Key Technologies Research Of Downhole Operation Data Center

At present, the downhole services sub-company basically have some application systems in running, about 70 sets, each department maintains the data which the department system needs, these systems do not have the integrated standard and data interaction, each application system is an 'Information Island'. Regarding such application systems, the identical data must be gathered and stored in the different application systems, it wasted time for users to carry on the data acquisition and precious memory resources, but also could not achieve rapid information linkage. Therefore, the downhole services sub-company proposed the 'one-one-six' project, namely a data center, a management platform, and six applications, in order to satisfy information support of the downhole process and realize the interoperability of the systems. Under this situation this topic is proposed as a research subject.In order to enable the data center to have the standard to follow, data elements theory, information resource planning theory, as well as data management theory are firstly studied, and based on above analysis, it defines the 'function area-business processes-business activities' triple system model of workover services process, and carries on the standardization to the downhole services process, under the guidance of the standard, carries on the modeling to the downhole services process. According to the research of the data element extraction method, it proposes a set of theory method system, and mainly carries on the data analysis and extraction to workover services process, and creates the system of data dictionary. Using POSC data modeling ideas and methods, inherited EPDM modeling idea, it creates the data model supporting the workover services process. Using the theory of Metadata Modeling it constructs the theme element model to describe and store the data dictionary. Finally based on these theme element models, it designs and develops the management system of the data dictionary, and implements the electronic management of the data dictionary.This thesis has been conducted by the research on key technologies and theories of the downhole services data center, it has developed the design and practice of the process modeling and data modeling based on the workover services process, the results of the research have established important basis for the construction of data center of downhole service sub-company. Based on these standards the downhole services sub-company has carried on the data gathering and archiving, gradually along with the development of the data center, it will provide efficient, integrated and shared data environment for the implementation of the'one-one-six'project.
