This paper presents the geological design for horizontal drilling in a medium to thin-bed-ed heavy oil reservior in Le'an oilfield. The parameters for steam injection and productionwere optimized with numerical simulation. The actual production performance and effect ofhorizontal wells were analysed and evaluated, compared with that of the vertical wells, it hasbeen proved feasible to recover medium to thin-beded heavy oil reservoir by steam huff andpuff in horizontal wells with a fair economic benefit.
