Abstract:
The present invention provides a method and a device for measuring a formation elemental capture gamma ray spectrum, pertaining to the field of oil-gas exploration and well logging technologies. The method comprises: performing moderation on neutrons emitted from a neutron source according to a neutron capture cross section of a test sample; and adjusting a relative location of the test sample with respect to the neutron source, so that a standard capture gamma ray spectrum of the test sample is measured and obtained at a location where a thermal neutron flux reacting with atomic nucleuses of the test sample reaches a first predetermined value. The present invention performs moderation on a neutron source according to neutron capture cross sections of different test samples to measure and obtain elemental capture gamma ray spectra of the test samples, thereby obtaining various formation elemental capture gamma ray spectra with higher accuracy.

Claim (Index 14):
A measuring device for the method for measuring a formation elemental capture gamma ray spectrum, the device comprising: a measurement body, a second moderation shield, a detector, a data collecting and processing module and a data analyzing module,\n wherein the second moderation shield and the detector are arranged in the measurement body, the second moderation shield is used for loading the test sample and performing moderation on the neutrons emitted from the neutron source at the outer side of the second moderation shield, wherein the second moderation shield is movable, so that the detector acquires prompt gamma ray spectrum data of the test sample at a position where the thermal neutron flux reacting with atomic nucleuses of the test sample reaches a first predetermined value, wherein the data collecting and processing module collects and processes the prompt gamma ray spectrum data acquired by the detector, and wherein the data analyzing module analyzes the prompt gamma ray spectrum data and obtains the standard capture gamma ray spectrum of the test sample.
