摘要： A simple debris removal apparatus for use in a wellbore. In one aspect of the invention a modular, interchangeable venturi is provided which can be retrofit into an existing debris bailer having a filter and a debris collection container. In another aspect of the invention, a venturi is utilized to create a negative pressure in a wellbore sufficient to actuate a retrieval tool for a downhole device. In yet another aspect of the invention, a combination tool is provided which can evacuate debris in a wellbore, thereby uncovering a downhole device which can then be removed in a single trip. In yet another aspect of the invention, a debris removal apparatus is provided with a method for utilizing the apparatus in a wellbore on coiled tubing.

摘要： A downhole differential flow control valve is provided that utilizes a differential pressure area having one pressure area on which the wellbore pressure acts and a second area different from the first area on which pressure in the tubing acts. The differential area reduces the load in which the spring is required to exert a closing force in the valve. Thus, a coil spring can be used to improve the closing speeds of the valve.

摘要： Methods and apparatus enable expanding tubing in a borehole of a hydrocarbon well. According to some embodiments, an expander device includes a collapsible swage formed of collets, at least one slip arrangement and a hydraulic jack to stroke the swage through tubing to be expanded. In operation, expanding tubing may include securing an expansion tool to the tubing, lowering the tool and tubing into a borehole, actuating a collapsible expander of the expansion tool to an extended configuration, and supplying fluid pressure to a jack coupled to the expander thereby moving the expander through the tubing which is held by at least one of first and second tubing holding devices disposed respectively ahead of the expander and behind the expander.

摘要： The present invention provides a downhole cementing apparatus run into a borehole on a tubular. The apparatus is constructed on the pipe in such a way that pressure surge during run-in is reduced by allowing fluid to enter the pipe and utilize the fluid pathway of the cement. In one aspect of the invention, an inner member is provided that filters fluid as it enters the fluid pathway. In another aspect of the invention, various methods are provided within the cementing apparatus to loosen and displace sediment in the borehole prior to cementing.
