Research On Operation Performance And Security Support Technology Of Oil Field Data Center(OFDC)

Oil Field Data Center (OFDC)is the running entity of the Digital Oilfield , which comprises the main businesses of oil field enterprises about data. The core businesses of oil field firmly rely on the OFDC and the strong dependence poses the challenge to the operational quality and security of OFDC. As a multidisciplinary and comprehensive subject including both technology and management, it is extremely urgent to do the research on the operation efficiency, high availability, high reliability and high security of the OFDC and raise the tactics to the problems.Through consulting the materials about the running protect technology of information system from home and abroad, this paper would borrow the mature experience and advanced technology, analyze the main factors which influence the performance and security. And it put the emphasis on the work structure of OFDC, access mechanism of OFDC, data warehouse and query optimization technique, system load modeling, remote data backup strategy, business continuity,and finally gave the operating quality evaluation model of OFDC.1. OFDC work structure design: According to the demand characteristics of all fields in oilfield and the development direction of future, we design the work structure of OFDC. On the basis of integrating and using the existing resource, make the prioritization scheme and expansion scheme.2. Establishment of OFDC user access mechanisms: Through the unified user authentication platform of oilfield, we build the access mechanisms of OFDC in order to manage the access and permissions of OFDC. As a result, we can make the access target meticulous.3. Computation and Query optimization technology: Through proxy access and other technologies, we solve the efficiency problem of OFDC computation and access process and reduce the double counting. Using the concept of data space, we propose the implementation methods of multi-path query and the output of intelligent results, and focus on the research about the transmission, storage and query of large data volume.4. The test of network performance on OFDC: According to the network environment, we can do the delay test and quantify the efficiency of data transmission precisely. At the same time, we can get the personal testing result.5. The analysis of running process of OFDC: We firstly build the load model according to all functional modules, then abstract the OFDC as a single host, and finally develop the load model by the coupling of the sub-function modules. In practice, the load will be broken down to each operating part according to a recursive way. Through analyzing the critical value of load, we get the optimizing configuration proposal of network and server resources. Through analyzing the coupling relationship between access and load, we can solve the resource contention problems of large type of software of exploration and development in share.6. Remote data backup:Establish the OFDC data remote backup system, analyze the impact of data backup tasks on the overall operating performance of OFDC, propose an implement method of hot-swappable backup tasks and solve the unification problem between performance and security.7. Business continuity and operational evaluation: A solution of OFDC business continuity security system was proposed. By means of constructing analytical models such as running function, we can quantify the quality of the OFDC operation.8. Cloud services for OFDC building: Using the cloud service for the storage, computation, query and business continuity building of the OFDC, we can establish the data transfer model of business continuity, multi-loop, high stability in a complex network environment. Using cloud as a binder, we can make the distributed network become seamless via virtualization, logical technology and so on. We can reduce the management difficulties, improve operation quality and safety of OFDC via generalization.
