本文从理论上分析了高粘度原油洗舱的可能性，介绍了模拟试验台系统和用大庆原油进行洗舱试验的结果，提出了高粘度原油洗舱方法的基本要求、条件及清洗的工艺程序。

The evaporation of some oils and their emulsifies was modeled with pan evaporation method, and the characteristics of the evaporation in different states was inspected.

结合原油组分特点，认为过去将原油蒸发当边界层控制来处理，以及以纯水蒸发速率方程为基础通过修正而建立起的原油蒸发速率方程是缺乏理论根据的。

Large quantity of sand body provide a reservoir for crude oil, faults and strata erosion form the channel for oil to migrate, and the compact mudstone keeps crude oil from volatilizing, oxidizing and biodegradation.

西部斜坡大量发育的砂体为运移至此的原油提供了储集体，大量的断层和地层剥蚀形成的不整合面提供了原油的运移通道，砂体上的致密泥岩阻碍了原油组分的大量挥发、氧化和生物降解。

In order to prevent the acid sludge forming during acidizing treatment for Putaohua formation in Daqing peripheral oilfield, the research on colloid and bitumen in oil, acid system, ferric ion and anti -sludge agent has been carried out to determine the possibility of sludge forming.

从立足于研究大庆外围葡萄花油层原油防止酸渣形成的方法入手，从原油胶质沥青质、酸液类型、三价铁离子和各种类型的抗渣剂等方面，考察了大庆外围葡萄花油层的原油与酸接触，形成酸渣的可能性。

Combined with global resources and processing conditions of high acid oiland domestic existing problems,analyzed price ad- vantages and technical feasibility under high oil price,presented views such as we should speed up development of pro- cessing of oil wit high acid,and trial in one of two.
