试油井产量折算新方法

为了使试油折算产量的条件尽可能的相同,增强试油产量的可比性,消除地面计量的人为误差,研究了试油求产时井底流压的变化规律,认为采用油柱在油管内上升的流压变化速率来折算产量更趋于合理,并能最大限度地接近地层真实产量.该方法从根本上消除了因试油周期选定不合理、地面计量误差,以及试油工艺不同、储层条件差异带来的试油产量误差.

A New Method to Convert Production Value in Tested Well

For making qualification of conwerting production value in tested well to be equal which boosts up its relativity and eliminates artificial errors from surface test,the changing rule of down hole flow pressure at time of acquiring production by well testing is studied.It is thought that using the change speed of flow pressure of oil pole uplifting in tube to convert production is much reasonable and ap- proaches the real one farthest.The method removes the production errors from unreasonable of selecting testing cycle,errors of sur- face testing,difference of oil testing tech and diversity of reservoir condition radically.
