npukapnamb■油田的特征是生产层的储油性质差·当开来目标的总厚度为100至600米时,在剖面上可分成20—30个厚度从1-25米的生产夹层,总的有效厚度为30—9O米。夹层渗透率变在0·1至60-70毫达西之间。对大多数油藏来说目前的地层压力都大大低于静水压力。nnukannamb(?)主要矿床中的石油是重的(r=O·8-0·87克/CM~3)带有大量的石蜡(5-15%)与胶油(15-35%)成分。
npukapnamb ■ Oilfields are characterized by poor reservoir properties in the production zone. When the target total thickness is 100-600 m, the profile can be divided into 20-30 production zones with thicknesses of 1-25 m. The total effectiveness Thickness of 30-9O meters. Interlayer permeability changes between 0.1 and 60-70 millidarcy. For most reservoirs, the current formation pressure is much lower than hydrostatic pressure. The oil in the main deposits is heavy (r = 0.8-0.87 g / cm ~ 3) with a large amount of paraffin (5-15%) and gum oil (15-35%).
