Apparatus and method to remotely control fluid flow in tubular strings and wellbore annulus

摘要

A method and apparatus is disclosed for remotely and selectively controlling fluid flow through tubular string disposed within a wellbore and further control fluid flow between the tubular string inner flow passage and the annular flow passage. The present invention further discloses a method of selectively and remotely receiving and interpreting a form of command or information at a desired apparatus within the wellbore caused by the operator on earth surface.

主权项

1. An apparatus for remotely controlling fluid flow in a wellbore based on changing the environment in the wellbore, the apparatus disposed on a tubular string in the wellbore, the apparatus comprising:
a body, an inner passage through the body, an orifice to the inner passage disposed on a lateral side of the body, a valve having a movable element, the valve disposed in fluid communication with the inner passage and the orifice, a means for actuating the valve element, a means for powering the means for actuating the valve element, a means for disabling movement of the valve element, a means for detecting at least one change in the environment in the wellbore, a means for decoding the at least one change in the environment, and wherein the means for disabling movement of the valve element is responsive to the means for decoding, and wherein the means for actuating the valve element is responsive to the means for decoding, and wherein the at least one change in the environment includes a mechanical movement of the apparatus by means of moving the tubular string, causing the apparatus to move within the wellbore in at least one direction.
