摘　　要：X6176区块油层埋藏浅,渗透率低,储层能量衰减较快,针对区块储层的地质特征,利用油藏数值模拟软件建立了整体压裂开发的数值模型。以整体压裂改造后的初期产量、最大采出程度和经济效益为目标,进行了裂缝参数(裂缝缝长、导流能力)多因素分析优化研究。通过现场试验两口井与前期施工井的对比,产量增幅分别为76.2%和11.5%,增产效果较为显著。Reservior in block X6176 has the geological characteristics of shallow burial depth, low permeability and rapid decay rate of reservoir energy. By using reservoir simulation software, numerical model of intergral fracturing development was formed up. Meanwhile, multivariate analysis optimization reserch for fracture parameters such as fracture length and flow conductivity were done with goal of initial production, maximum recovery degree and economic benefit after integral fracturing. Compared with pre-construction wells, two wells in field test obtained the production of each increased by 76.2 % and 11.5 %. The stimulation ef- fects were remarkable.
