Design And Implementation Of The Field Data Transfer System For Integrated Logging

At present,in the oil and gas exploration service industry,comprehensive logging field data collection is large and timely,which is an important information source for oil and gas exploration.Due to working in the mud logging has the characteristics of wide distribution,dispersion,working in the field are far apart,traffic and communication inconvenience,combined with the lack of corresponding communication technology support,now still not realize remote real-time transmission of the logging data.In order to meet the demand of long-distance oil and gas exploration services,timely and accurate reference materials are provided to the exploration decision-making department,so it is necessary to realize remote real-time transmission of logging data.In satellite communication technology widely used today,with communication satellite build a base for oil and gas exploration and development of command,the drilling point to multipoint connection on the construction site,and make full use of,logging,information communication,network,database management,and other organic combination of technology,form the comprehensive logging data transmission system,to strengthen the comprehensive logging data management and analysis of information application has important significance.This thesis firstly introduces the background of this project,and introduces the present situation,trend and necessity of the field data transmission system at home and abroad.Starting from the basic theory of real-time data transmission technology,the basic principle and implementation method of real-time data transmission technology analysis and research,for the application of the late lay a solid theoretical foundation.The main research contents of this thesis are as follows:1.The functional requirements and non-functional requirements of the system are described in detail according to the user’s requirements for the actual functions.System functional requirements include user management requirements,rights management,query function demand,data import demand and statements of the functional requirements,non-functional requirements,including performance requirements and attributes.2.Designed the overall framework of the system,which consists of four parts,including data collection,data transmission,data reception and release,and system management.According to the POSC WITSML standard,the data transmission format of well field is defined,and three kinds of transmission modes are designed,such as real-time data transmission,timing data transmission and timely data transmission.3.Was designed and implemented in detail the main functions of the system,realized the multiple well receive at the same time,parameters,standardized management,standardized management,real-time data display and logging sketches,key technologies such as data backup to restore function.At last,the thesis introduces the realization of the system of the integrated logging data transmission system,including the key technology and the design of the system.This system applied in the field of oilfield of benefit for the oilfield enterprise at the same time,also for the construction of "digital oil field" play a positive role,also for subsequent topics related to the work laid the foundation.
