| 摘 要： | 孔、洞、缝三重介质油藏在碳酸盐岩储层中较为普遍。采用Warrant-Root的方法建立了三重介质油藏水平井渗流数学模型,并采用Lord Kelvin点源解、贝塞尔函数积分和泊松叠加公式等方法求解了各向异性无限大三重介质油藏水平井在拉氏空间中的无因次压力响应函数。通过计算得到了无因次压力和压力导数双对数理论图版,并在其基础上分析了三重介质油藏水平井渗流特征及其影响因素。

| Abstract: | Triplemedium reservoir which include Matrix, cavern and fracture were very common in carbonatite reservoir bed. In this articlewe use Warrant otmathematic modal to establish the mathematicmodal for flow in porousmedia of triplemedium reservoir. We used such theory as Lord Kelvin point source soluion, integral property of Bessel function, poisson′summation ormula to obtain the dimensionless pressure ofhorizontalwell in triplemedium reservoir in laplace domain. We obtained the type curve ofdimensionless pressure response in bottom hole. Andwe also have analyzed the influence of those factors to pressure response ofhorizontalwell in triplemedium reservoir. |
