摘要：滩坝砂岩油藏是一种重要的岩性油藏类型，具有分布复杂、预测难度大的特点。以潜海南部海域A油田为研究对象，探索出一套适用于海上大井距条件下中深层灌坝相储层沉积规律精细刻画和预测技术。首先通过大量的岩心观察，明确研究区滩坝相沉积背景；其次通过精细古地貌恢复明确大规模滩坝砂分布的可能，综合古水动力和古风力研究明确沉积边界；最后通过地球物理正演实验和GeoFrame软件的LPM模块技术，确定出滩坝砂体的沉积厚度。研究结果表明该技术具有较好的应用性，为海上油田中深层滩坝相储层精细刻面提供了新
思路。

Abstract: The beach bar sandstone oil reservoir is an important type of the lithologic reservoir which is character-ized by the complex distribution and hard prediction. Taking Oilfield A in South Bohai as the research object, a set of the fine description of the sedimentary laws and predicting technique were explored for the middle and deep beach-bar-facies reservoirs under the condition of the offshore large well spacing. At first, with the help of vast core eeeeaaeeeeea palaeogeomorphic restoration, a large scale of the beach bar sand distribution was determined, and moreover com bined with the palaeo-hydrodynamic and palaeo-wind-power researches, the sedimentary boundaries were verified; finally by means of the geophysical forward modeling experiment and LPM module technique of GeoFrame Software, the sedimentary thicknesses of the beach bar sandbodies were determined, The study achievements show that the technique possesses much better applicability and provides a new idea on the fine description of the middle and
deep beach bar facies reservoirs of the offshore oilfield. 收稿日期：2016-07-19
