埕岛油田中心一号平台是中石化胜利油田埕岛油田南部油区的集中处理平台,具有脱水、污水处理、注水、发电功能。于1995年投产,在2013年,对中心一号生产平台进行二次延寿评估时发现生产平台2#、3#钢桩承载力不能满足规范要求,存在桩基承载力不足的安全隐患。同时,对比2016年与2013年平台标高测量数据,发现该平台排除误差后3年内至少存在2.9~5.7cm的沉降量。为了有效监测平台沉降,并对短时间内发生快速沉降做出有效预警,平台业主在中心一生产平台四个固桩室桩腿上安装高精度静力水准仪(仪器标称精度0.1mm),实时监测平台桩腿沉降情况。
The No. 1 Platform of Chengdao Oilfield Center is the centralized treatment platform for the oilfield in the southern part of Chengdao Oilfield of Sinopec Shengli Oilfield. It has the functions of dehydration, sewage treatment, water injection and power generation. Put into operation in 1995, in 2013, the Center for the production platform for the second life extension assessment found that the production platform 2 #, 3 # steel pile capacity can not meet the requirements of the standard, there is insufficient security capacity of the pile foundation. At the same time, comparing the platform elevation measurement data of 2016 and 2013, it is found that the platform has at least 2.9 ~ 5.7cm settlement within 3 years after removing the error. In order to effectively monitor the settlement of the platform and make effective early warning of rapid settlement within a short period of time, the platform owner installs a high-precision static level (the accuracy of the instrument is 0.1mm) on the legs of the four pile-fixing chambers in the center of a production platform, Monitor platform leg settlement.
