摘要
介绍新时期油气钻井工程定位、特征、发展趋势及正在经历的3个转变;分析用工程技术提高单井产量与采收率的4种途径:增大井底压差、减小油气流动阻力、增大井眼与油层接触长度和保护油气层;论述利用钻井新技术提高单井产量的可行性.结合保护油气层、特殊工艺井钻井等新技术的原理及应用情况,阐述应用油气钻井新技术提高单井产量与采收率的效果、优势与前景;指出提高单井产量是一项系统工程,必须科学合理地选择和规划,应该大力发展相关钻完井关键技术与装备.
The paper introduces three major transformations in well drilling engineering orientation,its characteristics and its potential development in the new era,analyzes the four approaches to the increase of well production and recovery rate with the improvement of engineering techniques,i.e.,increasing the pressure differential in the bottom hole,decreasing the resistance to the oil-gas flow,increasing the contact length between the well bore and the reservoir and protecting the oil-gas layers.The feasibility o...
