Study On Evaluating Performance Of Injecting Pipeline Network In The Oilfield

The oilfield injection system is one of five large-scale systems in oilfield surface engineering. water injection is an effective and important measure adopted in oilfield to keep formation energy, enhancing crude oil recovery ratio, insuring long-term high and stable Production. Water injection system dissipates large mount of electric energy of the total energy consumption in oilfield. However, low efficiency and energy waste exist in water injection system in almost all oil fields in our country. For a long time, each oilfield has paid much attention to compatibility of injected water, water quality, water quality management technique, and there are few research on the oilfield surface engineering, usually they design and transformation depended on experiment and trial-and-error method. At present most researches are study on the oilfield water injection system energy consumption, the system simulation, the optimization research and so on, there are few men consider the simulation optimizes, system energy consumption analysis and transformation as whole research. Therefore this paper research on evaluation of whole pipe network's performance preliminary.The paper is research on approach to evaluate performance in oilfield water injecting pipeline network. Mainly carries on the oilfield injecting pipe network's macroscopic overall service performance evaluation, proposed the oilfield flooding pipe network's three principles: to evaluation on the oilfield flooding pipe network's reliability, sufficiency, efficiency. Has given the performance quantitative evaluation systematized method about injecting pipeline network. First aims at the different appraisal system designation related state variable, then draw the standard service performance curve which can be definite the element level performance index to the state variable change rule, Finally choice the induction function development the element level performance evaluation to obtains the entire pipe network's performance index value. Determined that after whether should make the transformation, carries on the microscopic analysis again, discovery the existence question in injecting system, carry on quantifying the oilfield flooding pipe network's evaluation criteria. It has provided to transformation and how to transform based on the scientific basis.
