       On January 10, the first domestic rig cross-sliding device developed by Baoji Petroleum Machinery Co., Ltd. successfully completed a full-unit sliding test under a loaded counterweight and a bearing load of over 700 tons.

  During operation, the sliding device uses hydraulic cylinders to push the entire rig so that it can slide in all directions, with a maximum moving speed of up to 40 centimeters per minute. Where ground conditions permit, construction personnel can carry out large-range relocation operations according to well locations. During movement, if significant deviation occurs, compensation valves can be used for dynamic adjustment to ensure that all modules move synchronously and smoothly.

  This sliding device can be used for cluster well operations with large rigs of over 5,000 meters. Compared with the previous translation method using pawls, it is simpler and faster, can greatly reduce the frequency and cost of rig moves, and has broad market prospects and good economic benefits. Only two companies worldwide can produce this type of sliding device. At present, Baoji Machinery has received orders for three sets of the device.
