The continuous whipstock is a whipstock tool that can continuously bend the borehole after being oriented in the hole. A wedge is provided, and a certain lateral force is generated by a special mechanism to achieve directional deflection.

It can save many times of tripping and tripping of drilling tools and directional operation time; and can make holes with the same diameter, and the hole body is a smooth curve; it can use drilling parameters that are not much different from conventional drilling, without adding special equipment. The continuous whipstock is generally used to build the wall at the bottom of the hole; it can also directly build the branch hole at the bottom of the artificial hole created by the quick-setting slurry. It is suitable for medium-hard and hard complete formations of grades 5-9, and the deflection strength can reach 0.5. ~2. /Meter. The structure of the continuous whipstock includes two parts: guide and whipstock. According to the different positioning methods, there are continuous whipstocks such as slider positioning type, support block clamping type, and deflection positioning sleeve type. The LZ type continuous whipstock developed by the Institute of Prospecting Technology of the Ministry of Geology and Mines of China belongs to the slider type.
