Prediction of thin "sweet spot" reservoirs in offshore areas and its application in Z Gas Field

  • 特低渗气藏的有效开发难度大,“甜点”预测及开发井位设计是低渗气藏有效开发的关键。使用梯度−90°相移技术对特低渗储集层进行了精细刻画,得到了砂体厚度图;在此基础上,通过微观和测井资料分析,明确“甜点”发育的类型及成因。在“甜点”发育模式的指导下,采用梯度波谷和属性定性识别孔隙型“甜点”发育区,采用最大似然属性和裂缝密度识别裂缝型“甜点”发育区。研究区H4层主要发育孔隙型“甜点”,平面上位于研究区北部和东部,纵向上位于H4b2和H4b3小层。H5层发育裂缝型和孔隙型“甜点”,平面上位于研究区南部,纵向上位于H5a3和H5a4小层。孔隙型“甜点”分布受控于有利沉积相带区,裂缝型“甜点”主要发育在靠近断裂附近和翼部构造强挤压区。基于“甜点”刻画结果,部署2口多底井,试验井大斜度段位于H5a层,水平段分支部署在H4b层,兼顾H4和H5“甜点”,实现特低渗气藏的有效开发。本研究方法对深层发育薄“甜点”的特低渗气藏“甜点”预测和开发方案编制具有参考意义。
