摘要： The invention relates to a method and to a tool for treating at least one wall in a critical zone of a borehole, in particular a borehole for development of a hydrocarbon, water, gas or analogous field, the method consisting in reinforcing the wall of the critical zone by a coating obtained from a base fluid which is pumped from the surface to a tool (1) to be projected against the wall of the critical zone where it forms the coating once it has set, the method being characterized in that it consists in storing at least one additive or activator in liquid form in a reservoir (R) of the tool (1), and in projecting the additive simultaneously with the base fluid against the wall of the critical zone via at least one injector (I) in order to activate setting of the base fluid.

摘要： A fiber optic pressure transducer having enhanced resolution and dynamic range includes a fiber optic core having one or more gratings written onto it, a birefringence structure for enhancing the birefringence of the core, and a structure for converting isotropic pressure forces to anisotropic forces on the fiber core. Several different embodiments of prestressing structure are disclosed (both extrinsic and intrinsic). Several different embodiments of structure (both extrinsic and intrinsic) for converting isotropi c pressure to anisotropic pressure are also disclosed. The fiber optic pressure transducer according to the invention is advantageously used in conjunction with a light source and a spectral demodulation system in order to detect pressure ambient to the fiber optic pressure transducer based on the wavelength and shift of spectral peaks.

摘要： A method of cementing a well permitting a reduction in the degree of diameter reduction of casing or liners required, and not requiring excessively large initial conductor casing, is described. The method is characterized by provision of an enlarged wellbore and a novel liner structure which is adapted for expansion of a reduced diameter section thereof downhole, providing, before expansion of the section, unimpeded flow of fluid from the enlarged wellbore during cementing and close fit of the expanded section with the casing or preceding liner, after cementing is completed and expansion of the section. A novel well liner structure and novel well liner expansion means are disclosed.

摘要： A borehole tool analyzes formation gas composition. It includes an optical fluid analyzer (OFA) and a gas analysis module (GAM). The OFA determines when fluid flowing into the tool is gas, which is diverted to the GAM, avoiding oil deposits on optical windows which interfere with the analysis. The GAM includes a near infrared ray light source, photodetector(s), gas sample cell(s) having portions with optical windows and different path lengths, and fiber optics directing light to the sample cell, and from the sample cell to the photodetector(s). Cells with different path lengths increase dynamic range. The GAM includes optical paths directly from the light source to the photodetector(s) (canceling drift), and from the light source through a standard such as methane to the photodetector(s) (compensating shifts in hydrocarbon peak locations or optical filter wavelengths). Analysis is based on selected CH vibrational peaks in the 5700 cm-1 to 6100 cm-1 range.

摘要： This invention relates to a wellbore fluid comprising a liquid dispersion of a particulate mixed divalent metal carbonate which has a generally platey crystal form, like a mixed alkaline earth metal carbonate. The present invention relates also to a method of well construction, well remediation or stimulation wherein a wellbore fluid, comprising a liquid dispersion of a particulate mixed divalent metal carbonate which has a generally platey crystal form, is employed.

摘要： A releasable connection between the lower end of a running string and a well tool that is subject to being stuck in a well includes inner and outer members movable telescopically between contracted and extended positions, a tension sleeve connecting the members in the contracted position and being disrupted by a predetermined pull to allow telescoping movement, a stop nut to limit such movement in the extended position of the members, and a mechanism responsive to a certain number of cycles of telescoping movement for disabling the stop nut to allow complete release and separation of the members.

摘要： The flow meter comprises a tube (4) that vibrates under drive from a generator (7) with the displacements of the tube being measured by two sensors (8 and 9) producing signals that are phase-shifted by the Coriolis force acting on the fluid flowing along the tube (4), in a manner that is indicative of its mass flow rate. The originality of the invention consists in a jacket (5) surrounding the tube (4) and in which a fluid (6) is contained and is kept automatically at the same pressure as the flow. This makes it possible to use tubes (4) that are thin and flexible even with flows that are at high pressure.

摘要： A method is provided for controlling the delay time of aqueous borate-crosslinked polysaccharide-based fluids for hydraulic fracturing and related applications which allows on-the-fly control of the delay time without comprising overall fluid integrity. Without having to modify the total boron content nor pH of the fracturing fluid, the delay time is controlled by adding a polyol to the fracturing fluid at a first rate, determining the resulting delay time and then adjusting the rate of the polyol addition to the fracturing fluid until the desired delay time is achieved
