With the increasing of oil well and producing reserves, it is difficult for conventional artificial lift technology to meet the producing need.

The paper analyses the effect factors on ternary combination flooding lift technology,compare application conditions and economic benefit of three lift technologies in ternary combination flooding and select a lift technology suited for ternary combination flooding.

The reservoir performance is the design basis of the steam injection and the lifting technology, whereas, the steam injection and the lifting technology affect the reservoir performance.

Based on the research of viscosity?temperature relationship of heavy oil, lifting technology in deep wells and mixing light oil for viscosity reduction, the feasibility of lifting technology of hollow rod is studied.

The flow and heat transfer thermal-dynamic model for the fluid flowing along wellbore by using the blending diluting oil technology to reduce the viscosity was established on the basis of heat transfer principle and two-phase flow theory.
