摘要
随着勘探和开发进程的快速推进,哥伦比亚X区块已发现的"断背斜、断鼻"等构造圈闭已基本被查明和投入开发,能否寻找到岩性圈闭是关系到X区块油气勘探开发前景的关键性问题。但前期地震工作均围绕构造落实展开,导致了利用原有地震资料难以刻画岩性圈闭。为此,提出了基于地质目标的迭代式处理解释一体化技术,针对X区块储层特征建立处理和解释之间相互渗透、迭代递进的研究模式,开展岩性圈闭预测和目标评价工作。根据处理解释一体化研究成果部署的W4井获得高产工业油流,充分验证了迭代式处理解释一体化技术的有效性,同时为X区块下一步勘探开发部署开拓了新方向。
Following the rapid progress of exploration and production in block X of Columbia,the structural traps such as faulted anticlines and fault-nose structures have been identified and put into production.Discovery of lithologic traps now become the key issue concerning the prospect of oil and gas in block X of Columbia.However,previous seismic work was focused on structural targets,which caused great difficulties in lithologic traps characterization based on original seismic data.Therefore,the technique of iterative integration of seismic data processing & interpretation oriented to geological targets' was proposed.Based on the reservoir characteristics in block X,we performed lithologic traps prediction and targets evaluation by exploring the research mode of mutual penetration and iterative progress between seismic data processing & interpretation.According to the research result based on this technique,well W4 was deployed and recorded high-yield industrial oil flow,which verified the effectiveness of the technique and extended a new direction for future E&P deployment in this block.
