摘要
基岩是未来吉林油田深层领域的主战场,储集空间主要为构造裂缝。通过科研实践和实际生产对比发现,采用一种方法或单一学科来研究裂缝发育情况已经不能满足勘探需求。以梨树断陷怀德基岩为研究区域,采用平衡剖面法恢复构造演化史,分析断层及裂缝走向;多属性融合方法划分岩性带;井震联合确定裂缝发育优势岩性。从宏观到微观,综合利用地质、地震、测井资料,开展构造运动和岩性质控下的基岩储层裂缝预测方法及应用研究。提出的方法技术流程在实际应用中取得了较好的效果,为研究区的基岩储层预测研究提供了科学依据。
Fractures are developed in many exploration and development areas in the Jilin exploration area.In terms of deep exploration,the bedrock will be the main battlefield for the deep areas of the Jilin Oilfield in the future.Through the comparison of scientific research practice and actual production,it was found that the use of one method or a single discipline to study fracture development can no longer meet the exploration needs.Taking the Huaide bedrock in the Lishu Fault-depression as the research area,the balanced section method was used to reconstruct the tectonic evolution history,and the strikes of faults and fractures were analyzed.The multi-attribute fusion method was used to divide the lithology zone,and the well seismic combination determined the dominant lithology of fracture development.From macro to micro,through the comprehensive utilization of geological,seismic and logging data,it was carried out the research on fracture prediction method and application of bedrock reservoir under tectonic movement and lithology quality control.The proposed method and technical process have achieved good results in practical application,which provides a scientific basis for the prediction of bedrock reservoir in the study area.
