Abstract
Способ выделения в разрезах скважин коллекторов, насыщенных газогидратами, заключающийся в выполнении в скважинах геофизических исследований, включающих плотностной гамма-гамма-каротаж и нейтронный каротаж, отличающийся тем, что по данным каждого из этих методов раздельно вычисляют коэффициенты пористости пород, затем сравнивают полученные результаты между собой, после чего интервалы скважины, в которых значения коэффициентов пористости, вычисленных по данным плотностного гамма-гамма-каротажа, превышают значения коэффициентов пористости, вычисленные по данным нейтронного каротажа, выделяют как коллектора, насыщенные газогидратами. The method of isolating reservoirs saturated with gas hydrates in well sections, which consists in performing geophysical studies in wells, including density gamma-gamma-ray logging and neutron logging, characterized in that according to the data of each of these methods, the porosity coefficients of the rocks are separately calculated, then the obtained results are compared between by itself, after which the intervals of the well, in which the values of the porosity coefficients calculated according to the density gamma-gamma-ray logging data, exceed the values of the porosity coefficients The velocities calculated from neutron logging data are distinguished as reservoirs saturated with gas hydrates.
