官东高成熟探区中浅层精细勘探
|
摘要
官东地区为大港油田的高成熟探区之一 ,2 0 0 0年以来开展精细勘探取得了显著成效 ,发现了千万吨级的优质储量区块。精细勘探中主要采取以下措施 :关注动态信息及时分析研究 ,地震与地质紧密结合解决关键地质问题 ,采用多种技术(地层精细对比 ,高精度目标处理 ,构造精细解释 ,储集层预测 ,油藏研究等 )加强综合研究 ,优化部署方案 ,降低勘探风险。官东地区的勘探实践说明 ,随着科技水平的提高 ,高成熟探区仍然具有巨大的勘探潜力。图 3(刘子藏摘 )
It is difficult to prospect for shallow and middle reservoirs at late exploration stage in Guandong area. Since 2000, the block was studied again, some best exploration achievements were made and a high-quality reserve block of ten million tons was found. This breakthrough was made because of followings:(1)timely analyzing the exploration and production information; (2)perfectly integrating seismic and geological studies; (3)applying multiple technologies, such as precise strata correlation, precise structural interpretation, precise trap identification, applying advanced technical methods in reservoir prediction; and (4)optimizing deployment programs and reducing exploration risk. The successful exploration experience in Guangdong block suggests that with the improvement of the science and technology level this highly explored block still has a big potential of petroleum exploration.
