摘要
进口的RTTS液压循环阀满足不了生产的需要,研制出一种新型液压循环阀,具有结构简单、保养维修方便、施工成功率高的特点。实现了产品的国产化,降低了生产成本和施工费用,特别适用于无硫化氢油井的压力测试工艺。
Since RTTS for the import of hydraulic Valve cycle of production can not satisfy the needs of developed a new hydraulic valve cycle is developed. The tool is simple in structure, easy in maintenance, high success rate in construction, thus it is possible to be made in China and suitable to be used in the well with non-Sulfured hydrogen.
