不依赖径向流直线段的试井分析方法研究

Study on the Well Test Analysis Method for the Well without Radial Flow.

试井技术与试井结果已经成为油藏描述和正确合理开发油田的重要手段 ,但不出现径向流的测压资料给油田的试井分析工作及地层压力计算带来了诸多的不便。在研究前人理论的基础上 ,详细研究了不出现径向流直线段的试井分析方法 ,较好地解决了由于低渗透、井间干扰。

Well test technology is one important means for the reservoir description and development.For the test data without radial flow,the are many difficulties to analyze and determine the formation pressure.Based on the prevenient research work,one new method is developed to analyze the test data without radial flow.It can be used to solve the problem for the low permeability reservoir,the pulse test and the multilayer effects.
