| Abstract: | Well No. 7-Ping 1 in Gudong Oilfield is the first offshore well produced onshore, the oil production of which is 6 times more than conventional vertical wells. Designed and drilled by Shengli Oilfield, the well is characterized by the complicated casing program and formation pressure, the greatest three-dimensional bending deflection and the most accurate horizontal displacement. The paper presents the well design criterion and drilling procedures, and summerizes the well path control technique and the major drilling accomplishments. |
