摘要
新疆测井公司引进的阵列感应测井仪Excel2000相应的处理软件不完善,不能直接求取地层电阻率、冲洗带电阻率和侵入深度等。从而无法直接发挥阵列感应测井对地层真电阻率准确求解的优势。文章结合阵列感应测井曲线,从几何因子理论出发,在实验基础上分析该地区泥浆侵入特性,建立了针对准噶尔盆地的中低阻储层侵入模型。利用计算机反演技术,把模拟计算结果和现场测井响应相结合,最终确定出地层电阻率和钻井液侵入程度,取得了理想的效果。
The array induction logging instrument(HDIL) introduced by Xinjiang oil well logging company has not good explaining software. It could not get resistivity of stratum, resistivity of flushed zone and invasion depth of drilling fluid directly. Accordingly, it cannot give advantage play to solve resistivity of stratum by array induction logging instrument. In order to solve the disfigurement, this project establishes a mud invasion model to Junggar Basin′s middle or low resistivity reservoir bed which bases on array induction logging curve′s character, uses geometric factor theory and analyzes mud invasion character on experiment. We take computer reversion technique to combine simulate calculation results with scene logging respondence. At last, we get an ideal result of drilling fluid resistivity of stratum and invasion depth. This software is used to interpret a few LuLiang zone′s array induction logging data by XinJiang oil well logging company. The conclusion accords with testing for oil data. It gives advantage play to array induction logging, settles a good foundation to discern oil and water reservoir bed.
