探边测试资料在开发黄沙坨油田中的应用

APPLICATION OF RESERVOIR LIMIT TEST DATA IN HUANGSHATUO OILFIELD

黄沙坨油田是目前已经探明的辽河盆地最大的火山岩油藏,也是辽河油田主要的后续产油区块。为了监测黄沙坨油田开发生产动态,了解在开发过程中压力、温度变化规律,进一步认识火山岩油藏典型特征,2001-2002年采用高精度电子压力计在该区块共进行了数百井次的流压、静压、流温、静温测试,1井次系统试井,3井次干扰测试以及13井次的压降及压力恢复探边测试,通过对这些测试资料的详细分析,对黄沙坨油田的地层参数变化规律、边界变化情况及单井控制的动储量有了一定的认识,为黄沙坨油田进行动态分析及开发方案的制定提供了依据,为其它火山岩油藏的开发提供经验和保证。

As one of the follow-up production blocks, Huangshatuo Oilfield is the largest volcanic rock reservoir in Liaohe Basin. To monitor the development trend of this oilfield, and to investigate the changing patterns of pressure and temperature during development, as well as to further understand the typical characteristics of the volcanic rock reservoir, electrical pressure gauge of high accuracy was used to measure the flowing and static pressure, flowing and static temperature for tens and hundreds of times in 2001-2002, and altogether 1 systematic well test, 3 interference tests and 13 pressure-dropping and restoring reservoir limit tests were conducted. Through the detailed analysis to these testing data, some understandings on formation parameter changing trend, reservoir limit changing and dynamic storage of single well were obtained, and based on which, dynamic analysis and developing proposal for Huangshatuo Oilfield can be fulfilled.
