FIELD: oil and gas industry.
SUBSTANCE: invention relates to evaluation procedure of oil and gas subterranean structure field. Test of rupture by discharge/release consists of charging of fluid, gas or its combination, containing desirable additions for compatibility with structure, at discharge pressure, exceeding structure rupture pressure, with following stopping period. Pressure decay during the stopping period is measured and analysed for the detection of penetrability and resistance of rupture face by means of preparation of specialised Cartesian diagram on the assumption of stopping data by means of application of corrected pseudovariable, such as data of corrected pseudopressure and data of corrected pseudotime. This analysis provides for data on diagram to be places lengthwise straight line along with constants or depending of pressure properties of fluid. Incline and intersection of straight line are correspondingly indicators of penetrability calculation and rupture face resistance R0.
EFFECT: reduction of harmful effects influence of depending from the pressure fluids properties at penetrability calculation and rupture face resistance of tank.
