| 摘 要： | 以无限空间点源压力响应的基本解为基础，研究了水平方向无限大油藏在任意位置的压力响应，从测压点位置、等价压力点、多解性的解决办法等方面探讨了水平分支井的试井解释方法。以渤海油田4个分支井眼的水平分支井SZ361CF1为例，系统研究了非均质双重介质油藏中瞬时压力响应的有效算法、在无限导流能力的井内等价压力点的取法、以及严重存在多解情形的试井解释方法等。对油田提高油藏采收率、增产具有重要意义。 |

| Abstract: | Based on the basic solutions of the pressure response of point source in infinite space, pressure responses at any point in a horizontally infinite reservoir are studied. Furthermore, methods of welltest interpretation are researched in aspects of observation points, equivalent pressure point and treatment for multisolutions of pressure response. An example of horizontal multilateral well with 4 branches is given as Well SZ361CF1 in Bohai Oilfield, the authors systematically study the efficient algorithm about transient pressure response in heterogeneous reservoirs with dual porosity, the calculation of equivalent pressure points in a well hole with infinite conductivity, the welltest interpretation method with serious solvability, etc. The achievement is of great importance to EOR and stimulation measures. |
| Keywords: | horizontal multilateral well transient pressure equivalent pressure point conductivity model well test |
