摘要： An apparatus (10) and method for obtaining oil and water saturation data from subterranean formations includes a drill bit (12) for boring a well core (26) containing the fluids. A core-catcher bowl (18) guides the well core (26) in the apparatus (10). An outer barrel (14) is attached to the drill bit (12) and contains the core-catcher (18). An inner liner (20) positioned in the outer barrel (14) receives the well core (26). An oil absorbent sponge-like member (22) is contained in the inner liner (20) with a diameter (24) for receiving the well core (26). The oil absorbent sponge-like member (22) absorbs the fluids contained in the well core (26).

摘要： A packaged core is obtained using a conventional core barrel system. A lining is provided in the core sample container of the core barrel. The core barrel is connected to a drill string extending into a borehole. As the drill string is rotated, the core sample moves into the sample container and inside of the lining. When the core barrel arrives at the surface, the sample core may be removed from the core barrel packaged in the lining. The core may be examined on site or the ends of the lining closed and the core completely packaged for shipment to the laboratory.

摘要： A formation coring apparatus suitable for coring relatively soft formations which apparatus includes a core barrel with an interior surface having properties similar to synthetic rubber and two semitubular rigid portions joined along at least one of the adjacent edges by a flexible material, a core catcher having a plurality of flexible segments adapted to open while the core is being drilled and to close with the segments supporting the core thereabove to recover the core, a coring bit and a wire line tool adapted to carry the core barrel and the core catcher into position within the coring bit and having a fishing neck to be engaged by a wire line device for recovery, a latch for retaining the tool in position within the coring bit, a swivel allowing the core barrel and catcher to remain stationary while the coring bit is rotated and a check valve allowing fluid flow from the top of the core barrel because of the entry of the core therein to flow out the tool while preventing inflow of fluids into the top of the tool.

摘要： Large-diameter, undisturbed soil core samples were obtained from a variety of soils. Handling and fracturing of the undisturbed soil cores were minimized by encasing the cores in heatshrinkable plastic tubes during sampling operations.

摘要： An improved apparatus for taking an undisturbed soil sample supported by a flexible hose and an additional supporting tube which is coaxially positioned within the sampling tube proper, provided with clamping fingers for pinching off the supporting tube in the lower part of the sampling tube for keeping the sample within the supporting tube when the sampling tube is retracted from the soil, which fingers are operated by wedges when two mutually slidable parts of the sampling tube are moved by changing from pressing to pulling.

摘要： A core barrel device for producing and retrieving subterranean cores, particularly from soft or unconsolidated formations, utilizes a fluid-pressure collapsible sleeve above the corer to receive and hold the core material and permit its retrieval in its original subterranean condition. Pressure responsive valves maintain a fluid pressure behind the collapsible sleeve to retain it in the collapsed position until the core is received in the sleeve and also permit fluid behind the sleeve to exhaust as the core enters the sleeve while the sleeve continues to offer lateral pressure support for the core and also remains collapsed above the core. When the coring device is withdrawn, a small amount of core material falls from the lower portion of the core barrel and the lower portion of the sleeve collapses to retain the remainder of the core within the core barrel.
