渤深4井区沙四段构造与储集层综合研究

渤深 4井区位于沾化凹陷最深的渤南洼陷带内 ,其深层沙四段具有充足的油气源条件 ,但因储集层埋藏深 ,地质情况复杂、地震资料品质较差等 ,致使前期对区内构造形态和储集层变化的规律认识不足。通过应用地震资料叠后目标处理、地震地质精细构造解释分析、多井约束三维地震反演等技术 ,对本区沙四段的复杂构造变化和储集层展布规律作了深入研究 ,进一步认识了本区地质构造和沉积变化的规律 ,为选择下一步勘探目标指明了方向。图 3参 2 (李建国摘 )

Integrated research of structure and reservoir for the Member S4 penetrated by Well Boshen-4

The Well Boshen 4 is located in the Bonan depression. Member S4 deposited very deep and got a very good oil-gas source. Because the reservoir beds are deep, the conditions of the geology are complex, and the quality of seismic data are poor, the former research on the geological structure and reservoir beds is not enough. In this paper, we adopt several types of effective technique, such as, poststack objective seismic processing, fine geological structure interpretation, well log constrained 3D seismic inversion, etc, and perform further research on the complicated geological structure and reservoir distribution of Member S4. Many research achievements and good geological effects are achieved.
