本研究获得了SLUG试井解与定产量试井解的数学关系式并制作出SLUG试井乘积图版。SLUG试井乘积图版分辨率高、灵敏度好、唯一性强,SLUG试井乘积曲线容易制作。SLUG试井乘积图版可用于一开、一开一关、二开二关、三开三关SLUG试井。
It is intruced a mathematical models of first open slug well test in this paper,which achieved the Laplace space solution it is Laplace transformation for t D/C D.The solution has been compare with the well test soltuion which is constant production.The mathematic relation expression between the first open slug well test solution and this of the constant rate well test have been achieved.The derivative type curves of the constant rate well test have many advantages which are high resolution capability,good senstibility and uniqueness.Base on the mathematical relation expression between the first open slug well test solution and this of the constant rate well test,the phenomenon which the multiplication sloution of the first open slug well test is identical with the derivative solution of the constant rate well test .The multiplication type curves of the first open slug well test have been made.This type curves are identical with the derivative type curves of the constant rate.Their distinguishes are that longitudinal coordinate axis of the multiplication type curves is log[(t D/C D) p Dwfslug ],and that of the derivative type curves is log[dp Dwf / dln(t D/C D)].It is thus clear that the aduantages of the multiplication type curves are high resolution capability,good senstibility and uniqueness. The mathematical models of the multi open and multi shut in slug well test have been estallished in this paper,and their solutions of the Laplace space have been achieved.The mathemalical relation expressions between the solution of the multi open and multi shui in slug well test and that of the constant rate well test.Based on their mathematical relation expression,the multiplication type curves of the first open first shut in and the second open second shut in slug well test have been made. The multiplication type curves are effective tools which are no or samll flush production in the drill stem test(DST)and the damage detect for the exploration wells.The damage evaluation and prediction increase production can be in progress.
