Shallow horizontal well technology of trajectory control and casing string running for heavy oil field

By using horizontal well technology to develop Kramay heavy oil field can reduce investment and get beneficial results.The reservoir of heavy oil in Kramay oil field is shallow and its viscosity is high.For thermal production,high diameter completion pipe is used.When using horizontal well to develop shallow heavy oil,We must to solve these problems: high build rate in big hole,trajectory control in soft formation and big diameter casing run in high dogleg hole.This paper analyzed and introduced the key technology in trajectory control and casing string running technology for shallow horizontal well in heavy oil field,and proposal good experiments for similar project.
