Title:
METHOD FOR INCREASING THE PENETRABILITY OF THE BOTTOM-HOLE AREA OF AN OIL-BEARING FORMATION
Document Type and Number:
WIPO Patent Application WO/2004/001187
Kind Code:
A1
Abstract:
The invention relates to the oil-and-gas industry. The aim of said invention is to efficiently increase the penetrability of the bottom-hole area of an oil-bearing formation and to reduce energy consumption by improving the accuracy of measurement of parameters of pulsed electric processing. The inventive method for increasing the penetrability of the bottom-hole area of an oil-bearing formation consists in determining the porometric curve of collector material in the bottom-hole area f (r) during the measurement of geophysical parameters. Said porometric curve is used for calculating a mean value of the radius rmean of pore channels. Afterwards, a pulse length $g(t) and a minimum permissible current density corresponding thereto are determined. Relative pulse duration is set within a range of 1-3 and the time of the pulse processing is selected according to a corresponding formula.
