Abstract: Generally speaking, the horizontal section length of Dual horizontal SAGD wells is longer than that of conventional thermal recovery wells. During the production process of SAGD section, it is prone to steam channeling between production horizontal wells and injection horizontal wells and reserves non-uniform used in the horizontal section, which affect the development performance of SAGD well groups and increase the controlling difficulty. In order to improve the uniformity of producing degree in horizontal section, a uniform steam injection theoretical model was established and corresponding pipes were design in this paper. Trial test in the Feng City SAGD has obtained remarkable results, which is useful to future SAGD expand application.
