Title: Methods for thermal neutron diffusion coefficient logging
IPC: G01V5/10
Filed: 1973-08-21
Abstract: 1419888 Borehole logging TEXACO DEVELOPMENT CORP 21 Aug 1973 [18 Sept 1972] 39396/73 Heading G1A In a borehole logging system the earth formations are repetitively irradiated with bursts of fast neutrons, subsequent to a burst the thermal neutron population in the borehole is measured at each of two points spaced by different distances from the source and during two time intervals to produce four count signals which are combined to give a signal representative of the thermal neutron diffusion coefficient D in the vicinity of the borehole. The sonde contains a high energy neutron source or accelerator (11) which produces short bursts of fast neutrons under the control of a master clock (20). Two thermal neutron detectors (12, 13), which may be He<SP>3</SP> detectors, are arranged above a radiation shield (21) at different distances from the source (11). The signals from the detectors are passed to the surface and are both gated to counters during two short time intervals a sufficient time after the end of the source burst for strong borehole effects to die away. The resulting four counts are then combined in given ways to produce ratios which, together with a calibration constant representing the detector sensitivity ratio, are inserted into given equations to determine the thermal neutron diffusion coefficient D and the initial (notional) thermal neutron age To. These two values can be combined to calculate an enhanced value of the thermal neutron lifetime # o  and the porosity # may be determined from D by means of a calibration curve. The water saturation S w  can then be calculated from # and To. The porosity # and water saturation can be plotted on a chart as a function of the sonde depth. The counts from the two detectors are made over the same two equal time intervals but this is not essential. The calculations may be made by a suitably programmed digital computer.

Punched tape in zig-zag or rolled form is stored in a flattened thinwalled plastics tube 1 provided with identifying symbols &c., and with means for removably-securing the rear wall of the tube to an index card or like filing carrier. In one form, the tube 1 is cut from a length of transparent tubing, sealed at the base by welding or by adhesive, and has flexible metal tongues on the rear wall thereof for attachment to an index card. Fig. 4 shows a flattened tube 1 in which is a holding strip 7 of cardboard or plastics, which protrudes from both ends of the tube and is secured to the back wall by eyelets 8. A text or label is applied at 9 to the strip 7. An index card (11, Fig. 6) of board or plastics, has notches (15) at the bottom to facilitate staggered filing in a visible index system, and guide strips (14) secured by regularly spaced eyelets (8) to the top and bottom edges to form pockets to receive a number of tape containers. Another carrier (11, Fig. 11), is folded over and secured at its top and bottom edges (12, 13) to provide loops, the facing edges of the loops are notched at (20), and a rail (23) is passed through the top loop to act as a support for the carrier in a suspension file. Tape containers (1, Fig. 9), pass through slots in the top folded edge (16) of the carrier (11), and are located on the carrier by the engagement of eyelets (8) in the notches (20). The tape container (1) comprises an open-ended tube, as before, but the holder includes two strips (18, 19) which embrace the back wall of the tube and are fastened together at the bottom by an eyelet (8). The top edge of the back strip (19) is folded over on to the upper strip (18) and then folded back again to provide a free protruding tongue (21); an eyelet (8) is passed through the tongue and two strips. The front wall of the tube (1) has a finger cut-out (26) therein. When the container (1) is in position on the carrier (11, Fig. 11), the tongue (21) overlaps the notch (20), and at the bottom the strips (18, 19) embrace the folded over edge of the carrier. Further modifications (Figs. 12-22), of tape containers and a carrier therefor are described, wherein the thin-walled plastics tube (1) has a lesser length than the folded punched tape placed therein, so that the tape is readily removable. The holding strip can have tongues cut out therefrom, or have side extensions, to facilitate retention within the tube (1), and the upper end of the strip can be folded over to provide a pocket for an index tab. The index card or carrier and the tube (1) can be secured together by welding where they are made of weldable plastics; otherwise, staples or adhesive can be used. The index card or carrier has top and bottom guide strips secured thereto by spaced vertical strip weldings.
