【摘要】 随着中东AD油田油气勘探的不断深入,尤其是进入开发阶段,对与裂缝有关的高产带的预测精度要求越来越高。常规裂缝预测受各种客观因素影响,精度很难再有大的改善。"蚂蚁追踪"算法建立了一种突出断裂面特征的断层和裂缝解释技术,在地震体目的层段中设定大量的电子"蚂蚁",这种电子"蚂蚁"可以根据不同的信息素追踪出微断层或裂缝。利用"蚂蚁追踪"算法,不但有效地提高了AD油田主要目的层K层的裂缝预测精度,拓展了裂缝预测的思路,而且大大缩减了人工解释时间,为油田高产带预测和开发建模提供了重要依据。更多还原

【Abstract】 With the continuous deepening of exploration of AD Oilfield in the Middle East especially when it entered into the development stage,precision for the prediction of high-producing zones was higher and higher.It was difficult to improve the fracture prediction precision with the conventional fracture-prediction techniques which were easily influenced by many objective factors.A new fracture interpretation technique was established based on "ant tracking" algorithm.Large quantity of electronic ants set in the target layer of the seismic volume previously could track small faults or fractures on the basis of different information element.The "ant tracking" technique is applied,a higher precision of fracture prediction within a shorter time is obtained for K Reservoir in AD Oilfield,therefore a new fracture prediction idea is expanded and time of manual interpretation is reduced.It provides an important basis for the high-producing zone prediction and the development modeling of the AD Oilfield.更多还原
