高效率清洗油田过滤器的超声波清洗技术

针对目前油田深床过滤器清洗效率低、清洗不彻底的现状 ,采用大功率超声波清洗流程及装置对核桃壳、纤维球和石英砂等 3种滤料进行了清洗试验 ,确定了最佳超声波频率为 4 0kHz ,每种滤料只需清洗 7min便可使水质达标。超声波清洗 1次的耗电量为 0 4 8～ 0 5 6kW·h ,是机械搅拌清洗所耗电量 (1 33～ 2 0kW·h)的 2 8%～ 36 % ;是水力搓洗所耗电量 (2 5～ 3 13kW·h)的 18%～ 19%。大功率超声波清洗具有清洗效率高、效果好、省时省电等特点。

New methods and technique for turbine oil cleaning

Maximally possible removal of free water from petroleum turbine oils (TO) is the primary goal in TO cleaning technology. Flow diagram of the installation and technology for TO cleaning are given and installations with 8–610 liters/h cleaning capacities are described.     

Pulsing filters in production of lube oils and waxes. Prospects for introduction

Studies on the development and introduction of a dynamic pulsing filter in production of base oils and solid waxes are continuing. The results of pilot tests of the filter and subsequent calculations demonstrated the high effectiveness of its addition in separation of wax suspensions. __________ Translated from Khimiya i Tekhnologiya Topliv i Masel, No. 2, pp. 12–15, March–April, 2007.     

国外保护油气层钻井液技术新进展

在油气钻探过程中,钻井液作为第一种入井流体,在对储层实施保护的过程中起着至关重要的作用.在长期的钻井实践中,我国已总结出三大类、共11种保护油气层的钻井液体系[1],但随着时间的推移和钻井难度的增加,保护油气层钻井液技术正面临着进一步发展和更新.近年来,国外高度重视开展保护油气层钻井液技术的研究,并已取得了较大进展和成功应用.
