本刊在一九七七年第六期上曾发表了题为《灰岩和砂岩油、气田储量计算的诺模图》一文。这里再将计算气田单储系数和地质储量的对数坐标系诺模图作一补充。气田单储系数的计算公式为:气田地质储量的计算公式为:N_g=0.01FhφS_gβ_g=Fhn_g(3)式中:n_g=单储系数,地面标准亿方/公里~2·米; The journal published a sixth article in 1977 entitled “Limestone and Sandstone Oil, Computation of Gas Field Reservoirs”. Here again to calculate the gas field single storage coefficient and geological reserves of logarithmic coordinate system diagram as a complement. The formula for calculating single reservoir coefficient is as follows: Ng = 0.01FhφS_gβ_g = Fhn_g (3) where n_g = single storage coefficient, ground standard 100m 2 / km to 2m;
