海洋石油勘探面临钻井成本高、技术要求高,勘探风险高的难题,地震信息的应用在勘探过程中显得尤为重要.利用地震信息进行烃检也成为南海西部海域天然气勘探中的重要技术之一,但影响这一技术的因素很多,既有地质的因素、也有技术本身的原因,每一种都可能直接影响到这些技术能否有效地应用于油气勘探中.本文通过相关案例分析和正演模拟,对厚度、物性、含气饱和度等影响因素进行了深入的分析,并提出了相应的对策以及在实际生产中的具体应用方法.
The exploration of offshore oil is confronted with the problems of high drilling cost, high technical requirements and high exploration risk, and the application of seismic information is particularly important in the exploration process.Using seismic information for hydrocarbon sequestration also becomes one of the important technologies in the exploration of natural gas in the western South China Sea, However, there are many factors affecting this technology, both the geological factors, as well as the technology itself, each of which may directly affect whether these technologies can be effectively applied to oil and gas exploration.Through the relevant case studies and forward modeling, The influencing factors such as thickness, physical property, gas saturation and so on are analyzed in depth, and corresponding countermeasures are put forward as well as the specific application methods in actual production.
