摘　　要：针对海上多层薄互层砂岩油藏受储层品质及层间干扰影响,定向合采井产量预测难度大的问题,以渤海L油田为例,基于矿场资料,利用生产井产出剖面测井二次解释结果,分析不同类型储层的产能初值以及产出层比例情况,并建立多层合采井产量预测模型。研究发现,不同类型储层合采的情况下,Ⅱ类储层和Ⅲ类储层存在产量贡献,且产能以及产出层比例较低;在新井配产过程中,需充分考虑不同类型储层的产出能力,提高合采井产量预测精度。In view of the difficulty of production prediction of directional combined production wells in offshore multi-layer thin interbedded sandstone reservoirs affected by reservoir quality and interlayer interference,taking Bohai L oilfield as an example,based on field data,using the secondary interpretation results of production well production profile logging,the initial productivity values and the proportion of production layers of different types of reservoirs are analyzed,and the production prediction model of multi-layer combined production wells is established.The results indicate that in the case of combined production of different types of reservoirs,type II and type III reservoirs have production contribution,and the productivity and the proportion of production layers are low.In the production allocation process of new wells,the production capacity of different types of reservoirs should be fully considered to improve the production prediction accuracy of combined production wells.
