普光东北部须家河组储层反演技术及应用
|
Abstract:
普光地区具有良好的勘探潜力,但目前缺少对于陆相有效储层的勘探。本次研究将叠后和叠前确定性反演相结合,详细阐述了研究区有效储层特征。研究结果表明,须家河组砂体在反演中显示效果较好,须六段以高纵波阻抗特征为主,须四段以低VP/VS (纵横波速度比)特征为主,须二段砂体厚度较大,呈现出较好的反演效果。通过反演结果可知,研究区须家河组具有良好的勘探潜力,并对后期油气开发具有指导意义。
The Puguang area has good exploration potential, but there is a lack of exploration for continental effective reservoirs. In this study, the post-stack and pre-stack deterministic inversion were combined to elaborate the characteristics of the effective reservoir in the study area. The results show that the sand body of the Xujiahe Formation shows good results in the inversion, with the high longitudinal wave impedance characteristics of the Xu6 Member, the low VPVS characteristics of the Xu4 Member, and the thickness of the Xu2 Member sand body is larger, showing a good inversion effect. Through the inversion results, it can be seen that the Xujiahe Formation in the study area has good exploration potential and has guiding significance for the later oil and gas development.
