摘要
基于蚂蚁算法的蚂蚁追踪技术是近几年发展起来的一种先进的优化算法,主要用于断裂系统自动解释技术,能够通过自定义相关参数,对目标区满足要求的大断层、小断层进行精细刻画和定量描述。在番禺30-1气田开发井的随钻过程中,应用该技术识别出了地震体和方差体中难以辨认的小断层和裂缝,分析了导致水平井钻井过程中漏失的原因,并描述了小断层、裂缝的特征,据此为钻井风险的预判提供了依据。以及为后续水平井位的优化提供有价值的参考。实钻结果证实,井位优化效果很好,充分满足了预期的设计要求。
Ant-tracking technique based on ant-tracking algorithm is a kind of modern optimization algorithm which is developed in recent years. It is mainly applied to automatically interpret faults system, and faults in target area can be finely and measurable described by setting some relative parameters. In PY30-1 gas field drilling period, using anttracking can identify some small faults and fractures which are hard to be figured out in seismic volume and seismic varince volume. By analyzing the reason of mud leaking which happened in horizontal well drilling and describing the character of fault and fracture, the supporting evidence is provided for evaluation of drilling risk and valuable reference to well -placement optimization. The method works well in actual drilling and fully meet the expectation of design.
