A METHOD FOR APPLYING PHYSICAL FIELDS OF AN APPARATUS IN THE HORIZONTAL END OF AN INCLINED WELL TO PRODUCTIVE HYDROCARBON BEDS

摘要

The invention relates to the field of oil and gas industry for stimulation of oil production. The method includes delivering and placing in a horizontal wellbore of a device equipped with electricity accumulating unit, a transmitting source having two electrodes, which are circuit closed by the operator's command with a calibrated metal wire, causing it to explode and form a high pressure targeted shockwave spread radially from given points of the horizontal wellbore in order to increase the permeability of a bottom hole zone of a working sections of the horizontal wellbore. The invention provides for the most effective and environmentally safe exploitation of inclined horizontal wells.

1. A method of affecting an oil-saturated formation and a bottom hole zone of a horizontal well, said method comprising the steps of:
immersing of a device capable of explosive plasma formation into a wellbore in order to generate pulses, immersing the device sequentially first in the vertical part of the wellbore, and then, with the delivery means, to the horizontal part, configuring the delivery means to transmit the necessary force to move the device along the horizontal part of the wellbore; whereas, when the pulse generating device is immersed in the horizontal direction, the force at the junction of delivery means; and generating pulses device are controlled simultaneously as well as the location of the device with respect to the longitudinal axis of the borehole using centralizer, after the device has reached its target point, it is activated to form a series of successive vibrations radially propagated from the well inward the formation.
