摘要:
为求取裂缝性储层关键参数,应用自然伽玛、声波时差和电阻率等测井曲线建立岩性解释模型的方法,求取岩性综合系数,发现岩性综合系数与泥质体积含量成反比,与白云岩体积含量成正比,用来识别岩性; 应用阵列声波测井能量衰减幅度、井径曲线、岩性综合系数等参数建立裂缝解释模型的方法,求取裂缝综合系数(F),F<0.36,裂缝不发育,0.36≤F<0.6,裂缝发育一般,0.6≤F<0.8,裂缝较发育,F≥0.8,裂缝发育; 最后综合分析岩性、裂缝综合系数,并结合基质解释参数,识别出油层、差油层、水层和干层。结果表明:裂缝综合系数大于0.48,岩性综合系数大于0.34,为油层; 差油层的特征为裂缝综合系数大于0.36,岩性综合系数大于0.24; 裂缝综合系数小于0.36,裂缝不发育,为干层; 水层特征主要为深侧向电阻率小于浅侧向。裂缝发育程度决定了青西油田储层含油性,即使岩性为白云质泥岩,只要裂缝发育,就可能存在油层。
Abstract:
To obtain the key parameters of fracture reservoir,such logging curves were adopted as GR,AC and RD et al to establish lithological interpretation model,and then to obtain the comprehensive lithology coefficient.It has been found that comprehensive lithology coefficient is inversely proportional to the shale volume content,directly proportional to the dolomite volume content,which can be used to determine lithology.The fracture interpretation model was established to study the fracture interpretation model using the parameters such as energy attenuation amplitude of DAC,CAL and comprehensive lithology coefficient(F).If F <0.36,the fracture is not developed; if 0.36≤F<6,the fracture is generally developed; if 0.6≤F<0.8, the fracture is relatively developed; if F≥0.8,the fracture is developed.A comprehensive analysis of lithology and fracture comprehensive coefficient,combined with matrix interpretation parameters has been made with the result that oil layer,poor layer,water layer
