METHOD FOR PRE-EVALUATION OF VALUE OF ABNORMALLY HIGH STRATAL PRESSURES IN OIL-AND-GAS BASINS

摘要

Method for preliminary evaluation of value of abnormally high stratal pressures in oil-and-gas bearing basins includes estimation of excess pressure, defined values of initial stratal pressure, gradient of initial stratal pressure, height or distance from point of measurement to point of determination of excess pressure, determination of depth of bedding of screening thickness of catagenetic impermeable bed, determination of depth of bedding of isothermal surfaces 110 DEGREE C and 120 DEGREE C and crystalline basement, determination of predicted value of abnormally high stratal pressure.
