【摘要】 新疆TPT油田一间房组碳酸盐岩储层为缝洞型储层,其缝洞系统在纵、横向上具有较强的非均质性。识别和划分缝洞单元是提高勘探成功率的有效途径之一。本文首先根据钻井资料建立缝洞系统的理论地质模型,通过地震模型正演对各种常用的地震波动力学属性参数的缝洞响应特征进行了分析;在此基础上把多种地震波动力学属性参数融合成一种综合参数,结合钻井、测井和开发资料对目的层储层的缝洞单元进行了划分。据此建立了一套利用地震波场参数识别和划分碳酸盐岩储层缝洞单元的方法,可以用于后期的勘探和开发。更多还原

【Abstract】 The Yijianfang Formation carbonate reservoir in Xinjiang TPT Oilfield is fracture-cave type’s reservoir that has strong non-homogeneity in both lateral and vertical directions. Recognition and delimitation of fracture and cave units are one of effective ways improving successful rate of exploration. First,the paper created theoretical geologic model of fracture and cave system based on drilling data and analyzed the response of fracture and cave on various common dynamic attribute parameters of seismic waves by seismic forward models; then,the multiple dynamic attribute parameters of seismic waves were integrated into an integrative parameter on that basis and delimitation of fracture and cave units of objective reservoir was carried out by combination with drilling,logging and developing data. The method using seismic wavefield parameters for recognition and delimitation of fracture and cave units of carbonate reservoir was created accordingly,which is able to be used for latter exploration and development.更多还原
