| Abstract: | I38H is a prior drainage horizontal well in adjustment wells of Bohai oilfield, which was used for injection in later stage. 827.0m horizontal section was designed to satisfy injection-production relation of 3 wells in the surrounding. I38H is also a shallow displacement well with horizontal and vertical ratio of 2.47. For the safety of drilling operation, by the optimization of hole configuration, rational design of wellbore trajectory, the use of beck rotary steering tool and the reamer while drilling, well I38H drilling operation was successfully comleted. |
