WELL CALIBRATION METHOD ALONG BOREHOLE ELONGATION IN REGARD TO ITS VERTICAL COMPONENT Russian patent published in 2015 - IPC E21B47/00 

Abstract RU 2559967 C1

FIELD: oil and gas industry.

SUBSTANCE: invention claims well calibration method along borehole elongation in regard to its vertical component, which consists in determination of height for hydrostatic fluid column against its pressure at the lowest point. At that the well with casing is closed by a packer over the productive formation or at the required depth, filled with fresh or mineralised water of known density, water level is kept unchangeable at the well mouth, pressure and temperature is measured in the well at equal gaps of length of the run down cable or wire with downhole pressure and temperature range. Borehole elongation from its vertical component is defined according to the mathematical expression specified below.

EFFECT: improved accuracy for determination of curvature degree and elongation of the well borehole.
