摘要
海拉尔油田属于复杂断块油田,岩石类型多样、岩性复杂多变、薄差储层发育、低孔低渗特征明显,水力压裂是其投产及增产的主要措施。针对海拉尔油田低产井的成因及特点进行分类,分析储层客观条件导致的水力压裂难点。阐述压裂技术在海拉尔盆地提高低产井产量上取得的进展,并结合生产现场和压裂技术的新需求,探讨进一步提高海拉尔油田压裂效果面临的难点,认为低伤害、低成本、高效环保的压裂液技术是下步开展压裂技术研究的主要方向。
Hailar oilfield belongs to a complex fault block oilfield,whose types of rocks are multiple,lithology is complex and thin and poor reservoirs develops,characteristics of low porosity and low permeability are obvious,so hydraulic fracturing is the main treatment to increase production.According to classification of the reasons and feature of inefficient wells in Hailar oilfield,hydraulic fracturing difficulties caused by conditions of reservoir is analyzed,the progress of fracturing technology in improving the production of inefficient wells is described,and combining new requirements of production site and fracturing tech,the facing difficulty to raise the fracturing fruit in Hailar oilfield is discussed.It is thought that the low damage,low cost,high efficiency and environmental protection is important research direction of fracturing technology.
