摘要： A flow meter to be used in a hole drilled in the bedrock for measuring stream flows in bedrock fractures which are transversal to the hole. The flow meter comprises an elongated body having a cross section which is substantially smaller than the diameter of the hole; separating members placed at a distance from each other in the longitudinal direction of the body for separating the examined section from the other parts of the hole in a substantially pressure-tight manner; dividing members for dividing the examined section into two sectors in the longitudinal direction of the hole; and a flow channel extending through the body and equipped with a flow sensor for measuring the direction and rate of the flow between the sectors. In accordance with the invention, the dividing members are formed of thin and elastic sealing strips, which have been fixed to the body and, being substantially perpendicular to the surface of the body, arranged to surround and delimit the sectors.

摘要： In order to increase result accuracy the noise effect during vessel motion is reduced, wherefore direct current pulses are excited the parameters of which are set basing on section conductivity and deposit depth, the electric field is measured simultaneously on pairs of receiving electrodes basing on the spatial averaging of potential of double electric layer that is generated on the boundary of electrode and water during the pulses and pauses between them, and geoelectrical parameters are determined. The device consists of an exciting field generating unit where a switchboard generates pulses on feeding electrodes, a generator consists of two parallel cable lines with emitting electrodes, a non-emitting ballast device that is a pair of alternating electric dipoles with equal moments, and a measuring unit with pairs of sectional receiving electrodes, the total length of an electrode section does not exceed 5% of the distance between the electrodes, and the connection between the electrode elements that are connected to the receiver line through a common input/output provides composition of the EMF that are generated in them.

摘要： Measurements made with a multicomponent logging instrument when used in a substantially horizontal borehole in earth formations are diagnostic of the direction of beds relative to the position of the borehole. When the logging instrument is conveyed on a drilling assembly, the drilling trajectory may be maintained to follow a predetermined trajectory or to maintain a desired distance from a boundary such as an oil-water contact.

摘要： A conductive fluid has been formulated for use in a method of electrically logging subterranean wells. The conductive fluid includes a miscible combination of an oleaginous fluid, a water soluble alcohol, and an electrolytic salt. The electrolytic salt or brine of the salt is present in a concentration sufficient to permit the electrical logging of the subterranean well. The medium may further include gelling agent, weight material, surfactant, or corrosion inhibitors. The oleaginous fluid may preferably be a preferentially-oil-soluble glycol alone or in combination with mineral oil, vegetable oil, synthetic oil, silicone oil or combinations and mixtures of these. The alcohol may preferably be a water soluble glycol or glycol ether such as ethylene glycol, diethylene glycol, propylene glycol and the like. The electrolytic salt or brine may be an inorganic or organic salt, examples of which include sodium chloride, sodium bromide, potassium chloride, ammonium chloride, magnesium chloride, calcium chloride, calcium bromide, sodium acetate, potassium acetate, sodium citrate, or combinations thereof.

摘要： PCT No. PCT/GB95/02047 Sec. 371 Date Feb. 27, 1997 Sec. 102(e) Date Feb. 27, 1997 PCT Filed Aug. 31, 1995 PCT Pub. No. WO96/07090 PCT Pub. Date Mar. 7, 1996A sensor for use in machine wear debris monitoring transducers which detect metallic particles present in a flow of fluid, such as lubricating oil. The sensor comprises an inductive coil having a plurality of turns for surrounding a non-magnetic conduit. An electrically conducting screen is located between the coil and the flow of fluid, the coil being electrically insulated from the screen, so as to isolate capacitatively the contents of the conduit from the coil. The resonant frequency of a tank circuit incorporating the sensor is thus unaffected by changes in the dielectric properties of the contents of the conduit caused by air bubbles and/or water droplets in the flow of fluid. The screen may be a single turn of thin metal foil having a gap between adjacent ends, or a mesh, or a metallic coating sprayed onto the conduit.

摘要： Méthode pour déterminer la teneur des roches sédimentaires en matière organique à partir de données enregistrées dans un puits par au moins deux sondes de diagraphie mesurant des paramètres différents.
Les deux sondes sont choisies l'une pour répondre dans le même sens à une variation de la teneur en eau et en matière organique des roches, l'autre pour répondre de façon très différente à une variation de l'un ou l'autre de ces mêmes constituants et, toutes les deux pour que les lignes I d'iso-teneur en matière organique dans un diagramme à trois pôles, soient sensiblement confondues que le troisième pôle soit le pôle eau P E ou le pôle argile P A . On détermine expérimentalement l'emplacement de la ligne I(0%) et l'on en déduit la teneur en matière organique correspondant à chaque couple de valeurs des paramètres mesurés dans le puits. Dans un diagramme où les paramètres utilisés dépendent, par exemple, du temps de transit ΔT du son dans la roche et de la résistivité électrique R t des formations, les lignes d'iso-teneur constituent une famille de lignes parallèles.
- Application à l'étude des bassins sédimentaires.

摘要： Various disclosed borehole imaging tools and methods provide an improved high-resolution electrode configuration suitable for imaging in both water-based and oil-based muds. In at least some embodiments, the imaging tools employ a unitary conductive body to provide a wall-contacting face with grooves that define multiple sensing surfaces. Toroids may be seated in the grooves around each sensing surface for measuring the current flow through each sensing surface. Such placement enables a nearly ideal equipotential surface to be maintained and a straightforward “full coverage” electrode configuration due to a minimal electrode separation. Moreover, the disclosed configuration promises robust and reliable performance in the hostile conditions often experienced by logging while drilling (LWD) tools. This wall-contacting face can be provided on an extendable sensor pad or embedded on the outer surface of a LWD stabilizer fin.

摘要： A system and method for reducing borehole effects in a borehole within a subterranean formation is disclosed. The apparatus includes a fluid excluder, which includes a sleeve body and a sleeve opening defined by the sleeve body. The sleeve may be sized to fit around an induction tool. The sleeve body may include a fluid passageway therethrough, which may divert drilling fluids when the apparatus is deployed downhole. The apparatus may further include an electrode disposed within the fluid passageway for reducing the electrical current in the drilling fluid and thereby improve the readings obtained by logging devices.
