吐哈三大主力油田鄯善、丘陵、温米都已进入中高含水期,水淹面积逐渐增大,加密井的风险不断增大,油田稳产难度日益增大。如何准确地预测剩余油分布以完善注采关系和提高加密方案的钻井成功率,已成为现阶段油田开发的主题。采用了新的思路和技术,结合吐哈油田的实际特点,运用油藏数值模拟方法对剩余油分布规律进行了研究,取得了一些新的认识。 Tuha three major oil fields Shanshan, hills, temperature meters have entered the high water cut period, water flooding area gradually increased, the risk of infiltration wells continue to increase, the difficulty of steady oil production increasing. How to accurately predict the remaining oil distribution to improve the relationship between injection and production and improve the drilling success rate of the encryption scheme has become the theme of oilfield development at this stage. With the new ideas and technologies, combined with the actual characteristics of Tuha oil field, the distribution law of remaining oil was studied by using reservoir numerical simulation method, and some new understandings were obtained.
