摘要
塔河油田碳酸盐岩油藏具有埋藏深、非均质性强的特点，主要储集空间以溶孔、溶洞和裂缝为主，裂缝为主要渗流通道。随着油田能量的递减，注水做为补充能量最经济有效的方式得到大力推广。根据物质平衡原理，依托酸压曲线、注水指示曲线、能量指示曲线，对注水进行定量化计算，精细注水，明确注采关系，优化注采参数，推动油田提高水驱效率和采收率。
Abstract
Carbonate reservoirs in the Tahe oil field are featured by great burial depth and strong heterogeneity. Oils mainly reserved in dissolved pores, caves and fractures, while fractures worked as the main seepage way. As formation energy decreases in oil field, water injection has become a most promoted way to supply energy thanks to high economic returns. According to the principle of material balance, with acid fracturing curve, water flooding curve and energy curve, we calculated the volume of water, made a better understanding of the relationships between water injection and recovery, and then optimized injection-production parameters, to improve the water flooding efficiency and oil recovery.
