摘要
兴城地区火山岩裂缝是深层天然气重要储集空间,主要类型为低角度缝、高角度缝、网状缝、应力释放缝、重泥浆压裂缝和机械破碎裂缝,火山岩裂缝的测井识别是个难点。本文通过对目前区内已经钻探井的火山岩裂缝进行归类,对其测井资料的响应特点进行分析,从而对火山岩裂缝的测井响应特征进行定性分析和描述,对6种典型的裂缝进行了归纳总结。
Volcanic rock fracture is the important deep zone natural gas reservoir space in the Xingcheng district. Main fractures are low angle fracture, high angle fracture, reticular fracture, stress free fracture, heavy mud fracture and volcanic rock fracture. It is known that the identification of volcanic rock fracture is difficult by logging identification of fracture. The loggings informations response characteristics are classified and analyzed by well drilling information in this district. In this way, the loggings information of volcanic rock fracture is analyzed qualitatively and described. Furthermore, six kinds of typical volcanic rock fractures are summed up.
