摘　　要：滩坝砂岩油藏具有隐蔽性强、储层横向变化大、储层单层厚度薄的特点,加之受地震资料分辨率低等因素的影响,致使其地震描述及预测难度大。围绕滩坝砂岩油藏的勘探难点,综合运用现代沉积学、石油地质学、地震地层学等技术方法研究了滩坝砂岩的沉积特征和分布规律,明确了滩坝砂岩地震响应特征,开展了滩坝砂岩储层的物探识别、预测技术攻关,形成了一整套勘探技术流程及配套技术系列,在实际应用中取得了较好的勘探效果。Beach-bar sandstone reservoir is characterized by high concealment, variable transversal reservoirs, and thin single bed. Owing to these features and low resolution seismic data, its seismic description and prediction are difficult. Aiming at its exploring difficulties, adopting techniques in modern sedimentology,petroleum geology and seismic stratigraphy, this essay studies its sedimentary characteristics and distribution rule, and summarizes its seismic response characteristics. Having carried out its geophysical identification and prediction, a set of exploration technological process and matching technology are established, which has a good effect in practical use.
