摘要： A rotary drill bit for use in drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, a number of blades formed on the leading face of the bit and extending outwardly away from the axis of the bit so as to define between the blades a number of fluid channels leading towards the gauge region, a number of cutting elements mounted side-by-side along each blade, and a number of nozzles in the bit body for supplying drilling fluid to the fluid channels for cleaning and cooling the cutting elements. In each of the fluid channels, adjacent the gauge region, is an opening into an enclosed passage which passes internally through the bit body to an outlet which, in use, communicates with the annulus between the drill string and the wall of the borehole being drilled. The gauge region of the drill bit comprises a substantially continuous bearing surface which extends around the whole of the gauge region.

摘要： A choke device for controlling fluid flow, particularly in a modulated bias unit, drill bit or other item downhole drilling component, comprises a passage for the flow of fluid, a choke aperture separating an upstream portion of the passage from a downstream portion thereof, and an impingement surface located in the downstream portion of the passage opposite and spaced from the choke aperture, so that fluid flowing through the choke aperture impinges on the impingement surface. The impingement surface is formed from superhard material, such as polycrystalline diamond, and may comprise the front facing table of a two-layer polycrystalline diamond compact of the kind used as cutting elements in drag-type drill bits.

摘要： A rotary drill bit for drilling holes in subsurface formations comprises a bit body having a leading face and a gauge region, and a plurality of blades formed on the leading face of the bit body and extending outwardly away from the axis of the bit towards the gauge region so as to define a fluid flow channel between the leading edge of each blade and the trailing edge of the adjacent preceding blade. A plurality of cutting elements are mounted along the leading edge of each blade, and there is provided, in one or more of the channels, a main nozzle which directs fluid along the leading edge of one blade so as to clean and cool the cutting elements on it, and a subsidiary nozzle which is located and orientated so as to direct fluid along the trailing edge of the preceding blade in a direction opposite to the direction of flow from the main nozzle, so as to tend to enhance partial recirculation of fluid flow in the flow channel between the blades.

摘要： A computer system programmed to process a large data set includes means for analysing the data set. The means for analysing the data set typically comprises a means for finite element analysis. The computer system also includes means for applying a data compression technique to the analysed data set such that the compressed analysed data set has high fidelity in regions of interest and has lower fidelity in regions of lesser interest. The data compression technique comprises the use of a wavelet compression technique. The computer system comprises a high specification server and a local workstation. This compressed analysed data set is easily managed by the local workstation to produce different cross-sectional displays without reusing the high capability server. The analysed data set for example comprises a 4D data set of a fan blade containment analysis of a casing.

摘要： A stimulation technique is provided for use in an open hole well. The stimulation technique utilizes a system which comprises one or more isolation devices positioned to isolate desired regions of the open hole well. At least one release mechanism is used to provide controlled release of stimulation material to a desired wellbore region of the open hole well. Additionally, a protection mechanism cooperates with each release mechanism to prevent undesirable contact between stimulation material and the surrounding wellbore wall of the open hole well. In many applications, the entire system is deployed and operated during a single trip downhole into the well.

摘要： The present invention discloses a system using a conduit run into a well on a service string. In one embodiment the conduit includes outlets along its length to permit a sand control treatment to exit the conduit along the length of the conduit and distribute the sand control treatment along the length of the conduit. The conduit can have a plurality of such outlets spaced to provide an even distribution of the sand control treatment. The conduit can be attached to the delivery tubing (such as coiled tubing or service string tubing) via a releasable connector. The conduit is deployed on the delivery tubing and connector (and is in fluid communication therewith) in the well adjacent to an area to be treated. The sand control treatment is pumped into the well. Once the sand control treatment is complete, the releasable connector is released to disconnect the conduit from the delivery tubing and the delivery tubing is removed from the well.

摘要： A technique facilitates sand control in a wellbore. A lower completion and an upper completion are run downhole into the wellbore and deployed. The lower completion assembly employs a plurality of packers to isolate well zones. The lower completion assembly also has gravel pack ports which are independently opened to enable gravel packing of each individual zone via a tool run downhole. Additionally, the lower completion assembly has a production port in each zone. A shifting tool is employed to open the production ports and to enable production from the well zones.
