摘　　要：根据数值试井分析方法,建立了非均质油藏抽汲井的定产量试井模型,在考虑井筒储集效应和表皮系数的情况下,建立块中心网格对定解问题离散后编写软件求解。对求解压力进行压力及其导数双对数分析,得到了不同平面非均质油藏抽汲井定产量生产压力导数典型曲线。Test model of swabbing well with well bore storage and skin effects in heterogeneous oil reservoir,under the condition of constant flow rate,has been built by numerical well test,and the mathematics problem of the model is solved by block-central-grid network,dispersing and software. The calculated pressure data are analyzed by log-log analysis of pressure derivative,and the pressure derivative type curves for swabbing well in different heterogeneous oil reservoirs under the condition of constant flow rate are obtained.
