Interpretation of indicator lines of wells with abnormal hydrocarbon properties considering influence of initial gradient and inertial forces

I.R. Hasanov

The paper offers the formulas for definition of initial and the pressure associated with the influence of inertial forces, which is directed against movement and should be additionally overpassed. Analytical view for their definition enabling quantitative evaluation of inertial forces effect on well rate is obtained. The cross-plots of this opposite pressure from depression have been developed. Furthermore, the authors suggest research technique via the method of settled samples, on the basis of which Сi coefficients and р0 initial pressure are calculated; afterwards, upon suggested formula, dependence of pressure (which is directed against fluid movement and associated with the presence of initial gradient and inertial forces) from depression is defined.
