9 results about "Logging" patented technology

Logging is the cutting, skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. Logging is the process of cutting trees, processing them, and moving them to a location for transport. It is the beginning of a supply chain that provides raw material for many products societies worldwide use for housing, construction, energy, and consumer paper products. Logging systems are also used to manage forests, reduce the risk of wildfires, and restore ecosystem functions.

Method and device for managing terminal data logging

ActiveCN101923571AShorten the lengthObvious advantage of storage spaceDatabase distribution/replicationSpecial data processing applicationsUniversally unique identifierUnique identifier
The invention discloses a method and a device for managing terminal data logging. The method comprises the following steps of: distributing an LUID (Local Unique Identifier) for each data logging of a terminal; distributing a UUID (Universally Unique Identifier) for the storage position of each data logging of the terminal; respectively establishing the mapping relationship between the LUID and the UUID for each data logging of the terminal; respectively concealing the corresponding UUID at each storage position in a change log file; changing values of change log items in the change log file by using the established mapping relationship of the LUID and the UUID when the data logging is non-synchronously operated; and executing synchrotrons operation of the data logging by using the established mapping relationship of the LUID and the UUID and the values of the change log items of the change log file when the data logging is synchronously operated. The invention manages the change log items in the change log file by using the mapping relationship between the LUID and the UUID, thereby greatly reducing the length of the change log file and the operation complexity of the change log,and simplifying the operation and the maintenance of the whole change log file.

Array electric imaging logging based reservoir oil-water identification method and system

ActiveCN102678102AGroundbreakingPracticalSurveyConstructionsEngineeringLogging
The invention relates to an array electric imaging logging based reservoir oil-water identification method and system. Aiming at the resistivity distribution characteristics of mud-invaded formations, a 'five-parameter formation model' is established, which is adapted to the requirement for simulating the resistivity distribution characteristics of different mud types and different invaded formations, and is pioneering in the aspects of forward-inversion models and processing methods of array electric imaging logging; and based on a 'five-parameter inversion' method for array electric imaging logging, an operation of carrying out resistivity distribution profile reconstruction on mud-invaded formations is performed, which reflects the actual differences between different resistivity distribution characteristics or change rules of mud-invaded oil formations or water formations. The method has stronger practicability, and is pioneering in the actual application aspects of qualitative identification and quantitative calculation on reservoir fluid properties.

User logging-in method under system control

The invention provides a user logging-in method under system control. The method comprises: a user logs in a system; the system determines whether the logging in is realized by means of manual inputting or USB Key; if the logging in is realized by using a USB Key, the information in the USB Key is read by the system and the user inputs card number and password information, so that the user can log in the system without being limited by an IP and an Mac address; and after USB Key acknowledge, the system sends a random short-message verification code to the user, the user inputs the verification code and can not log in the system until the verification code is correct, and the system checks the correctness of the verification code and thus the logging in is done successfully. And if the logging in is realized by the manual logging in way, the user inputs a user name and a password; after the information is checked to be correct, the system sends a random short-message verification code to the user; the user inputs the verification code and can not log in the system until the verification code is correct, and the system checks the correctness of the verification code and thus the logging in is done successfully. Compared with the prior art, the method has advantages of high practicability, security and flexibility.

Method for performing weight analysis on main control factors of logging parameters in water-oil-gas reservoir

InactiveCN108533254AOvercoming shortcomings in weight analysisAvoid blindnessBorehole/well accessoriesCorrelation analysisSingle measure
The invention relates to a method for performing weight analysis on main control factors of logging parameters in a water-oil-gas reservoir. The method is characterized by comprising the following steps: 1, collecting and sorting various characteristic parameters measured by each single technology in geochemical logging, collecting oil testing conclusions corresponding to each group of characteristic parameters, and then cleaning and verifying integrated data; 2, performing standardized processing; 3, writing a ReliefF characteristic selecting program by using Matlab software, and establishinga ReliefF algorithm model for geochemical logging measurement analysis; 4, inputting standardized data into the ReliefF algorithm model, and calculating weight values of the various characteristic parameters measured by the single technology by using the RelefF algorithm model; 5, setting thresholds, screening characteristic subsets, and extracting geochemical logging sensitive parameters. The method and a gray correlation analysis method have different emphases; by the method, the defects of the gray correlation analysis method in the weight analysis are overcome; the method belongs to supervised learning.
