Title: Method and apparatus for predicting optimal exploitation in shale oil in-situ conversion
Inventor: HOU LIANHUA
IPC: E21B43/30
Filed: 2020-02-24
Abstract: The disclosure provides a method and apparatus for predicting an optimal exploitation approach for shale oil in-situ conversion. The method includes: determining a lower limit temperature required for completely converting convertible organic matter in a shale to be measured into oil and gas, based on a pre-established relationship between the temperature rise rate and the lower limit temperature; determining an optimal well distance of heating wells, based on a thermal field parameter of a target reservoir of interest, an optimal heating time corresponding to the lower limit temperature, and a pre-established relationship between an optimal well distance of heating wells and the optimal heating time; determining an oil yield equivalent based on a temperature and an oil yield equivalent of the shale; determining an optimal well pattern; the lower limit temperature, the optimal well distance of heating wells, the oil yield equivalent and the optimal well pattern are optimal parameters. The above technical solution determines optimal exploitation approach for shale oil in-situ conversion based on optimal parameters obtained by optimizing key parameters during shale oil in-situ conversion and exploitation, so as to reduce the exploitation cost, and provide a scientific guidance for shale oil in-situ conversion exploitation.

Abstract: A method for efficiently scheduling virtual resource blocks to physical resource blocks is disclosed. In a wireless mobile communication system that supports a resource block group (RBG) allocation scheme, for distributed mapping of consecutively allocated virtual resource blocks to physical resource blocks, there is proposed a mapping method capable of increasing the number of distributed virtual resource blocks to a maximum while satisfying gap limitations, when the length of the physical resource blocks is different from the length of the distributed virtual resource blocks. Also, the number of distributed virtual resource blocks and the structure of an interleaver are limited for efficient scheduling.
