摘要

摘要: 深层高压低渗油藏衰竭开发后存在气液两相流，开展CO₂混相驱渗流特征复杂，需要进行深入研究。模拟深层高压低渗油藏环境，应用细管、长岩心实验开展了CO₂驱室内实验研究。研究表明，该类油藏衰竭开发后，地层呈现双相流，CO₂驱最小混相压力呈下降趋势，CO₂驱油效果大幅下降，但注气恢复压力后开发可达到在原始地层条件下连续注CO₂的驱油效果。研究成果有效指导了现场应用，中原胡96块深层高压低渗油藏CO₂驱先导试验取得良好效果，为有效动用深层高压低渗油藏提供了技术支持。

Abstract: Gas and liquid flows coexist in deep-buried high-pressure low-permeability reservoirs after natural depletion. Further studies are demanded due to the complicated characteristics of CO₂ miscible flooding. The environment of deep-buried high-pressure low-permeability reservoir was simulated and the laboratory experiment of CO₂ flooding was carried out using slim tube and long core. It has been concluded that after natural depletion, gas and liquid flows coexist in formation. The minimum miscible pressure (MMP) and the effect of CO₂ flooding decline. But after restoring formation pressure, the effect of CO₂ flooding increases, and achieves the similar result to that by continuous CO₂ injecting under original formation pressure. The conclusion has been applied in CO₂ flooding pilot test of deep-buried high-pressure low-permeability reservoirs in block Hu96 in the Zhongyuan Oilfield, providing technical support for the development of deep-buried high-pressure low-permeability reservoirs.
