| 摘 要： | 以准噶尔盆地石炭系火成岩油藏为研究对象，从油藏地质特点和测井特征出发，利用取心资料和常规测井数据，研究该区火成岩裂缝的成因及特点。采用M-N交会图对火成岩岩性进行识别;在考虑裂缝对孔渗影响的基础上，提出了裂缝各种弹性参数的计算方法;结合电成像测井资料、试油资料以及岩心描述,构建了该区火成岩裂缝储层测井综合评价方法。研究发现,裂缝在弹性参数上表现为低杨氏模量和高泊松比特征。该方法能够较好地满足利用测井资料对该地区火成岩裂缝性油藏进行研究的需要。 |

| Abstract: | Taking the Carboniferous igneous reservoirs of Junggar Basin as an example,the authors examine the origin and characteristics of fractures in the igneous rocks by using reservoir geology,core data and conventional log data.Lithology of the igneous rocks are identified by M-N cross plot.Taking the impact of fractures on porosity and permeability into consideration,we put forward methods for calculating elastic parameters of fractures.In combination with imaging log data,formation testing data and core descri... |
