三角洲前缘相沉积体系主流带调剖模式研究

Research of a Profile Mode of the Main Flow Belt of Front Phase Facies System

化学浅调剖技术是注水结构调整的重要手段。南一区高台子油层为三角洲前缘相沉积,储层纵向层间矛盾突出,但各单元储层发育规模较小,细分单卡余地小,给油田开发调整带来困难。应用在前缘相沉积体系渗流特征和化学浅调剖技术结合上进行了探索和研究,建立了前缘相沉积体系主流带调剖模式。提出了前缘相调剖的新思路,新方法。深化了注水结构调整,控制了前缘相沉积体系的含水上升速度,见到了明显的技术经济效果,具有广阔的应用前景。

The technique of general chemical profile control is an important means of structural adjustment of water injection technology.Gaotaizi reservoirs in the Southern District is a delta of front phase facies,the reservoir contradiction between the longitudinal layers is prominent,but all kinds of unit reservoir development and subdivision single card room are smaller,which bring to the difficult of the adjust to the oil field development.Exploration and research are carried out by combined with front phase facies sedimentary system and technical of general chemical profile control,established a profile mode of the main flow belt of front phase facies system,and proposed new ideas and new methods of front phase profile.The structural adjustment of water injection is deepen and increased rate of water of front phase facies system is controlled,it sees the obvious technical and economic effects,has broad application prospects.
