南海西部海域地震信息烃检中常见的问题及其对策
|
摘要
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.
Offshore oil exploration and drilling costs faced by high technical requirements,high exploration risk problems,exploration seismic information in the process is very important.Seismic information for Hydrocarbon detection is an important natural gas exploration technology in the western South China Sea.Many factors affect this technology,both geological factors,but also technical reasons itself,Each of which may directly affect the effective application of this technology.We thorough analyzed the factors of thickness,physical properties and gas saturation,etc.,And put forward the corresponding countermeasures as well as specific application methods in practice.
