Presenting as a currency of total value of commodity, price is a central link in market mechanism; also , as a regulator of market, price has quite complicated forms. Oil transportation by pipeline is a significant component in national economic transportation system. In order to make pipeline industry keep abreast with the new market situation and constitute a price model of oil transporting by pipeline, which can response characteristics of operation in pipeline transportation enterprises, the article sets forth the function and feature of the price of piped oil, focusing on the analysis of the cost of piped oil and the relations between physical properties, flow rate of the piped crude oil and pipeline engineering coefficients, and also gives brief systematic analysis on major constitution elements of the piped oil price model.

价格作为商品价值全面的货币表现,是市场机制的中心环节,作为市场调节器,价格具有十分复杂的形态。管道输油是国民经济运输体系中的重要组成部分,为适应管道工业向市场经济转轨的新形势,构成反映管输企业经营运作特点的管道输油价格模型,对管道输油价格的职能及特点进行了阐述,重点分析了管道输油的成本与所输原油的物性、输量及管道的工程参数间的关系,并对管道输油价格模型的构成要素进行了分析。

The internal coating can prevent the wax deposition. The device simulating the dynamic wax growth is designed. The study is made on the ratio of inhibiting wax on the different coatings, the temperature differences between crude oil and pipeline wall,rotational velocity and the internal coating affecting the velocity of wax deposition. The test results show that with the time going on, the ratio of inhibiting wax is declined,and when the rotational velocity runs fast,the effect of preventing wax deposition...

The internal coating can prevent the wax deposition. The device simulating the dynamic wax growth is designed. The study is made on the ratio of inhibiting wax on the different coatings, the temperature differences between crude oil and pipeline wall,rotational velocity and the internal coating affecting the velocity of wax deposition. The test results show that with the time going on, the ratio of inhibiting wax is declined,and when the rotational velocity runs fast,the effect of preventing wax deposition is better. The temperature differences between crude oil and pipeline wall impacts slightly the wax deposition.

管道内涂层可以减少原油中的蜡在管壁上的沉积量,利用自行设计的原油动态结蜡模拟装置,对比研究了不同涂层的防蜡率,以及在不同搅拌转速和不同的油温及壁温下管壁内涂层对防蜡率的影响。结果表明,涂层的防蜡率随着时间的增长有下降的趋势;搅拌速度越大,防蜡效果越好;壁温和油温对防蜡效果影响不大。
