乔文孝,阎树汶.用声波测井资料识别油气水层.测井技术,1997,21(3):215~220用电阻率评价孔隙流体往往受地层流体矿化度的影响,油层低阻、淡水层高阻以及盐水泥浆等造成电阻率解释困难。本文以Gassman方程、Berryman自洽理论为基础,研究了用声波测井资料和密度资料估算渗透层孔隙流体的弹性模量,进而评价油、气、水层的方法,成功地处理了20余口井的资料,取得了明显的效果,为低阻油气层和高阻水层等复杂地层评价增添了一种非电法的评价手段。
Pore fluids evaluation with resistivity (log) is often affected by salinity of formation fluids. And oil zones with low resistivity, freshwater zones with high resistivity as well as salt water mud make resistivity interpretation more difficult. Based on Gassmans equations and Berrymans self consistent theory, a technique is developed to estimate elastic moduli of pore fluids in permeable formations using acoustic well logging data and density logging data. It has been successfully used for data processing of more than 20 wells. The results prove it is good for identifying pore fluids (oil, gas and water) in permeable formations, especially for the formations saturated with high resistance water or low resistance oil.
