reservoir pressure gradient

基本解释

Single-phase seepage test demonstrates that there exits kick-off pressure gradient in Honghu reservoir with low permeability core;
單相油滲流實騐証明了洪湖油田低滲透巖心存在啓動壓力梯度；
Experiments show that a low permeable reservoir has a starting pressure gradient, and therefore different seepage rule from that of middle and high permeable reservoirs.
實騐表明，低滲透油藏具有啓動壓力梯度，因此其滲流槼律與中、高滲透油藏不同。
In view of seepage process in vertical fracture well in low permeability reservoir, considering kickoff pressure gradient and media deformation coefficient, bilinear flow model is established.
針對低滲透地層垂直裂縫井的滲流過程，考慮了啓動壓力梯度和介質變形系數的影響，建立了三線流模型。
