BD油藏裂缝预测及剩余油研究

江苏BD阜二段油藏为低渗裂缝油藏，水驱开发效果相对较差，多数油水井因高含水停采停注，由于裂缝影响，对剩余油的认识难度较大。针对油田的地质特征和见水状况，重点是利用地震资料模糊识别技术建立数学模型，提取地震特征分析储层的裂缝发育规模，在结合沉积相、裂缝等认识的基础上，重新建立精细地质模型，运用水驱特征曲线及数值模拟等方法测算和模拟目前的剩余油分布现状，现场调整井实施后验证了对剩余油的认识，并取得了一定的效果，为后续的继续调整提供了依据。

FRACTURE FORECAST AND REMAINING OIL OF BD OIL RESERVOIR

Pu member 2 reservoir,Jiangsu BD,is a low permeability fractured one.Effectiveness of water flooding is relatively poor,the majority of the oil wells,because of high watercontaining,is stopped producing and injecting,awareness of the oil is very seldom duo to the fracture influence on the remaining oil.Aiming at the oilfield geological characteristics and waterproducing situation,the focus is to use seismic data fuzzy recognition technology to establish mathematical model of reservoir characteristics and fracture development scale by analyzing seismic characteristics，in the combination of sedimentary facies and fractures,the fine geological model is re-established,water drive characteristic curves and numerical simulation are applied to calculate and simulate the distribution of remaining oil,the insitu adjustment wells after operation verifies the recognition of remaining oil,some effects are achieved,and foundation is provided to followingup continuous adjustment.
