摘要
随着勘探开发的进一步深入,裂缝性油气藏在整个油气新增储量中所占的比重愈来愈大,对储层裂缝分布规律与发育特征的正确认识决定裂缝性储层勘探开发能否成功。在进行大量文献调研的基础上,对地质、测井、地震和裂缝建模及构造应力场等裂缝识别预测方法进行了系统整理和比较,指出其存在的问题,并提出了改进方法。基于预测方法的原理提出了每种方法适合的裂缝成因和类型,并指出单一方法和技术不能满足勘探开发的需要,必须将各种预测方法手段综合应用以达到精细预测的目的。初步认为,DFN裂缝地质建模方法是将来重要的发展方向。
As exploration and development is proceeding further,the share of fractured oil & gas reservoirs in the overall newly incremenlal production of oil & gas is getting greater increasingly.The successful exploration and development of a fractured reservoir depend on the correct utulerstanding of fracture distribution in reservoir and the fracture developing features.Based on investigation of significant literatures,methods for fracture identification and prediction are storied and compared systematically,covering geology,logging,seismic and fracture modeling as well as tectonic stress field,existing problems are pointed out and updating methods are proposed.Genesis and type of fracture suitable for each method are proposed based on the principle of prediction method.Also,it is pointed out that individual method and technology can not meet the needs for exploralion and development and the integral application of various prediction methods can deliver a detailed prediction.It is preliminarily suggested that DFN fracture geologically modeling is the important direction for future development.
