the numerical model used to calculate steam impregnation radius and rheological parameter of heated oil bearing formation through the data of build up well testing during shut in is a new technique.
利用焖井恢复试井资料,计算蒸汽浸渍半径及受热油层流变参数的数学模型,是一种较新的技术。
paste-like backfill slurry density and the content of fly ash has closely relation with rheological parameter of slurry, slurry density 78% and the content 20% of fly ash is reasonable parameter.
in this paper, the relationship between fluid macroscopic rheological parameter and its conduct in microscope displacement is established.
本文建立了流体宏观流变参数与其在微观驱油表现之间联系。
with the increase of gap width, grouting pressure difference increased rapidly and penetration radius decreased notably. the influence was remarkably affected by the rheological parameter of grouting.
裂隙高度的减小使所需注浆压力差迅速增大,并使扩散半径迅速减小,这种影响随着水灰比的增大而减小。
with the study of the cement flow rule in the crack, we analyzed the influence to diffusion radius by the grouting pressure, cement rheological parameter and grouting time.
