Experiment for Improving Heavy Oil Recovery by Combination Steam Stimulation Process

Abstract

Abstract: In order to improve the development effect of Xinjiang heavy oil thermal recovery, seek a more comprehensive and more effective measures for incremental production of wells, this paper presents the experimental study by combination stimulation in view of the gelological characteristies of Qigu heavy oil reservoir in District 9(7+8), in which physical modelling and numerical modelling are carried out, including the technological mechanism, the screening and evaluation of combination stimulation expansion agent in different viscosities of crude oil, the evaluation of combination stimulation core flooding experiment and the optimization studies of combination stimulation injection process and injection parameters, as a new technology for improving the efficiency of steam flooding oil and reservoir recovery.

Key words: Karamay field, heavy oil production, combination stimulation, expansion agent, synergist, oil displacement efficiency, recovery
