Annotation:
The article briefly enumerates the factors affecting the productivity of oil and gas wells: such as clogging of a formation by drilling fluid and permeability deterioration due to cement slurry filtrate during a casing string cementing.
For the first time, based on the results of gas and oil wells testing, a new mathematical model has been proposed that takes into account the potentially possible, namely, production rate and the initial productivity of the well, above which oil or gas inflow is possible: the increase in the current change of the well production rate is proportional to the productivity that is equal to the difference between the potential (maximum) possible and the current values of the flow rate as well as increases in proportion to the current value of the flow rate, above a certain initial (minimum) amount of oil or gas.
A new method, based on the new calculation formulas but without using known dependencies based on Darcy's law when filtering a liquid (or gas) in a porous medium, for assessing the quality of a formation penetration for oil and gas wells is proposed.
On the basis of the new mathematical model, the results of the study of specific gas wells and the results of experiments performed at GINI and Lomonosov Moscow State University are analyzed in detail under the supervision of academicians L.S. Leibenzon and I.P. Moskalkov. In all cases, a good agreement between the experimental and calculated values was obtained (the error for the predicted estimated flow rates of gas wells does not exceed 3,5...15,0 %, and the error of the calculated values for the experiments of I.P. Moskalkov does not exceed 0,05 %).
