摘　　要：数据集成检索是油气勘探开发数据信息化的重要手段,然而现行方法检索效果并不理想,且查准率也低。提出了基于WebGIS技术的油气勘探开发数据集成检索方法,采用网络爬虫技术采集油气勘探开发数据,通过转换及标准化处理数据格式,建立数据索引,采用对数据语义特征提取和分析的方法,检索到与检索语义相似的油气勘探开发数据。实验证明:新的数据集成检索方法折扣累计收益值在9以上,查准率在95%以上,在油气勘探开发数据基础检索方面具有良好的应用前景。Data integration retrieval is an important means of information technology for oil and gas exploration and development data.However,the current method of retrieval is not ideal,the accuracy rate is low in practical application.A WebGIS based integrated retrieval method for oil and gas exploration and development data is proposed.Web crawler technology is used to collect oil and gas exploration and development data,through converting and standardizing the data format,a data index is established.The method of extracting and analyzing semantic features of the data is used to retrieve data with similar retrieval semantics.Experimental results show that the new data integration retrieval method has a discount cumulative profit value of over 9 and a accuracy rate of over 95%,which has good application prospects in the basic retrieval of oil and gas exploration and development data.
