摘　　要：采用生产预测模型对陕45井区进行了开发动态预测，并与压降法储量计算结果进行了对比。结果表明：采用生产预测模型计算的陕45井区可采储量为179．5×10^8m^3，而采用压降法计算的可采储量为145.9×10^8m^3。分析认为，由于陕45井区属于复杂的裂缝-孔隙气藏，裂缝发育相对较差且不均匀，造成地层压力降落不均衡，从而导致压降法储量计算结果偏低。The dynanfic development conditions of well Shaan45 area were forecast by using a production prediction model, and compared with reserves calculation results of pressure drawn-down method. The results show that the production model predicted recoverable reserves of well Shaan45 district are 17.95×10^8m^3, while the pressure drawn-down method predicted recoverable reserves are 14.59 ×10^8m^3. Analysis of the reasons indicates that the well Shaan45 district belongs to the complex fracture - pores-type gas reservoir with uneven development and relatively poor fractures, causing the uneven formation pressure drop, thus resulting in low calculation of reserves by the pressure drop method.
