摘要： Coring tools including a core tube assembly; a carrier chamber defined within the core tube assembly for storing one or more core samples drilled from a downhole formation having a wellbore fluid therein, wherein the wellbore fluid has a wellbore fluid density; a non-hydrocarbon, non-reactive heavy weight fluid (“HWF”) present within the carrier chamber, the HWF exhibiting a HWF density of about 2 pounds per gallon greater than the wellbore fluid density; a pressure housing cover selectively rotatable between (1) an open position, where the one or more core samples are able to be inserted into the carrier chamber, and (2) a closed position, where the carrier chamber is sealed; and a cover activation mechanism coupled to the core tube assembly and operable to move the pressure housing cover between the closed position and the open position.

摘要： Methods of procuring a core sample may involve engaging an earth formation with a cutting structure of a coring bit. A core sample may be received within a receptacle connected to the coring bit, the receptacle being lined with a sponge material. A space of about 1 mm or less may be maintained between the core sample and the sponge material. Coring tools may include a coring bit comprising an inner gage and an outer gage and a sponge material positioned to at least partially surround a core sample cut by the coring bit. A radial distance between an inner surface of the sponge material and the inner gage of the coring bit may be about 1 mm or less. A distance between a center of curvature of the inner gage and a center of curvature of the outer gage may be about 0.3 mm or less.

摘要： The present disclosure is related to an apparatus for taking a sample in a wellbore during drilling operations. The apparatus may include a drill bit configured to form a core and at least one retractable cutter internal to the drill bit for taking the sample from the core. The apparatus may also include equipment for analyzing the sample, extracting fluid from the sample, testing fluid from the sample, encapsulating the sample, and/or tagging the sample. The present disclosure is also related to a method for taking a core sample without interrupting drilling operations. The method includes taking a core sample using a drill bit configured to take a core sample using internal cutters. The method may also include analyzing the sample, extracting fluid from the sample, analyzing fluid from the sample, encapsulating the sample, and/or tagging the sample.

摘要： A selectively operable downhole valve for use with core sampling apparatus, the valve comprising a throughbore through which a first body may pass, and an obstructing member which is capable of selectively obturating the throughbore, the obstructing member being arranged to open or close the throughbore by movement of the first body with respect to the valve. A core sample of the formation may then be obtained and retrieved from the bore under pressure since the valve seals the bore downhole. Retrieving the sample under pressure maintains the integrity of the core sample so that subsequent analysis of the sample will more closely reflect the true characteristics of the formation.

摘要： A well coring apparatus (10) includes an outer barrel (12) and an inner barrel (18). The inner barrel (18) is sealed with a rupturable diaphragm (24) and a check valve (49). A sponge (50) is disposed around the inner walls of the inner barrel (19) for contacting the core (58). A fluid (54) is disposed in the sealed inner barrel (18) to prewet the sponge (50). A piercer (32) is reciprocally disposed within the outer barrel (12) and has a conical shaped surface (38), the apex of which is operable to pierce the diaphragm (24). In response to forming of the core (58), the fluid (54) displaced by the core (58) prevents drilling mud from being disposed between the core (58) and the sponge (50).

摘要： A core barrel holder for supporting a core barrel during removal of a core sample from the core barrel. The core barrel holder includes a housing, an inner sleeve, a plurality of support elements extending radially inwardly within the inner sleeve, a spring, and a cap. Upon positioning of the core barrel holder in an operative position, the inner sleeve receives the core barrel. Upon advancement of the core barrel through the inner sleeve, the plurality of support elements frictionally engage the core barrel within the inner sleeve.
