污染检测试井新图版及其应用

NEW TYPE CURVES LIKE MCKINLEY TYPE CURVES AND APPLICATION FOR POLLUTION DETECTION *

本研究提出了考虑续流和污染类似于麦金利图版的新图版。这种新图版既适用于压降试井，又适用于压力恢复试井；既适用于具有高传导的垂直裂缝试井，又适用于致密低渗透储层试井分析；既适用于单一介质，又适用于双重介质。

Mckinley type curves is a well test type curves for constant rate.Which applicable to both of vertical fracture for high transmissibility and of tight formation.But it had been considered the influence of alterflow only and that of skin is neglected. The continuity equation for skin effect and the equation for afterflow effect of single medium and for Laplace transformation t F have been done in this paper.Their solution in Laplace space have been achived.A new type curves like Mckinley type curves for skin effect of single medium in single parameter has been made also. Basides,a new type curves like Mckinley type curves for skin effect of double mediums in two parameters has been made in same way in this paper.
