摘要： The present invention relates to tools and methods for stabilizing incompetent or otherwise unstable subterranean zones or formations penetrated by a well bore during drilling. The methods basically comprise drilling the well bore through an unstable subterranean zone or formation when it is encountered, pumping a fluid through a well stabilization tool while moving the tool through the portion of the well bore in the unstable zone or formation whereby fluid jets formed by the well stabilization tool enlarge the diameter of the well bore by fluid jet erosion, pumping a hardenable cementitious material through the well stabilization tool while moving the tool through the enlarged portion of the well bore whereby the enlarged portion is filled with the hardenable cementitious material, allowing the cementitious material to harden and then drilling the well bore through the hardened cementitious material.

摘要： A drill stem diverter tool for removing gelled drilling fluid and filter cake from the side of a well bore. The apparatus comprises a housing adapted to be connected into a drill string. The housing includes a plurality of diverter ports which communicate a central opening of the housing with a well annulus. A valve means which can be moved from a first position which blocks the diverter ports to a second position which opens the diverter ports is disposed in the central opening. The diverter ports are angled and offset from the center line of the housing so that the fluid exiting the ports creates a turbulent circular motion. A stop is provided to limit the movement of the valve means. The valve means may also be moved from its second position back to its first position to block communication to the well annulus through the diverter ports.

摘要： Improved methods and apparatus for placing and cementing a casing string in a horizontal well bore section are provided. A float shoe is attached to the end of the casing string and a float collar is connected in the casing string for trapping air in a first portion of the casing string thereby causing it to be buoyed up during placement by drilling fluid contained in the well bore. A selectively openable and releasable closed baffle assembly is connected within the casing string for trapping air or a low density fluid in a second portion of the casing string thereby causing it to also be buoyed up by drilling fluid in the well bore. The buoying up of the casing string reduces placement drag and consequent compressive loading on the casing string. After placement, the closed baffle means is opened to allow fluid circulation and conditioning of the annulus. A bottom cementing plug is then landed on the baffle assembly and the baffle assembly is released and moved to the float collar. A cement slurry is thereafter placed in the annulus and allowed to set therein.

摘要： The present invention is directed to an apparatus and method for reverse circulation cementing a casing in an open-hole wellbore. The apparatus includes a surface pack-off device, which has a housing defined by an upper section and lower section. A load bearing plate is secured to the housing between the upper and lower sections. The load plate and lower section of the housing cooperate to prevent sloughing of the earth at the surface of the wellbore via a section of casing string. The surface pack-off device also includes a casing hanger, which couples to the casing in the wellbore. Fluid inlets allow the cement to be pumped into the wellbore in the annulus formed between the casing and wellbore sidewall. The method includes the steps of installing the surface pack-off device and operation on reverse circulation of the cement down the annulus.

摘要： An embodiment of a downhole tool for use with a workstring in a wellbore includes a first section, a second section, and a coupling mechanism adapted such that in a first configuration the coupling mechanism couples the first section to the second section. In a second configuration, the coupling mechanism does not couple the first section to the second section. Also disclosed is a method for creating a plug in a wellbore, the method comprising: injecting a slurry into the workstring to form a plug in the wellbore, positioning a flow preventing mechanism into the workstring to prevent fluid flow from exiting the workstring, inducing a coupling mechanism to uncouple a portion of the workstring such that the portion remains with the slurry to create the plug in the wellbore, and removing the first section from the wellbore.
