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 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： A rotary coring device and method for acquiring a sidewall core from an earth formation adjacent a wellbore are provided. The rotary coring device includes a coring tool having a housing with a core receptacle therein and being adapted for positioning at selected depths within the wellbore. The coring tool further includes a first gear assembly operably coupled to a rotary coring bit. The first gear assembly is configured to rotate the rotary coring bit. The rotary coring device further includes an electrical motor configured to drive the first gear assembly for rotating the rotary coring bit at one of a plurality of rotational speeds. The rotary coring device further includes a hydraulic actuator configured to move the rotary coring bit in a first direction toward the earth formation for obtaining the sidewall core and to move the rotary coring bit in a second direction away from the earth formation.

摘要： An expert system is included in a downhole processor designed to acquire and process NMR data downhole in real time. The downhole processor controls the acquisition of the NMR data based at least in part on instructions transmitted downhole from a surface location and at least in part on evaluation of downhole conditions by the expert system. The downhole conditions include drilling operation conditions (including motion sensors) as well as lithology and fluid content of the formation obtained from other MWD data. The wait time, number of echos, number of repetitions of an echo sequence, interecho time, bandwidth and shape of the tipping and refocusing pulses may be dynamically changed.
