辽河油田稠油水平井井身结构设计原则与方法研究，经过几年工作，已基本掌握了稠油水平井结构设计的基本思想、影响井身结构设计的主要因素和设计稠油水平井井身结构的方法。通过辽河油田几口稠油水平井的钻井实践，表明该课题所论及的内容有较强的科学性及现实性，完全满足稠油热采水平井的需要，而达到国内较高水平。 After several years of work, the basic idea of ​​structural design of heavy oil horizontal wells has been basically mastered. The main factors affecting the design of wellbore structure and the method of designing the wellbore structure of horizontal wells in heavy oil have been basically mastered . Through the drilling practice of several heavy oil horizontal wells in Liaohe Oilfield, it shows that the content of this project is scientific and realistic, which fully meets the needs of horizontal wells for thermal recovery of heavy oil and reaches a relatively high level in China.
