三重介质油藏干扰试井压力动态特征
According to interference well testing problems in closed exterior boundary stratum, a theory model of the well testing in closed rounded interior boundary stratum with invariable output is built up and a new theory plate is drew in this paper.
针对封闭外边界地层条件下的干扰试井分析问题,建立了内边界定产外边界圆形封闭的试井理论模型,绘制了新的理论图版。
Based on the summary work of unsuccessful well test and the base of acquiring cognition, the interference well test of double well groups in Chenbao zones has been guided and the compart condition between Chishan groups and Taizhou groups are determined.
经对未成功井例的总结,在取得认识的基础上,指导了陈堡地区两对井组间的干扰试井,落实了赤山组与泰州组间隔层的分隔状况,为区块开发方案的调整提供了科学依据。
On the basis of dual porosity physical model, a mathematical model for interference test in fractured reservoir is developed.
基于双孔隙物理模型 ,建立了裂缝性油藏干扰试井的数学模型。
