Madong 2 well area is characterized by a geological form of source side-unconformity-slope.In this paper,the Permian unconformity surface in Madong 2 Slope is recognize by seismic,geological and well-logging data;and then,a pattern of stratigraphic structure is established in terms of unconformity surface;the discovered oil reservoirs are restudied based on the pattern;and the association of source rock,reservoir and caprock is also analyzed;and the relationship between unconformity source and reservoir forming is discussed.Results show that(1) there are five stages and two types of unconformity surfaces for the Permian;(2) the surfaces control not only the stratigraphic structure,contact relationship,distribution and trap type but also the hydrocarbon migration and accumulation;(3) oil reservoir in Madong 2 well area is a stratigraphic overlap one,with a reservoir-forming pattern of side source-unconformity-slope.

Google-Earth(谷歌地球)是GoogleTM公司在全球推出的一款提供三维卫星影像和矢量地图服务的免费软件,通过它能查看油田辖区的高清卫星影像并采集地面目标物的基础地理信息,为我们实施油田的地理信息数字化管理提供了"实景地图"这一直观、先进的科技手段。我们利用它进行了油田地理信息的桌面化详查和采集、对选定目标物进行标注和测量、绘制油田周边地理信息基础图件、叠加油田航拍影像后实现辖区高清航拍地图调阅和测量、野外作业实施即时导航、优化辖区边探井的巡检管理和环境评估等方面的应用,取得了较好的效果。

准噶尔盆地有很多边探井位于已开发油区外围的戈壁荒漠中,由于诸多原因,使这些边探井日常管理十分不便。Google-Earth是一款著名的桌面三维卫星地图服务软件。借助Google-Earth的三维卫星影像和矢量地图服务,对边探井实施精确定位,查清所有边探井的位置及其周边环境状况,可优化出便捷的巡井线路,对边探井井场及周边环境进行评估、监测,提高边探井管理效率。

与传统机械压力计相比,电子压力计具有记录数据精度高,工作时间长等显著优点.在生产实践中,形成了适合克拉玛依油田的电子压力计试井工艺技术,并在克拉玛依油田的探井油藏评价中有着广泛的应用,为油田勘探开发提供了大量宝贵的地层参数.
