Abstract: In this paper, the basic geology, chemical principle, comprehensive utilization of well logging, mud logging, testing, and geological information, such as gas injection of deep heavy oil testing process to evaluate the application of the K119 well, through the K119 deep heavy oil well construction step, and the evaluation of the effect of the testing process, explore the advantage of deep heavy oil testing, process, deepen the understanding of deep test process of heavy oil. Using the method of mathematics, chemistry, and combined with a large amount of operation data, in this paper, the test process of heavy oil deep in the K119 to evaluate the application of the well, deeply recognize that USES the injection-production integration process can reduce the cold damage to reservoir, reduce construction work; Heat pipe has very good heat preservation effect, it can extend the production cycle; CO2 can improve the reservoir properties, has the very good viscosity cleanup action; Electric heating technology can improve the pump efficiency and prolong the well stimulation cycle.
