胜利滩海地区上第三系勘探技术——以垦东地区为例

The exploration techniques for Upper Tertiary System in Shengli beach area——a case history of Kendong area

以垦东地区的勘探开发为例,介绍胜利滩海地区上第三系勘探开发技术。该区上第三系为河流相沉积,是主要含油层系;油气藏类型主要有构造、构造—岩性和岩性类,其分布与构造带和储层发育情况有关。运用相干数据体和正交切线等方法落实断层延展方向及断裂系统组合问题;采取微构造成图方法有效地反映了起伏较小的低幅度构造;利用测井约束反演并配合地震多参数等技术精细描述了储层空间展布特征。在此基础上进行勘探开发一体化设计,实现了勘探和开发目标的最优化。

Taking the exploration and development of Kendong area as an example to introduce the exploration techniques for Upper Tertiary System in Shengli beach area. The Upper Tertiary System in the area is fluvial facies sedimentation which is the main oil-bearing serires. The distribution of reservoir types which include structural reservoir, structural-lithologic reservoir and lithologic reservoir depends on the development of structural belts and reservoir beds. The direction of faults and combination of fracture system were found out by coherent data volume and orthogonal line methods. Little amplitude tectonics were imaged by microtectonics imaging. The reservoir space through-goings were illustrated by logging constraint inversion together with other multiple seismic parameter. The integrated exploration and development targets were designed and optimized.
