塔北隆起三叠系储集层具有孔隙度由上往下逐渐变好、砂体由北往南增厚、储集性变好的特点；侏罗系储集层具有砂体北薄南厚，孔隙由北往南递增的特点。有粒间孔、粒内孔、填隙物微孔隙和缝隙四种孔隙类型，其中粒间孔占６０％～８０％，是最主要的孔隙。Ⅰ类储集岩Ｐｄ＜０．０１ＭＰａ，Ｄｍ＞５μｍ；Ⅱ类Ｐｄ０．１～２ＭＰａ，Ｄｍ２～５μｍ；匾类Ｐｄ０．２～５ＭＰａ，Ｄｍ＜２μｍ。从Ⅰ类到Ⅱ类，孔队结构由好变坏，毛细管压力由粗歪度变为细歪度，排驱压力和他和度中值压力由小变大、孔喉半径不断变小、储集性也不断下降。储层发育主要受埋藏深度和断裂及不整合面的控制。
The Triassic reservoir in Tabei uplift has the characteristics that the porosity is gradually getting better from top to bottom and that the sand body is thickened from north to south with better reservoir property. The Jurassic reservoir has the features of thin sandstone with north thin south thickness, Increasing from north to south features. Intergranular pores, intragranular pores, interstitial micro-pores and cracks of four pore types, of which 60% to 80% intergranular pores, is the most important pore. Class Ⅰ reservoir Pd <0.01MPa, Dm> 5μm; Class Ⅱ Pd0.1 ~ 2MPa, Dm2 ~ 5μm; plaque Pd0.2 ~ 5MPa, Dm <2μm. From Ⅰ to Ⅱ, the pore-cell structure changed from good to bad, the capillary pressure changed from coarse to fine, and the displacement pressure and the median pressure increased from small to large, and the pore throat radius became smaller and smaller Set is also declining. The development of reservoirs is mainly controlled by burial depth and faults and unconformities.
