Mechanical continuous whipstock is one of the directional drilling techniques. Nowadays, single-slider and hole wall support are used for commonly-used LZ continuous whipstock with small radial braking torque, the angular displacement is easy to occur in the whipstocking process, which affects the whipstocking effect, and the slanting angle adjustment is not easy to operate. In order to solve the slanting stability, a new type of double-slider continuous whipstock is specially designed and developed, which is stably clamped and the slanting angle can be adjusted, the device reliability is verified by field test. The innovative features of this new continuous whipstock are: (1) double-slider structure, there is no precedent in China, has been approved utility model patent; (2) The slanting adjustment mechanism is added, which can be adjusted according to the construction requirements; (3) The upper slider is returned back by means of the threaded connection between the work spring and the upper slider assembly; (4) the lateral force of the upper slider is controlled by a pressure-division joint, which reduces the slanting drilling resistance when the clamping requirements are met. This new type of double-slider continuous whipstock is the initiate both in China and abroad with independent intellectual property rights, which has good application effect and good prospects of development and popularization.
