用聚类分析法确定土壤腐蚀试验埋点位置

ARRANGEMENT OF DISPOSAL SITES FOR SOIL CORROSTION TEST BY USE OF CLUSTER ANALYSIS

在大港油田的土壤腐蚀性调查方案设计中采用聚类分析方法确定试验埋点的布置，使得腐蚀试验所需的埋设点数量减少到只是原计划的１／４左右．这种布点方法可摒弃原候选点之间的冗余信息，从而使试验点的数量减少而整个试验所提供的信息并不丢失．

AbstractThe arrangement of disposal sites is an important consideration for in-situ soil corrosion tests. In the present paper, the mathematical principle of the arrangement is discussed and various cluster analysis methods are introduced for this purpose. These new methods had been successfully applied to the soil corrosivity survey of Da-Gang Oil Field areas. As a result, the amount of the disposal sites for corrosion test could be reduced to a quarter of that for the originally suggested conventional arrangement. The ie8S test sites chosen could provide the most necessary corrosion information, since only the redundant sites were abandoned.
