Title: Study on conversion of development strategy after cyclic steam stimulation in horizontal well for shallow thin ultra heavy oil reservoir
Abstract: This paper studies the conversion of development strategy after cyclic steam stimulation in horizontal well for shallow thin ultra heavy oil reservoir by using numerical simulation and taking a typical region in Xinjiang oilfield as an example.The result shows that the combination of vertical injector and horizontal producer is a good option of steam flooding after cyclic steam stimulation.The rational parameters are the intensity of steam injectivity is 1.68~2.02 m3/(hm2·m·d),the production-injection ratio is 1.2~1.3;and the steam quality at bottom hole is over 0.4.This study is instructive to converting development strategy in horizontal wells of heavy oil reservoirs.
