| titleOfInvention | Cold and hot neutron detector for oil well logging and lithium glass fiber preparation method |
| abstract | The invention provides a cold and hot neutron detector for oil well logging and a preparation method of lithium glass fiber, wherein the detector comprises a detector main body, a photomultiplier and a coupling layer arranged between the detector main body and the photomultiplier, and also comprises a lithium glass fiber layer and a total reflection layer arranged on the outer end surface of the lithium glass fiber layer, and the detector main body and the lithium glass fiber layer form an integral core glass layer through a casting forming process; in the scheme, the lithium glass fiber layer on the detector is formed by tightly arranging a plurality of layers of glass fibers, and the lithium glass fiber layer and the detector main body are manufactured into an integral core glass layer by adopting a casting forming process, so that the whole detector is easier to manufacture; in addition, the lithium glass fiber material is prepared by an improved lithium glass and fiber preparation method by adopting a platinum-substituted crucible wire drawing process, so that the detection efficiency of high-efficiency neutrons can be ensured, and compared with the traditional detector, the lithium glass consumption is less, so that the detection performance and the manufacturing economy of the detector are improved. |
