基于数据驱动的压裂施工异常中断自动恢复方法及系统

本发明公开了一种基于数据驱动的压裂施工异常中断自动恢复方法及系统，该方法通过构建历史工况数据集并利用共享时序编码器进行深层表征与聚类，提取各类工况对应的历史最优恢复参数；在实时恢复阶段，通过智能匹配获取当前工况下的恢复起始砂比、砂比提升步长及井筒容积倍数，并基于多砂型独立阶梯恢复算法，按粒径顺序对各支撑剂类型分别进行阶梯递进式阶段生成与拼接，形成完整的恢复泵注计划后下发执行。本发明实现了异常恢复过程从人工经验决策向数据驱动智能决策的转变，有效提升了恢复参数的科学性和恢复过程的平稳性，具备持续学习优化能力，适用于各类压裂施工异常中断后的自动恢复场景。

一种大通径手动平板闸阀

本发明公开了一种大通径手动平板闸阀，属于阀门技术领域，包括阀本体、旁支路管、阀腔、闸板、驱动杆及拧转组件。阀本体开设有通口，两侧分别设有进入端和输出端；旁支路管连通设置于进入端与输出端之间，其上安装有针型阀；闸板滑动设于阀腔内并开设有阀口；驱动杆通过自润滑衬套螺纹穿设于闸板上；拧转组件设于阀本体外端且与驱动杆传动连接，包括直径依次增大的三级啮合齿轮，手轮旋转较小角度即可驱动驱动杆快速旋转以切换阀口与通口的连通或切断。本发明通过旁支路管平衡压差降低扭矩、通过三级齿轮增速传动缩短操作时间、通过自润滑衬套防止长期不动作导致的锈蚀卡滞，具有启闭省力、操作快速、可靠性高的优点。
