在低渗透油田的生产开发中,压裂的完井工艺是提高油田单井产能的有效增产手段。由于高压注水、持续性注水造成的油田内部原生及压裂次生的裂缝不规律地开启、闭合,致使油井方向形成快速水淹,会对油田产量产生影响。试井通过油水井的单井工况短时调整造成的单井压力、产量变化得出油水井间的连通关系。总结了低渗透油田注水动态裂缝的成因,采用试井方式定量评价油水井间连通关系,通过优化注水井不稳定注水工作制度,控制油水井间裂缝连通,提高注水波及体积,改善注水开发效果。

研究GIS外壳的振动特性对于保证设备的稳定运行具有重要意义。文中围绕GIS隔离开关、盆式绝缘子两种故障类型进行外壳振动特性的仿真分析,搭建了盆式绝缘子完好时隔离开关触头接触不良和隔离开关正常时绝缘子含有裂纹时的仿真模型,利用有限元仿真软件计算了接触状态不同时隔离开关的振动加速度以及不同裂纹深度时盆式绝缘子的模态频率与振型。研究表明:隔离开关出现接触缺陷后,触头接触面积越小,对导体施加电流越大,隔离开关的振动加速度就越大。当盆式绝缘子出现裂纹缺陷时,GIS外壳模态频率随着裂纹深度的不断增大而逐渐下降。因此,
