The online monitoring of the partial discharge in the high switchgear is an important means of knowing the switchgear health status.8 high frequency pulse current sensor based on the roche coil were installed in the 35 kV switchgear at the waist station,and they were used in online monitoring of the partial discharge.Generally,the partial discharge in the switchgear does not lead to the insulation breakdown,but it can cause the local damage of the dielectric and the strength reducing of the insulation dielectric.

石油地震地质学的研究方法体系和研究流程吸引了石油界大量的学者和研究人员的关注,其在油气勘探开发的各个阶段都有了广泛的与应用,取得了良好的应用效果,并为其分支学科研究建设提供了纲要性的指导.作为石油地震地质学的分支学科,地震储层学中的"四步法研究方法对于非均质性强的复杂储层的表征和建模研究极具借鉴价值.
盆地东部跨越伊陕斜坡东部、伊盟隆起东部和晋西挠褶带北部，相对于盆地内部构造活动较强，以往研究显示地层的裂缝较为发育，储层渗透性较好.又处于上古生界生烃强度中心，气源岩条件优越，探井中含气显示好，普遍有天然气流产出.但区内已有勘探成果表明，该地区的储层厚度变薄，主要目的层山23、山22、山1、太原组尤其是山1、山22目的层的厚度一般仅为5-8m.给勘探工作带来了极大的挑战.以往的一些反演手段已经不能
准噶尔盆地车排子凸起南段油气资源丰富，目前较明显的构造型圈闭已经很难发现，勘探的主要目标也就集中在寻找岩性圈闭上，利用多种地震解释技术对车排子凸起南段的白垩系底部含油砂层进行了分析研究。首先利用测井分析和地质建模技术，认为白垩系底部发育多套砂体并向上倾方向尖灭；接着采用全三维解释发现了多个有利目标。采用多属性分析技术以及阻抗反演技术对发现的目标进行研究，发现使用多种技术发现的有利目标大体相同，钻井
