金风6井探边测试早期评价

Early Time Evaluation of Limit Test of Well Jinfeng 6.

金风 6井白云质泥岩油藏探边测试压力动态成果较准确地揭示了裂缝储集、渗流物性 ,落实了油藏裂缝发育范围。通过地质静态资料与测试压力动态资料相结合 ,实现了利用单井资料有效评价一个油藏的目的。建议在复杂类型油藏早期评价中 ,推广探边测试工艺 ,在开采过程中严格控制采油速度 ,以免导致泄油区内地层压力急剧下降 ,产层裂缝早期闭合 ,岩石骨架和地层束缚水急剧膨胀 。

The pressure performance results of limit test in dolomitic mudstone reservoir of Well Jinfeng 6 have accuratelyrevealed the fissure storage and percolation flow physical properties,and verified the range of reservoir fissuredevelopment. Through the combination of static geologic data with dynamic test pressure performance data,theobjective of using individual well information to effectively evaluate a reservoir has been realized. This paperproposes to popularize limit test technology in the early time evaluation of complicated reservoir,to strictly controloil recovery rate in the course of production,to avoid causing rapid drop of formatioin pressure in drainage area,early time closure of payzone fissures,drastic expansion of matrix and irreducible water and finally causing seriousconsequence of obvious drop of recovery efficiency.
