| Abstract: | The paper presents three mathematical models to describe the kick process by establishing differential equations, namely linear function, non-linear function and special non-linear function, and compares their graphs with each other. These equations provide theoretical bases for determining coefficients of predicting formation pore pressures. According to this, a novel method of predicting formation pressures is brought forward. Additionally, the calculating formulas and samples are also introduced in this paper. |
