If the project proceeds as planned , toxic oil will move from offshore platforms through an earthquake zone and down and 800 - kilometer pipeline that crosses 24 active seismic faults and more than 200 wild salmon spawning rivers and tributaries 如果该项目顺利进行，有毒的油气将通过一个地震带从海上平台泄露出来，同时一条800公里长的管线将穿越24个地震多发带，超过200条河流及其支流，而这正是野生大马哈鱼的产卵地。
The data processing system is designed to ensure the successful penetration and emplacement of offshore bucket foundation platform , can monitor in real time the offshore platform contruction process , analyse and process the penetration data , and exest an intelligent control over the suction penetration process according to the bucket foundation platform conditions 该数据分析处理系统是为保证海上桶形基础平台现场施工能顺利沉贯到位而研制，可对海上平台现场施工过程进行实时监测，对沉贯数据进行快速分析、处理，并根据桶形基础平台状态对负压沉贯过程进行智能控制。
The thesis is the initial research content of the project " bucket foundation and unstability mechanism research influenced by bucket foundation on silty . sand seabed " , which is supported by the national natural science fund . it mainly carry about the research of seepage gradient in the process of suction penetration and unstability mechanism of silty sand in the bucket foundation , and it also discuss and analyze the penetration effect of bucket foundation of the different ratio size 本文是国家自然科学基金项目“海上平台桶形基础及其作用下的粉质土海床失稳机制的研究”的前期研究内容，主要通过模型试验对负压沉贯过程的渗流梯度及其桶内粉质土的失稳机制进行研究，并探讨和分析了不同比尺的桶基的沉贯效应。
It faces three big cbai1enge to implement polymer flooding in an offshore oilfield : ( 1 ) it is lace of fresh water which leads to conventional polymer could not be used ; ( 2 ) the surface of platform limits the application scale ; ( 3 ) it is hard to adjust the well pattern , the well spacing and the well completion for the optimized application requirements 在海上油田实施聚合物驱技术面临三大挑战：缺乏淡水资源，常规聚合物不能满足要求；海上平台空间有限，对注聚设备有特殊要求；井网、井距和层系调整困难。
