摘要
针对中国井下安全阀研究与发展不足的现状,首先,介绍了井下安全阀结构及分类方法,其次,分析了全球4大石油服务公司与国内企业的油管回收式产品,对比表明,国外不同井下安全阀公司的产品在结构和功能实现上各具特色,但很多核心技术却非常相似,能适用于不同的井深、温度及压力工况,而中国产品只能适合浅井低压环境。接着调研了国内外对井下安全阀一些研究最新情况,对比分析表明,国外研究主要集中在安全可靠性及功能多样化,而中国只能进行初步设计和室内外检测试验的现状。最后结合井下安全阀中国目前技术现状,提出了井下安全阀国产化的亟待解决关键技术以及解决方法与思路,对促进中国井下安全阀系统自主研发与生产具有重要意义。
Motivated by the insufficient research and development of subsurface safety valves in China, the structure and classification methods of subsurface safety valves are introduced, and oil tube recovery products from four global oil-service companies and domestic enterprises are analyzed. The comparison shows that foreign companies have characteristic structures and functions of subsurface safety valves but share similar core technologies. The products can adapt to different well depths,temperatures, and pressures; however, domestic products are only applicable for shallow wells and low-pressure environments.The latest research conditions of subsurface safety valves in both China and foreign countries are studied, and the comparative analysis shows that foreign research mainly focuses on the safe reliability and functional diversity, while domestic research only focuses on the preliminary design and either indoor or outdoor detection. Eventually, key technologies of the urgent settlement of the domestication of subsurface safety valves, as well as solutions and thoughts are proposed by considering the present technical state of subsurface safety valves in China.
