摘　　要：疏松砂岩油气藏在开采过程中出砂会导致油气井产量下降,甚至井停产、报废。针对海上某油田,通过岩心实验,预测临界生产压差,分析整个开采过程中储层出水、压力衰减等因素对临界生产压差的影响,为海上油气田设计合理生产压差和防砂措施提供依据和参考。The production of sand in loose sandstone oil and gas reservoirs during the mining process will lead to a decline in the production of oil and gas wells,and even the production of wells will be suspended or scrapped.For an offshore oil field,through core experiments,the critical production pressure difference is predicted,and the influence of factors such as reservoir water output and pressure attenuation on the critical production pressure difference during the entire mining process is analyzed.Provide basis and reference for the design of reasonable production pressure difference and sand control measures for offshore oil and gas fields.
