AN EVALUATION SYSTEM FOR OFFSHORE OIL & GAS GEOCHEMICAL SURVEY
-
摘要: 参考"石油天然气地球化学勘查技术规范"数据处理、异常评价与解释的要求,充分应用地理信息系统(GIS)可视化技术、空间分析功能、图层叠置功能,智能计算出海域油气化探异常系数,包括异常强度、异常面积、异常衬度、异常点数等指标。结合相关地质条件,耦合了神经网络、模式识别等数学模型,开发了具有自主知识产权的海域油气化探综合评价软件,并将该软件应用于实际工作中,取得了较好的效果。Abstract: With reference to the request of "specifications for oil & gas geochemical survey" in data processing and anomaly assessment, a software is developed to fully use the visualization technology, spatial analysis and superimposed layers based on Geographical Information System (GIS) and calculation of correlative coefficient of geochemical anomalies, including abnormal strength coefficient, abnormal area coefficient, abnormal background coefficient, abnormal points coefficient and so on for oil and gas geochemical exploration.The software has been successfully applied to Yingge Sea Basin and South Yellow Sea Basin.
