摘要
1999年大港油田在勘探中突破性地发现了千米桥潜山碳酸盐岩储集层凝析气藏，储集空间具有裂缝—孔隙双重介质特征，此类油气藏既是当前勘探的重点和难点，同时也是测井解释的一大难题。本文系统阐述以成像测井为代表的特殊测井系列在该气藏储集层评价中的具体应用。包括利用FMI（全井眼微电阻率成像测井）宏观拾取了储集层裂缝、溶孔；采取FMI与ARI（方位电阻率成像测井）相结合对裂缝延伸长度、溶孔有效性做了半定量一定量评价；应用DSI（偶极横波声波成像测井）判断了裂缝、溶孔的渗透性能；运用CMR（核磁共振测井）进行了储集层流体性质判别；以及采用Elanplus最优化模型组合技术求取了岩性剖面，并结合常规测井资料制定了有效厚度划分标准。上述方法综合测试成果表明，特殊测井系列的应用对千米桥潜山凝析气藏储集层的成功评价起到重要作用。图5表1（李建国摘）
Qianmiqiao buried hill condensate gas pool is an important discovery made in 1999's exploration in Dagang oil field. Lithology of the condensate gas reservoir is carbonate rock and the reservoir space is of fractureporosity type. This kind of reservoir is both the focus point and difficulty of exploration and a challenge to well logging interpretation at present. The paper presets the concrete application of special well logging program represented by imaging well logging to the carbonate rock reservoir evaluation for Qianmiqiao buried hill condensate gas reservoir. For instance, FMI (full hole microresistivity imaging) was used to macroscopically pick reservoir fracture and disolved pores; FMI in combination with ARI (Azimuth Resistivity Imaging ) were adopted to semiquantitatively to quantitatively appraise fracture extension length and dissolved pore effectiveness; DSI (Dipole Shear Sonic Imaging) was used to diagnose permeable charcteristics; CMR (Combine Magnetic Resonance Logging) was applied to discriminate reservoir fluid properties. Elanplus optimum model combined technology was adopted to acquire lithology profile; and effective thickness layering standards were established in association with conventional well logging data. Well test results showed that the application of special well logging program has played an important role in successful reservir evaluation of Qianmiqiao buried hill condensate gas reservoir.
