玉果油田果1、果4块开发地质评价
|
摘要
玉果油田位于七泉湖构造带中部,油藏埋深大,地震资料品质差,石油地质条件复杂。区块先后钻探井5口,开发井1口,仅有2玉口井获得工业油流,1997年投入试采。2005年投入开发。由于该区钻井少,油藏认识程度低,产能建设难度大。因此,在开发过程中有必要加强油藏跟踪研究,开展油藏地质评价和开发潜力分析,为区块产能建设提供依据。
Yuguo oilfield is located in the centre of Qiquanhu structure belt. Reservoirs are buried deeply, the quality of seismic data is bad, and the geologic condition is complex. 5 exploration wells and 1 development well had been drilled, but only 2 wells obtained industrial oil. Production testing was carried out in 1997. The two blocks were put into production in 2005. Because of drilling few wells and low reservoir understanding for the region, productivity construction is very difficult. Therefore, reservoir tracing research should be strengthen, the geology evaluation and potential analysis should be carried out, which can provide base for the productivity construction of these two blocks.
