| Abstract: | The influence of borehole temperatuer, drill cuttings, surge pressure and annular pressure drop on the effective static bottomhole pressure of drilling fluid is analyzed in this paper. Their calculation formulas are introduced during drilling and tripping operations is discussed, and its calculation formulas are derived. The calculation program used for PC-1500 computer is also compiled. |
