文昌油田群在开发过程中,随着开发时间的增加,采液量不断提高,地下岩层逐渐松动,各种粉砂岩、地层砂随着原油进入生产系统,不但对井口平台设备如过滤器、外输泵、管线等造成损害而且极大的降低了油品质,直接影响经济效益。通过不断的对动态旋流技术进行试验研究,结合文昌油田群的特征,成功开发出独具特色的动态旋流除砂器,并在文昌油田群应用。从2012年1月1号运行以来,共排砂500Kg,除砂率达到90%以上,除砂最小粒径达到15μm。
Wenchang Oilfield Group in the development process, with the increase of development time, increasing liquid production, underground rock gradually loosening, a variety of siltstone, sand formation with the crude oil into the production system, not only wellhead platform equipment such as filters, outside Pump, pipeline and other damage and greatly reduce the quality of oil, a direct impact on economic efficiency. Through continuous experimental study of dynamic cyclone technology, combined with the characteristics of Wenchang Oilfield Group, the successful development of a unique dynamic cyclone desander, and Wenchang oilfield applications. Since January 1, 2012 operation, a total of sand 500Kg, sand removal rate reached 90%, the minimum size of sand reached 15μm.
