Abstract
Conventional exploration technology can not meet the need of problems caused by high crude oil viscosity, low dynamic fluid level and oil well restarting difficult after pumping off in Well Jian 218x. Based on the experiments of crude oil viscosity-temperature laboratory test, emulsified heavy oil viscosity-temperature test and visbreaking additive selection test, considering the reservoir characteristics and development situation in Well Jian 218x, formation pre-processing chemical visbreaking combined with coaxial dual-hollow rod inner circulation heating visbreaking to improve the technology. Field application shows that oil productivity has been increased significantly, and was worthy to learn for the similar cases.
