| titleOfInvention | The method that shale gas reservoir gas-bearing saturation degree is determined by the dipole sonic P-wave And S time difference |
| abstract | The present invention relates to a kind of method for determining shale gas reservoir gas-bearing saturation degree by the dipole sonic P-wave And S time difference, analyzed by core test and obtain shale gas saturation Sg, the dipole sonic that corresponding depth is obtained by same well dipole well-log information indulges shear wave slowness, calculates transverse and longitudinal time difference ratio；It is fitted with the well logging natural gamma of corresponding depth, transverse and longitudinal time difference ratio and shale gas reservoir core test gas saturation, establishes model, determine model coefficient；Natural gamma, the lithology and density logging of well to be explained are obtained by well-log information, total hydrocarbon, the methane content of well gas detection logging to be explained are obtained by gas measuring logging data, landwaste, the rock core lithology of well to be explained are obtained by geological logging data；Divide shale gas reservoir, the gas saturation of the shale gas reservoir of computation partition；Export result of calculation.It is of the invention easy, it is applied widely.The present invention applies 80 mouthfuls of wells in certain shale gas field, and the mean error for calculating determination is no more than 10%, can meet needs. |
