铀尾矿库的WSN安全监控监测技术是一门新型领域技术,是实现铀尾矿库安全综合治理的重要前提,定位技术因其能够快速定位事件发生区域的地理位置而成为WSN的关键技术之一。RSSI测距定位技术因其易于实现、成本低等特点而被广泛应用,然而其在铀尾矿库中会受到多径、非视距等因素的影响,远距离得到的RSSI值测距误差较大。为此,提出一种镜像最小通信圆约束域定位算法,未知节点利用多个近距离RSSI测距值生成最小通信圆,以锚节点坐标镜像最小通信圆生成镜像圆,多条件约束形成定位区域进行区域定位。仿真结果表明:多最小通信圆定位效果优于单最小通信圆,且比传统RSSI和RSSI质心算法具有更高的定位精度和...

The analysis of oil sources shows that the crude oil of the lower members of Guantao Formation in southwest Gudao Oilfield are mainly from the source rock of Sha-3 member in Gunan sag. The pool types of oil reservior are mainly structure reservior. The main controlling factor of the formation of southwest Gudao Oilfield reservoir is the fault sealing ability. The study on fault sealing ability indicates that the fault sealing of Lower-member 7-8 Guantao Formation is good and is favorable for the formation of reservoirs. While the fault sealing of Lower- member 9-11 Guantao Formation is bad and...
