Abstract

Abstract: In view of the high water content and the low heat utilization rate faced by the steam flooding development of Qi 40 Block in Liaohe Oilfield, a full life cycle evaluation method of steam flooding was proposed, and a design method of injection-production parameters for each flooding stage was established. The research results show that: based on the correlation between viscosity and temperature of heavy oil, the current "three fields" of steam flooding can be modified to "four fields", which can more intuitively evaluate the development effect of steam flooding. Based on the different mechanisms during the steam flooding process, the current "3 stages" of steam flooding was divided into "4 stages", which can more accurately evaluate the whole process of steam flooding.Combining the characteristics of viscosity field and heat utilization situations, design the injection-production parameters for each steam flooding stage: in the establishment stage of temperature field for heat connection and the steam displacement stage, the optimal steam injection intensity was 200 m³/(d·m·km²) and 150 m³/(d·m·km²), respectively; in the injection-production parameter adjustment stage when the steam broke through obviously, the optimal steam injection intensity was 120 m³/(d·m·km²), and the dryness was controlled at about 0.2, which was beneficial to the development effect of this stage. After the full steam channeling of steam flooding, the development mechanism of steam-hot water alternate injection and development mechanism of intermittent steam flooding were analyzed. The two development patterns were compared with continuous steam flooding, and the development effects indicated that steam-hot water alternate injection and intermittent steam flooding were the better freplacement methods after full steam channeling. The research results have certain guiding significance for the steam flooding development of Qi 40 block in Liaohe Oilfield, which can provide a reference for the development of similar heavy oil fields.

Key words: four fields for steam flooding, injection-production parameter design method, replacement method
