-
Abstract
As an evaluation well, well Bai-70 is the deepest well drilled since the development of Baise Oilfield.Drilling of this well was extremely difficult due to the deep buried depth and large thickness, while the technical requirements were also very high.The technical measures used for safe drilling, sloughing control, stuck pipe prevention and reaming during drilling of this well were described, and field drilling operations showed that these technical measures were effective.The success of this well was significant for the deep well drilling and sloughing control in Baise Oilfield.
