摘要

主要重点是探索深层、低渗透和水敏感储层的最佳注气开发模式。确定了液态二氧化碳注入的技术极限,有效指导了注入参数设计。设计了新型防腐蚀、气密性好的注气管串,确保注气安全高效。现场试验的成功为深层、低渗透和水敏感储层提供了有效的能量补充方法,也为下一步其他类似储层的有效利用提供了技术参考。

Technology Optimization and Field Test for Improving Development Effect of Deep Low-Permeability Water-Sensitive Reservoirs
The main focus is on exploring the optimal gas injection development model for deep, low permeability and water sensitive reservoirs. The technical limit of liquid CO2 injection was defined, which would effectively guide injection parameter design. A new type of anti-corrosion and gas-tight injection string were designed, which would assure safe and efficient injection. The successful field test provided an effective energy replenishment method for deep, low permeability and water sensitive reservoirs, and also provided technical reference for the effective utilization of other similar reservoirs in the next step.
