Zusammenfassung:The invention relates to a neutron burst and measurement time sequence control method for stratum parameter measurement. The method comprises at least one combination measurement period which includes a fast pulse neutron burst period used for recording and processing borehole information and a slow pulse burst period used for recording stratum information. According to the neutron burst and measurement time sequence control method, a controllable pulse neutron generator is adopted for stratum parameter measurement, no high-strength chemical source is used, safety of a logging instrument is improved, and requirements for environment safety protection and personnel health protection can be satisfied. Via precision control of neutron bursts and measurement time sequences of the neutron generator, parameters such as a neutron porosity degree, a rock electron density of a stratum, a stratum thermal neutron macroscopic capture cross section sigma, an element content and the like can be synchronously and accurately
