在勘探阶段,准确地识别贯穿盆地的断裂系统并分析它们对有利区带的影响是研究的焦点.在评价、开发和生产阶段,随着对油藏的不断认识,需要对局部范围内的断裂系统进一步加深认识,不同的是这时需要关注的是由完全不同方向的构造应力形成的断层和断层系列,因为它们影响或将要影响最终的采收率.常规的断裂系统解释一般根据断裂系统在地震剖面上的特征进行人工观察、识别,经三维地震资料处理得到.通过一种先进的优化算法--蚂蚁追踪技术,可以很好地表现出断层、裂缝系统的空间分布.相对于肉眼只能识别出少量十分明显的断层和裂缝,蚂蚁追踪断裂的自动解释结果不仅是地震剖面上断层、裂缝系统的客观反映,而且较人工的解释结果更加清晰、直观和准确.基于Petrel软件该技术在任丘潜山雾迷山组油藏断裂系统分析中取得了良好的效果,认为该技术可以用在本区剩余油预测中,并具有较好的推广价值.

At the stage of exploration,the focus should be placed on correct identification of the tectonic structural fault system crossing the basin and the influence on the favorable areas.During the process of evaluation,exploitation and production,as deepening the understanding of reservoirs,the structural fault system in local area should be well understood,the difference is that at this time,what should be cared is the faults and fault system formed by totally different tectonic stress orientation,because they will impact the final recovery.Common fault system interpretation is achieved according to the characteristics of the fault system on seismic profile through artificial observation,identification and 3 D seismic data process.At the present,an advanced optimized algorithm,i.e.,ant tracking technology,can well exhibit the spatial distribution of fault and fracture system.Compared with naked eye by which,only little faults and fractures can be recognized,the automatic interpretation result by ant tracking technology can well reflect fault and fracture system on seismic profile,but also,the result is more clear,visual and precise.The technology based on Petrel Software is applied in fault system analysis for Wumishan Formation of Renqiu buried hill reservoir and good consequence achieved.It is pointed out that the technology can be used in the prediction of remaining oil distribution and is worthy of popularization.
