摘要
针对页岩气压裂评价中遇到的问题.介绍了当前用于压裂评价的随钻电阻率成像技术概况,探讨了该技术在地层评价和压裂分析中的应用.从不同侧面具体阐述了裂缝分析、构造分析、薄层分析、地应力分析、井眼轨迹分析等分析方式和研究成果.展示了应用随钻电阻率成像测量技术得到的裂缝特征和储集层相关的信息特征。鉴于国外知名的测井公司相继推出了各自的随钻电阻率成像测井工具及其配套技术.对此国内尚未见报道.建议不失时机地跟踪国外发展动态,开展该枝术的科研攻关。
In accordance with the issue encountered in shale gas fracturing evaluation,the author briefly introduced LWD resistivity imaging technology currently used in fracturing evaluation,discussed the application of the technology in formation evaluation and fracturing analysis,from different aspects,expounded the analysis methods and research results on fracture,structure,thin layer,earth stress and well course,and showed fracture features and information characteristics related to reservoirs obtained from LWD resistivity imaging technology.In view of the well-known foreign well logging companies have introduced their own LWD resistivity imaging tool and its supporting technology,there is no report about it in China,it is recommended to seize the opportunity to track abroad developments and carry out scientific research on this technology.
