The main technical problem of horizontal well workover are: large friction, easily lead to weight indicator distortion, tension and torque is not easy to transfer to the sticking point; due to the well string is close to the wall, a long "sand bed" section is easily to form at washover and sand flushing; in fishing, fish guidance (or fish withdrawal) is more difficult.
With a supporting 18° slope sectional rod of 7,000 meters, dedicated elevator, axial rolling slider and other horizontal wells workover tools, we are capable of Horizontal Interval stuck unfreezing, fishing, casing milling and other workover.
