METHOD FOR MEASUREMENT OF UNSTEADY-STATE PRESSURE IN TESTING OF OIL-GAS-CONDENSATE- AND WATER-BEARING FORMATIONS Russian patent published in 1994 - IPC

Abstract RU 2012794 C1

FIELD: development and operation of liquid mineral fields. SUBSTANCE: method includes filling of well with fluid. Run into well is sensitive element of instrument in form of specially graduated member of reactive electric load with distributed parameter depending on medium dielectric permeability over well axes. Subject to determination are angle of inclination of well axis to vertical in point of instrument location, density and dielectric permittivity of medium. Variation of integral value of parameter of reactive load is registered. Value of unsteady-state pressure is determined by calibrated nomograph. EFFECT: higher efficiency. 1 dwg
