The pressure drop equation was derived from the volume balance principle in allusion to the characterization with abnormity of pressure-drop plot and constant-volume in overpressure gas reservoir.
针对异常高压气藏具有压降图异常和定容封闭的特征 ,基于体积平衡原理 ,导出了异常高压气藏的压降方程 ,并结合气井的二项式渗流方程和气体的井筒流动方程 ,建立了异常高压气藏动态预测基本模型 ,在模型中考虑了储气层的压实和岩石颗粒的弹性膨胀作用 ,以及地层束缚水的弹性膨胀作用。
The method of vitrinite reflectance is combined with the method of volume balance-sedimentation rate to have restoration to T_5 unconformaty, and the method of vitrinite reflectance is combined with stratum trend method and sedimentation rate method to have a .
利用镜质体反射率法和体积平衡-沉积速率法相结合对T5不整合面进行剥蚀量恢复;应用镜质体反射率法、地层趋势分析法和沉积速率法相结合对T4不整合面进行剥蚀量恢复。
Conclusions that the change of impounding time only alters the reservoir s sediment deposition rate and silt-stable time, but cannot change the sedimentation q.
结果表明:三峡水库汛末推迟或提前蓄水,只是改变了水库的淤积速率和到达淤积平衡的时间,而不能改变水库淤积平衡时的淤积总量。
Following the criticism of "opposition to rash advancement" there appeared an interaction among the so-called theory of " positive balance," a political climate of boasting and exaggeration in production and construction and arbitrary administrative operation.
1957年批判"反冒进",形成了所谓"积极平衡"的理论、生产建设中浮夸风的政治气候和行政运行上的互动机制。
