New methods and technologies for designing the processes of construction of wells in complex mining and geological conditions

Authors: V.D. Gorgots (Tyumen Branch of SurgutNIPIneft)
The results of the first developed way of prediction of pore and rocks hydrofracturing pressures around the whole mountain massif section in the open borehole - GOR-PASCAL-FORECAST-1 are shown. The main formulas influencing the stability of the borehole are pointed. The calculations, the conditions of the depth of intermediate casing shoe descent and a new method of calculation - GOR-DEPTH-CASING STRING-1 are given. For an accurate determination of the seam roof with abnormally high formation pressure the first developed high-precision, automated complex of seam roof forecasting - GOR-FORECAST-ROOF-1 is given.
