摘要
曙 10 3井是曙光古潜山构造带上的一口高产油气流井 ,采用地面直读系统 ,进行了压力降落、压力恢复两次探边测试。压降测试基本测出了古潜山油藏双重孔隙特征 ,在压恢测试过程中测得了水边界和断层边界。结合有关试油试采资料 ,对两次探边测试进行了综合分析 ,得知同一油藏由于生产条件不同 ,其地层压力分布也随之变化 ,导致基质岩块向裂缝供油关系发生变化 ,出现不同油藏特征。从而认为 ,对油藏的认识要结合地层的具体情况 ,应用有关地质资料进行综合分析 ,方能做出合理的解释。
Well Shu 103 is a high oil and gas flowrate well on the structural zone of palaeozoic burried hills, two limit tests of pressure draw-down and pressure build-up were conducted using surface read-out system. The draw-down test basically found out the double porosity feature of palaeozoic burried hill reservoir, during pressure build-up test, water boundary and fault boundary were revealed .Combined with related well testing and early production test data, this paper comprehensively analyzes two limit tests and finds out that in the same reservoir,formation pressure distribution changes along with different production conditions, results in changs of delivery relationship from matrix to fissures, indicating different reservoir characteristics. Therefore it concludes that, to understand a reservoir, combined with specific formation conditions, must utilize related geologic information to make comprehensive analysis before making a reasonable explanation.
