高升油田高 3 块隔夹层特征及对稠油热采的影响

CHARACTERISTICS OF PARTINGS AND THEIR EFFECTS ON THERMAL RECOVERY OF HEAVY OIL OF GAO 3 AREA IN GAOSHENG OILFIELD

通过论述了高３块隔夹层类型、岩性和分布、微观孔隙结构、热物性特征，以及不同类型隔夹层对稠油蒸汽吞吐、蒸汽驱、热水驱的影响，并提出改变原注汽排液井只射开油层下部１／２调整为全部射开。为改善高３块蒸汽吞吐、蒸汽驱、热水驱的开发效果，为增加油层动用状况提供了依据。

This paper discusses the types, lithology and its distribution, micro pore structure,thermal physical properties characteristics of partings of Gao 3 area as well as the effects of different types of partings on steam stimulation , steam flooding and hot waterflooding of heavy oil, and consequently suggests that the whole oil reservoir be perforated for the original steam injection and drainage wells instead of perforating only in the lower half part. It provides basis for improving the development results of steam stimulation, steam flooding, hot waterflooding in Gao 3 area and for increasing oil reservoir production.
