2008年中国石油川庆钻探工程有限公司测井公司从俄罗斯引进了两套H-IKZ-2型感应测井仪,为了配合该仪器在川渝地区碎屑岩的推广应用,本文对其测井资料与Atlas公司阵列感应进行对比分析研究,发现俄罗斯感应在薄层段其深浅电阻率不相匹配。对俄罗斯HIL感应的四个探头16条原始测量曲线合成4条探测深度由浅到深的电阻率视值曲线进行井眼校正、趋肤校正,对4条校正后的电阻率曲线进行分辨率提高和匹配处理得到四条纵向分辨率匹配的电阻率曲线,从而解决了俄罗斯感应在薄层深浅电阻率不相匹配问题。并能计算出三种不同分辨率的电阻率曲线,处理出的俄罗斯感应测井曲线基本上与Atlas公司5700阵列感应一致,满足了实际生产需要,从而使俄罗斯HIL感应能在川渝碎屑岩测井中推广。最后文章以实例的形式分析了孔隙度、渗透率等储层参数对俄罗斯感应测井的影响,分析了应用效果,总结出了定性、定量解释川中碎屑岩储层的方法。
In 2008, CNPC Chuanqing Drilling Engineering Co., Ltd. logging company imported two sets of H-IKZ-2 induction logging tools from Russia. In order to cooperate with the popularization and application of this instrument in the clastic rocks in Sichuan and Chongqing, Data and Atlas array induction conducted a comparative analysis of research and found that the Russian sensor in the depth of thin-layer resistivity does not match. For the four probes of HIL sensing in Russia, 16 original measurement curves were synthesized and four detection depths were drilled from the shallow to the deep resistivity profile for borehole correction and skin correction. The resolution of the four corrected resistivity curves was improved and Matching process obtained four vertical resolution matching resistivity curve, thus solving the Russian induction in the depth of thin layer resistivity does not match the problem. And can calculate the resistivity curve of three different resolutions. The processed Russian induction logging curve is basically consistent with the Atlas 5700 array induction to meet the actual production needs, so that the Russian HIL induction can be made in Sichuan-Chongqing clastic rocks Logging in the promotion. Finally, the paper analyzes the influence of reservoir parameters, such as porosity and permeability, on the induction logging in Russia in the form of an example. The application effect is analyzed and the method for qualitatively and quantitatively interpreting the clastic reservoirs in central Sichuan Basin is summarized.
