Description
Summary:Well M-1 is one of the three exploration wells that PetroChina played in Madura Island, Indonesia in 2010. The well conditions are complex, and most of the layers are overpressure. The layer pressure coefficient of this construction is 1.5, and the proportion in the wellbore is used. It is a mud of 1.8. In this paper, the construction brief is described, combined with the tool principle and field test, the LPR-N valve is opened and the valve cannot be opened at the end of the test and the solution is proposed.
