| Abstract: | The paper concluded many current problems of pressure tests on casing in drilling operation, analysed the distribution of hydraulic column pressure inside and outside the casing on various conditions in theory, andexplained the effect of pressure tests on casing by differential pressure between both sides of casing through example. Finally,a reasonable method of pressure tests on casing is presented. |
