陈家洼陷沙三中亚段精细构造解释及储层评价

Fine structural interpretation and reservoir evaluation of sub-central member of Sha 3, Chenjia depression

针对陈家洼陷沙三中亚段浊积岩储层的分布及其在成藏上与构造的配置关系 ,以三维可视化技术和多元储层参数反演技术为主要手段 ,开展了全三维构造解释和储层预测及描述等系列研究。通过研究 ,重点明确了该区沙三中浊积岩储层空间上的分布和沉积特征 ,认为在具备良好构造条件的前提下 ,该区油气分布主要受储层发育状况的控制。通过本次工作得出结论 :三维可视化技术和多元储层参数反演技术是目前较突出的两项地震技术 ,其在实际应用中能更加突出地质效果 ,因此在今后勘探综合研究中将发挥重要作用 。

With 3D visualization and multi component reservoir parameter inversion as the main measures, full 3D structural interpretation, reservoir prediction and description are performed with a view to the distribution characteristics of the turbidite reservoir of Sha3 central member and its configuration relationship between structures and reservoir forming in Chenjia depression. Space distribution and sedimentary features of Sha3 turbidite reservoir space in this area are understood and oil/gas distribution in same region is mainly controlled by reservoir development when ideal structures exist. Exploration drilling demonstrates 3D visualization and multi component reservoir parameters inversion are two outstanding seismic technologies and should be applied widely in future exploration research to achieve better results.
