[Abstract]:In the production and operation of long distance oil and gas pipelines, any fault in any position may lead to oil leakage accidents, causing great losses to the environment, personnel and property. Integrating the pipeline construction information data, evaluating the operation flow of the station yard, using computer technology to avoid the defective pipeline automatically, seeking the economical and efficient oil product transportation path, monitoring the pipeline operation in real time. It is an effective way to prevent pipeline accidents. The paper collects and normalizes the information data of welding material inspection for long distance pipeline, and establishes a database including pipe inspection, field mouth inspection, process evaluation, performance inspection and so on. Based on C / S structure, a welding material inspection and management information platform is developed by using object-oriented technology, which has the functions of information audit, query, maintenance, display, output and so on. On this basis, the system of station yard operation guidance is defined as node on the basis of analyzing the process flow chart of station yard. For the first time, risk factors are introduced into the mathematical model of optimization process of oil transportation station. The structure of station yard is described by directed graph, and the directed subgraph is calculated by using Hopfield neural network, and the corresponding energy function and solution method are given. The optimal pump combination is applied to the dispatching task of the oil transmission station to improve the reliability and efficiency of the station. The operation guidance system of oil transportation station with dynamic display function is developed by using Delphi. On the basis of reading IP21 real-time production database, the system can realize the research of operating mode simulation and field dynamic simulation, etc. The system has been successfully applied to a large oil transportation station in China. The actual operation shows that the construction data acquisition information platform and the station operation guidance system developed are feasible and effective, standardize the construction and office flow of the enterprise, reduce the labor intensity on the spot, improve the production efficiency, and ensure the operation safety.
