FIELD: oil and gas industry.SUBSTANCE: within the whole period of the well survey the borehole pressure determination method includes measurement of temperature at least at one point during the whole period of the well survey, definition of non-standard temperature profiles along the borehole during the whole period of the well survey, calculation of density change in the well fluid and measurement of tubing string length in the shut-in well and correction of measurement results of borehole pressure based on calculated change in the well fluid density and tubing string length.EFFECT: improved accuracy of borehole pressure determination.5 cl, 6 dwg |
