APPLICATION STUDY OF THE ASPHALTIC HEAVY OIL CONTROLLING TECHNOLOGY IN WELL TK305, TAHE OILFIELD
塔河油田TK305井沥青质稠油防治技术的应用研究

The oil properties in Well TK305 change with production, from the milk yellow condensate light oil in the early stage of production through the brown-yellow condensate light oil to the brown-yellow condensate oil and black heavy oil. Because the oil properties have changed, this well cannot produce normally. Aiming at this practical problem of production, the technology of controlling heavy oil by mixing high-temperature asphalt dispersing agent is presented. Based on the experiments, this well is conducted by broken down technology, achieving some effects.
