摘要
三塘湖油田牛东火山岩油藏储集层非均质性严重,采用自然能量开发效果差。注水开发对于砂岩类油藏是一项成熟的补充能量的开发技术,裂缝对火成岩油藏注水开发效果影响较大。前期该油田已经开展了注水先导试验,并研究注入水推进的方向性及裂缝对注水开发的影响等问题。但是通过实践证明,像砂岩油藏式的注水开发方式并未取得明显效果。针对以上情况和牛东区块储层及开采特征,借鉴国内同类油田注水吞吐开发效果。
The reservoir heterogeneity of Niudong volcanic reservoir in Santanghu oilfield is serious,and the effect of natural energy development is poor. Waterflooding is a mature energy supplement technology for sandstone reservoirs,and fractures have a great influence on the waterflooding effect of igneous reservoirs. In the early stage,the pilot test of water injection has been carried out in this oilfield,and the direction of water injection and the influence of fractures on water injection development have been studied. However,it is proved by practice that the waterflood development method like sandstone reservoir has not achieved obvious effect. In view of the above situation and the reservoir and production characteristics of Niudong block,the development effect of water injection huff and puff in domestic similar oilfields is used for reference. We have explored and carried out water injection huff and puff test in Niudong block.
