A coring tool (10), which includes a flexible wire mesh (28) in which the core is disposed, includes a mechanism for maintaining tension on the wire mesh sleeve (28) which then seizes the core disposed within the sleeve (28), and which serves to retain the core and maintain it under tension. The sleeve (28) is maintained under tension by tensile force transmitted to the sleeve (28) through a stripper tube (34). The stripper tube (34) is axially disposed through a piston ratchet assembly (50) connected to a piston (40) slidable within the tool member (16). The piston (40) is resiliently urged upward within the tool member (16) by a return spring (42) but is longitudinally forced downward within the tool member (16) and advanced downwardly with respect to the stripper tube (34) by an increase in pressure within the drill string thereby compressing the return spring (42). The piston ratchet assembly (50) prevents the piston (40) from moving longitudinally upward with respect to the stripper tube (34) and thereby allows the resilient force of the preloaded spring (42) to be applied through the piston (40) and piston ratchet assembly (50) to the stripper tube (34) as a tensile force on the wire mesh sleeve (28). A fixed ratchet assembly (52) is provided within the coring tool (10) to prevent any downward movement of the stripper tube (34) through the fixed ratchet assembly (52) thereby maintaining tension on the stripper tube (34) while the piston (40) is being advanced in response to an increase in fluidic pressure. A decrease in fluidic pressure allows the full force of the return spring (42) to be applied to the stripper tube (34). By means of this combination of elements the coring operation may be continuously practiced while the piston (40) is cyclically advanced compressing the spring (42); and the spring (42) allowed to relax as additional core length is cut; while all the time maintaining the stripper tube (34), sleeve (28) and core under tension. |

| Soil sampler comprising a sampling tube having a receiving space for receiving the soil sample to be taken, the receiving space being limited in radial direction by a wall, being open in distal direction for permitting soil to enter in it and in proximal direction being limited by a transverse wall, having line means for supplying and discharging fluid to the receiving space and with means for closing off the line means, a free plug or piston being placed in the receiving space closely fitting in there and moveable between the transverse wall and the distal area of the sampling tube and the transverse wall and the stopper or piston defining a sealed chamber for fluid when the stopper or piston is situated at a distance from the transverse wall. | ||||||
| 32 | Dual tube sampling system | US969752 | 1997-11-13 | US5854432A | 1998-12-29 | Arthur R. Vollweiler; Timothy J. Vollweiler |
| The invention pertains to the art of direct push soil sampling that uses the art of dual tube to retrieve subsurface soil samples. It is a means of applying the dual tube art that allows deeper sampling depths to be achieved by configuring the tooling string in such a manner that the inner tooling is non-rigidly attached to the outer tooling string both rotationally and axially. The non-rigidity of integration of the two tooling strings allows deeper penetration of the sampling apparatus by reducing the friction between soil entering the sample chamber of the inner tooling string and the sample chamber. In addition deeper depths of penetration are possible because the inner and outer tooling strings are driven both concurrently and independently of each other. | ||||||
| 33 | Process for manufacturing the inner tube element for a double tube coring apparatus | US560001 | 1983-12-09 | US4569710A | 1986-02-11 | Honore J. Lambot; Johannes H. M. Fliervoet; Pieter Kramer |
| The invention relates to a process for manufacturing an inner tube element made of synthetic resin for a double tube coring apparatus provided for deep boring. The tube element is provided with coupling nipples for connecting it to other inner tube elements. Fibers coated with synthetic resin are wound helically onto a cylindrical mandrel so as to overlap each nipple. This process gives the tube element a higher strength than that of glued nipples. | ||||||

| 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. | ||||||
| 35 | Method and apparatus for obtaining saturation data from subterranean formations | US152849 | 1980-05-23 | US4312414A | 1982-01-26 | Arthur Park |
| 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). | ||||||

| A core barrel having a hollow cutting ring is placed within a hollow drill and connected to a coupling which permits the core barrel to remain stationary while the bit rotates and also produces pressure to force the sharp edge of the cutting ring into the earth formation, the diameter of the cutting edge and inside of the cutting ring being slightly less than the internal diameter of the core barrel. A holder for a resilient sleeve, such as woven of nylon and is bunched onto the holder with the closed end of the sleeve across the open top of the holder, moves upwardly around the core as the core barrel moves downwardly and retains the core, particularly when from a soft formation or loose unconsolidated material, in the same relative position and shape as when cut. The inside diameter of the holder is intermediate that of the cutting ring and the core barrel. An adjustment means determines the axial spacing between the cutting edge of the core barrel cutting ring and the lower edge of the drill bit or teeth. | ||||||

| Mounted on the exterior of a non-rotatable core barrel is an end of a resilient tape the other end of which extends inwardly into the barrel and is connected to a device for pulling the tape inwardly into the barrel. The apparatus is also provided with an arrangement which forms a sleeve from the tape as this is being pulled into the core barrel. During the coring operation, the tape is being pulled inwardly into the barrel and a sleeve is formed from the tape with the aid of said arrangement to encase and protect the core from disturbance. The coring apparatus is intended for core drilling in soft, unconsolidated and fractured formations.
