摘 要:位于中东地区某盆地内的Y油田M组碳酸盐岩储集层岩性复杂、隔夹层多、非均质性强,具有中低孔、低渗透、低电阻率、超高压的特征。由于储集层电阻率低、油水层电性差异小,且发育多套油水系统,以电阻率为主的常规测井方法很难准确判断储层流体性质。鉴于电阻率方法的局限性,引入并开展了基于电缆地层测试分析技术的流体性质判别方法研究,大量现场应用结果表明:以油、水密度差异为基础的压力梯度法和以油、水光谱差异为基础的光学流体性质分析技术能够较准确地判别流体性质,在中东地区Y油田复杂低阻碳酸盐岩油藏流体性质识别方面具有较好的应用效果。In M Formation of Y Oilfield in a basin of Middle East,lithology was complex with the characteristics of many interbedings,strong heterogeneity,low porosity and low permeability and low resistivity in the reservoirs.because of low resistivity in the reservoir,there existed small electric differences between oil and water layers and there developed several oil-water systems,it was difficult for determining the fluid type via conventional log data.In consideration of the limitation of method of resistivity,the method for identifying fluid property based on wireline formation testing was introduced and studied.The results of field application show that pressure gradient method based on the difference of fluid density and optical fluid analysis technique,the fluid spectrum can precisely distinguish the liquid type.It is used for identifying the fluid property of low resistivity reservoir in Y Oilfield in Middle East and better application result is obtained.
