| 61 | Rotary sidewall sponge coring apparatus | US314247 | 1994-09-28 | US5439065A | 1995-08-08 | Daniel T. Georgi |
| The invention is an apparatus for rotary drilling of core samples from the wall of a wellbore. The apparatus comprises a coring bit, a motor, a bit box rotatably mounted within a housing adapted to traverse the wellbore, a plunger for extracting the core sample from the bit and discharging the core sample into a storage barrel which has a sponge liner. The sponge liner in the barrel adsorbs liquid hydrocarbons which may be expelled from the porosity in the core sample by gas exsolution. | ||||||
| 62 | Core barrel apparatus for disposing a core within a thin, flexible film casing | US707895 | 1985-03-04 | US4643265A | 1987-02-17 | Noboru Aiura; Yoshio Sawaki |
| An unconsolidated or loose core is retrieved and retained within a coring tool by wrapping the core with a resilient thin film sleeve. The sleeve is compacted and stored within a concentric cylindrical storage space outside of the core and within the tool. The thin film compacted sleeve is then drawn from the storage space and wrapped about the core. The thin film sleeve is characterized by having a longitudinal length several times greater than the corresponding longitudinal length of the storage space in which it is compacted and stored. More particularly, the thin film sleeve is compactly stored in a cylindrical space defined within an inner tubular mandrel concentric with the core and an outer tubular mandrel concentric with the core. The two mandrels are concentric with each other and spaced apart to form an annular circumferential opening through which the thin film sleeve is disposed and drawn. The thin film sleeve is coupled to a guide plug, which is axially disposed and longitudinally displaceable within the core barrel of the coring tool. When the core is disposed into the core barrel, it comes in contact with the guide plug which is then displaced relatively upward within the coring tool, drawing the compacted thin film sleeve from its cylindrical annular storage space about the concentric core within. Typically, the thin film sleeve is a 4 mil resin, plastic or rubber tubular, cylindrical sleeve. | ||||||

| A coring tool, which includes a flexible wire mesh in which the core is disposed, includes a mechanism for maintaining tension on the wire mesh sleeve which then seizes the core disposed within the sleeve, and which serves to retain the core and maintain it under tension. The sleeve is maintained under tension by tensile force transmitted to the sleeve through a stripper tube. The stripper tube is axially disposed through a piston ratchet assembly connected to a piston slidable within the drill string. The piston is resiliently urged upward within the drill string by a return spring but is longitudinally forced downward within the drill string and advanced downwardly with respect to the stripper tube by an increase in pressure within the drill string thereby compressing the return spring. The piston ratchet assembly prevents the piston from moving longitudinally upward with respect to the stripper tube and thereby allows the resilient force of the preloaded spring to be applied through the piston and piston ratchet assembly to the stripping tube as a tensile force on the wire mesh sleeve. A fixed ratchet assembly is provided within the coring tool to prevent any downward movement of the stripper tube through the fixed ratchet assembly thereby maintaining tension on the stripper tube while the piston is being advanced in response to an increase in fluidic pressure. | ||||||

| An improved coring device that incorporates a nonrotatable inner barrel disposed within the outer driving structure of the drill string which is coupled to a coring bit. A woven metal mesh sleeve is circumferentially mounted outside the inner barrel and tucked around its lower end. The lower end of the mesh sleeve in the inner barrel is in turn connected to a stripper tube which is pulled upwardly during the coring operation. As the core is cut by the coring bit and enters the inner barrel, the woven metal mesh sleeve is disposed about the core and constricts about the core when pulled upwardly by the stripper tube. The opposing end of the woven metal mesh sleeve is connected to a weight which serves to compress the metal sleeve when outside the inner barrel, thereby increasing its diameter to prevent binding or jamming. | ||||||
| 65 | Sponge coring apparatus with reinforced sponge | US513376 | 1983-07-13 | US4502553A | 1985-03-05 | Arthur Park; Bob T. Wilson |
| A well coring apparatus (10) includes an outer barrel (12) and an inner barrel (18). A hollow sponge (50) is disposed along a liner (52) for insertion into the inner barrel (18). The sponge (50) is operable to absorb subterranean fluid from a well core (54). A plurality of reinforcing members (56) are disposed on the inner surface of the liner (52) to prevent movement of the sponge (50) with respect thereto. A plurality of orifices (58) are disposed in the surface of the liner (52) to allow gas and/or fluid to escape from the interior thereof when the subterranean fluid contained within the core (54) bleeds into the sponge (50). | ||||||

The apparatus includes a container for receiving the sample and is characterised in that the container comprises at least one wall with a surface which can change its configuration in response to pressure changes. A method of handling a geological sample obtained from a formation is also described and includes providing a container for receiving the sample. The container has a surface which is capable of changing its configuration in response to pressure changes. The sample is introduced into the container, and the configuration of the surface is changed to contact the sample. The container is then withdrawn from the formation. |

An improved coring device that incorporates a nonrotatable inner barrel (50) disposed within the outer driving structure (12) of the drill string which is coupled to the coring bit (30). A woven metal mesh sleeve (105) is circumferentially mounted outside the inner barrel (50) and tucked around its lower end (112). The lower end of the mesh sleeve (105) in the inner barrel (50) is in turn connected to a stripper tube (40) which is pulled upwardly during the coring operation. As the core is cut by the coring bit (30) and enters the inner barrel (50), the woven metal mesh sleeve (105) is disposed about the core and constricts about the core when pulled upwardly by the stripper tube (40). The opposing end of the woven metal mesh sleeve (105) is under a weight (126) which serves to compress the metal sleeve (105) when outside the inner barrel (50), thereby increasing its diameter. The plurality of wedge-shaped segments (125) located on the top of the sleeve (105) are collectively brought together to form a core catcher when that end of the woven metal mesh sleeve (105) to which the segments (125) are connected is drawn around and into the lower end of the inner barrel (50). |
