摘要： A core drilling mechanism in an elongate housing is rotated from a vertical storage position to a horizontal operable position. This permits the transport downhole of a drilling mechanism of sufficient longitudinal dimension to drill a core sample of substantial length perpendicular to the borehole sidewall. A fixed slotted plate and hydraulically actuated rotatable drive plate control the motion of the drilling mechanism, which is stored vertically for descent and ascent, and rotated 90-degrees and moved outward for core drilling. After a core sample is drilled, the drilling mechanism is tilted upward to break off the core, and then returned to its vertical storage position.

摘要： An apparatus operable on a wireline logging cable for drilling a hole in the sidewall of a drill hole which comprises a hydraulically operated backup shoe (20) for wedging the apparatus at a selected location in the drill hole, a hydraulic motor (32) with a drilling bit (31) connected thereto for rotation by the hydraulic motor and hydraulic means (34, 35) connected to the hydraulic motor for motor for moving the bit into drilling engagement with the sidewall of the drill hole. In the improvement of this invention, the hydraulic means for moving the bit into drilling engagement comprises a new flow restrictor valve (147). This flow restrictor valve has an orifice (159) and a slender pointed rod (151) for restricting the flow of fluid through the orifice. Opposing spring means (153) and control fluid means engage the rod for controlling its movement toward and away from the orifice. A method of sidewall coring is also disclosed.

摘要： A method for estimating elastic properties of a subsurface material having a bedding plane includes disposing a single sample of the subsurface material in a core holder, the core holder having (i) a first acoustic transducer set having a first acoustic source and a first acoustic receiver and (ii) a second acoustic transducer set having a second acoustic source and a second acoustic receiver. The method also includes performing at least five acoustic wave velocity measurements on the single sample that include compressional acoustic wave velocities and shear wave acoustic velocities with a certain direction of shear acoustic wave polarization using the first set of acoustic transducers and the second set of acoustic transducers, estimating, with a controller, the elastic properties using the at least five acoustic wave velocity measurements, and providing an output signal having the elastic properties to an output signal receiving device.

摘要： A disclosed effective porosity determination method for tight gas formations includes: obtaining a core sample sealed in a pressure-maintaining core vault during transport out of the borehole; coupling the core vault to a collection chamber; based at least in part on measured pressure, temperature, and fluid volumes in the collection chamber, deriving the number of moles of gas retrieved with the core sample; and combining the number of moles with a downhole pressure, a downhole temperature, and a downhole core sample volume to determine an effective porosity of the tight gas formation. A system embodiment includes: a coring tool having a core vault with a seal to provide pressure-preserved transport of a core sample from a tight gas formation; a collection chamber that attaches to the core vault to measure volumes of fluids and gas; and a processing unit that responsively determines an effective porosity of the tight gas formation.

摘要： The invention relates to a method for operating a horizontal drilling device which comprises a linear drive, a rotary drive that can be displaced by means of the linear drive, and drill pipes that are designed as a string of drill pipes from a plurality of interconnected pipe strands, the rotary drive forming a through-opening into which the drill pipes can be inserted. The through-opening is provided with force transmission means for transmitting compressive and/or pulling forces and/or a torque onto the drill pipes. The invention is characterized in that a pipe strand is fixed inside the through-opening of the drill pipes and is connected to the rear end of the drill pipes or detached from the drill pipes by a linear and/or rotary movement of the rotary drive.

摘要： Discloses is a method for analyzing the soil, in which a borehole is drilled in order to take a measurement and/or a sample of the soil, a gas, and/or a liquid. The borehole is furnished with a pipe (1), the wall of which comprises at least one area (11) that is easy to pierce, before the measurement or the sample of the soil and/or liquid is taken. The area (11) that is easy to pierce is penetrated by means of a measuring probe and/or sample probe (5) in order to take the measurement and the sample of the soil, gas, or liquid.
