Abstract
A device to affect oil-saturated layers and bottom hole zone of horizontal wells includes an emitter, a housing, presenting a double-moduled configuration, wherein the a first module and a second module are interconnected. The device includes a condenser charging unit of the first module, which is connected to an equipment that is located at a wellhead and has the capacity to transmit the data and condenser charges using a delivery tool, and a sensor that controls the force arising at the junction of the delivery tool and the device.
Claims2
A method of affecting an oil-saturated formation and a bottom hole zone of a horizontal well, said method comprising the steps of:
- immersing a device capable of explosive plasma formation into a wellbore in order to generate pulses,
- immersing the device sequentially first in a vertical part of the wellbore, and then, with a delivery means, to a 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 the pulse generating device are controlled simultaneously as well as the location of the device with respect to the longitudinal axis of the borehole using a 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.
A device to affect oil-saturated layers and bottom hole zone of horizontal wells, said device comprising:
- an emitter;
- a housing, presenting a double-moduled configuration, wherein a first module and a second module are interconnected
- a condenser charging unit of said first module, is connected to an equipment that is located at a wellhead and has the capacity to transmit data and condenser charges using a delivery means, and a sensor that controls the force arising at the junction of said delivery means and said device, wherein in said second module, a condenser charging unit of said second module, the emitter, and a supply unit of active substance are interconnected, wherein a centralizer is located on a housing of said second module after said supply unit of active substance to ensure alignment of the longitudinal axis of said device and the longitudinal axis of a borehole.
