夏子街油田属低渗透带气顶的断块饱和油藏，由于构造及油气水关系复杂，给生产井压力恢复曲线解释带来了很大的困难，以致不能准确地掌握地下油气水运动规律及油气藏的动态变化。为此，以常规试井分析方法为基础，依据双孔介质油气藏渗流理论，提出了具有复杂内外边界条件的双孔介质油气藏典型试井曲线的识别方法。对早期压力曲线出现的“驼峰”及不呈45°直线的问题，进行了分析验证，解决了此类油田长期存在的试井分析难题，为认识改造油气藏提供了可靠的依据。
Xiazijie oilfield is a fault-saturated oil reservoir with low permeability and gas cap. Due to the complex structure and the complicated relationship between oil and gas, it is very difficult to interpret the pressure recovery curve in production wells. As a result, it is impossible to accurately grasp the movement rules of underground oil- Dynamic changes of oil and gas reservoirs. Therefore, based on the conventional well test analysis method and based on the seepage theory of two-porosity media reservoirs, a typical well testing curve identification method for two-porosity media reservoirs with complicated internal and external boundary conditions is proposed. The “hump” and the non-45 ° straight line problems appearing in the early pressure curve were analyzed and verified to solve the long-standing well test analysis problems in such oilfields and provided a reliable basis for understanding the reforming of oil and gas reservoirs.
