    摘要: A pressure and temperature core sampler comprises a tool for recovering cores specifically enabling the evaluation of methane hydrate resources. Because methane hydrate tends to decompose under conditions of pressure decrease and/or temperature increase as the samples are retrieved to the surface, a coring tool in accordance with the present invention provides a self-contained system for retrieving core samples at or near in situ pressure while cooling the core sample. The coring tool is preferably a wire line retrievable device that provides for nearly continuous coring during the drilling operation.

    摘要: A simple low-cost and highly passive bitless nonrotational nondeviating jam-proof thin-kerf Newtonian hydraulics retrievable core-sampling method and apparatus that advances its circular core kerf through the rock by a combination of high-pressure droplet-impact and abrasive particle-jet effects, and which is independent of the weight of any drillpipe, drill collars, or any other heavy cylindrical conduit or tubular conduit associated with the coring operation. The Newtonian hydraulics features high-pressure solids-free fresh water or solution-weighted brine as the drilling fluid, which excavates rock along the inner periphery of the circular core kerf by droplet-impact effects of the high-pressure and high-velocity circular sheet of drilling fluid and by the abrasive particle-jet effects of the deflected drilling fluid and excavated rock particles along the outer periphery of the circular core kerf. The hydraulic horsepower delivered to the downhole coring apparatus and the hydraulic hoisting capacity of the excavated rock particles to the surface can both be increased considerably by employing high-density solution-weighted brine as the drilling fluid. The use of solution-weighted brine, if chilled at the surface to below the freezing point of the penetrated porefluid, and if circulated in the borehole by means of insulated drillpipe, would also provide the additional advantage of freeze-stabilizing the borehole wall, freeze-stabilizing the excavated core samples, and freeze-entrapment of uncontaminated porefluids in the core samples.

    摘要: Jamming caused by absorbent members in sponge core barrels or loss of coring information caused by oil wipes in oil field boreholes in which sponge core coring tools are disposed can be avoided by employing a method and tool wherein the absorbent member is formed in placed in contact about the core after the has been cut and disposed within the inner tube. In the illustrated embodiment, a liquid foam is catalytically formed from two constituent parts. The constituent parts are hydraulically forced from longitudinal chambers defined within the inner tube walls into an area in the throat of the bit where the parts meet and exothermically generate a liquid foam. The liquid foam rises into a plurality of longitudinal open chambers defined within the inner tube. Each of the open chambers has a longitudinal slot defined therethrough which communicates the chamber with the axial bore in which the core is disposed. The liquid foam flows into the longitudinal chambers and into the annular space between the inside surface of the inner tube and the core. Ultimately, the core is totally immersed in the liquid foam. Thereafter, within a predetermined curing time, the liquid foam cures to form a sponge-like solid. The oil bearing core may not be retrieved to the well surface. As the core is depressurized during retrieval, oil forced from the core by escaping water and gas is retained within the sponge for later analysis.

    摘要: A method for determining the productivity of a well site includes extracting a core with sponge coring techniques and measuring the parameters of the core. The parameters measured are porosity, permeability and percent mobile oil. A core factor is calculated which is the square root of the product of permeability and porosity and indicates the space available in the core for oil production. The core factor is multiplied by the percent mobile oil to provide a Production Index. The Production Index indicates the capacity of a given oil well to produce oil. With the Production Index data, perforations are selectively placed in various areas along the longitudinal axis of a well casing (38) to selectively allow communication between the interior of the well casing and a formation of interest. In this manner, only areas having high oil mobility are communicated within a given region of the formation of interest.

    摘要: This invention relates to improvements in pressure core barrels of the type described in U.S. Pat. No. 3,548,958 wherein a controlled pressure is maintained on a core sample during surfacing. Among the improvements provided by the present invention are an improved arrangement of the pressure control valve, a device for positively latching the assembly (both in the open and closed positions) and the provision of a hydraulic assist for moving the outer barrel to the sealing position. Another particular feature provides an improved device for flushing drilling mud from the core barrel mechanism with sealing valve open and while the core sample is maintained substantially at a pressure at which it was sealed in the bore hole and to facilitate subsequent freezing and removal of the core sample therefrom for analysis.
