古城油田泌浅10断块构造应力分布研究及应用

Stractural Stress Distribution of Fault Block Miqian 10 in Gocheng Oilfield

在对古城油田泌浅10断块构造特征分析研究的基础上,开展了构造应力场研究,揭示了构造应力分布规律,为有效抑制蒸汽吞吐井间的汽窜提供了理论依据。矿场应用增油效果显著,提高原油采收率3.6个百分点。

On the basis of structural characteristic analysis of Block Miqian 10 in Gucheng Oilfield, a study is conducted on a structural stress field, by which the structural stress distribution rules are revealed, and theoretical bases are provided for eliminating interwell steam channeling in steam soak. The effect of oil production increase is obvious in oil field application, with 3. 6% increase of oil recovery ratio.
