Shengli Oilfield Well Analysis And Implementation Of Heterogeneous Data Integration

With rapid development and enhancement of the information construction andnetwork environment of Shengli Oil Field，the mode of information operation andmanagement are becoming complex. Departments in some oil fields lay stress oninformation resources building and management, as a result, lots of data is graduallyaccumulated. However, these data has such following features: first, the data form andthe storage format are not unified; second, the data volume is very large and thereal-time processing are highly demanded; the third, there are complex relationshipsbetween and among the distribution and the storage of the data, meanwhile, with theredundancies and inconformity existing. These characteristics make the data-exchangebecome complex, so careful analysis is urgently needed, and a uniform data access mustbe built, so as to solve the problems in heterogeneous data. With the above works, theproduction and decision-making process can get a real-time and effective data query anddata sharing service.Based on the “Oil&Gas Engineering Assistant” project, this paper researches thecore technical difficulties in production engineering domain data integration withheterogeneity, integrity, expansibility, etc. and proposes the project of “Data IntegrationBased on Multiple Mapping Rules for Production Engineering” to provide powerfuldata support for decisions of well production. The main work is summarized as follows:(1) Design and develop the Integration system. It is divided into three layers:original data layer, middle data layer, and standard data layer. Heterogeneous databasesystem is the first layer; the second layer is the core of integration scheme and it realizesdata integration; last layer storage standard data support to upper application.(2) Propose and realize Data integration methods which includes four stages: dataconnection adaptation, data acquisition, data processing and data transmission.According to various typical data, design a series of integrated strategy forheterogeneous, change complicated heterogeneous data into standard and unified datamodel with multiple mapping rules. (3) Display specific examples, with explicitly stating the realization of the mainmodules in “Integration Based on Multiple Mapping Rules for Production Engineering”,verify the feasibility of the scheme.
