, anchoring system, pack off ng shoe assembly. With special structure of hydraulic system, it can be applied widely for window opening in vertical well, directional well and even horizontal well. Its hydraulic anchoring system has very high safe reliability.Features1. Design two rows of anchoring slips to ensure the whipstock set in the casing steadily and stably.2. Apply 2-3 degrees ramp to make a relatively small dogleg degree at the window and ensure the drilling string pass through the window exit smoothly.3. Optimal designed milling shoe assembly (including lead mill and dress mill) can achieve high milling speed, low milling torque and smooth window quality.4. Orient with MWD or UBHO/GYRO available.5. Only one trip to set whipstock, mill casing exit and drill rat hole.6. Hydraulic system is retrievable.
