    Abstract：In steam flooding test area well group of Du 229 block ultra heavy oil reservoir, steam channeling breakthrough appears in some production wells since rotation drive, which results in such problems in subsequent development as high temperature, high fluid production, high water content and low oil production and affects development efficiency of steam flooding. Analysis results show that such factors have significant effect on development efficiency as each single well spacing, exploitation degree before flooding, well group reservoir physical property difference, anisotropy, dip angle, steam overlap effect and well pattern part imperfection. In order to enhance steam injection efficiency and improve recovery effect, applied are a series of technological means to conduct dynamic control on the well pattern and such purposes are reached finally as steam channeling direction change, steam breakthrough inhabitation and well group area steam balance extension.
