摘要/Abstract

摘要： 高压平板阀是石油或天然气钻井、压裂、试油试气等作业中关键的井口采油气设备，高含砂井以及含砂量较大的施工作业，极易导致阀门开关受阻甚至密封失效。为适用高压高含砂作业工况的需求，对传统高压平板阀中的阀座结构进行优化，使阀门在原有基础上增加防砂功能，并运用试验研究的方法，对比分析高压平板阀传统阀座结构以及防砂阀座结构的防砂性能。结果表明，改进后的防砂阀座结构在压砂试验过程中，无砂砾进入阀体及阀座间隙，有效的切断了砂砾进入间隙的通道，开关卡阻现象得到了明显的改善；同时长时间的压砂试验，防砂阀座结构的阀门防砂性能无影响，依然能够保持良好的防砂功能。通过试验方式针对性的对两种典型结构进行分析，也为其他结构形式的高压平板阀的工程设计提供一定的参考。

Abstract:

High pressure gate valve is key wellhead oil and gas production equipment in oil or natural gas drilling, fracturing, well testing and other operations. In high sand wells and operations with large sand content, the valve switch is easily blocked or seal failure. In order to meet the requirements of high pressure and high sand content working conditions, the seat structure of the traditional high pressure gate valve is optimized to add sand control function on the original basis. The sand control performance of high pressure gate valve with traditional seat structure and sand control seat structure is compared and analyzed by means of experimental study. The results show that the improved sand proof seat structure has no gravel entering the body and seat clearance during the sand pressure test, which effectively cuts off the gravel entering the clearance channel, and the open /close jamming phenomenon has been significantly improved. At the same time, the sand control performance of the valve with the sand control seat structure has not been affected by the long time sand pressure test, and can still maintain good sand control function. The two typical structures are analyzed by means of test, which also provides some reference for the engineering design of other high pressure gate valves.
