摘　　要：牙哈 2 - 3凝析气藏是块状底水气藏 ,水平井开发的适应性研究表明 ,牙哈 2 - 3凝析气藏应用水平井开发具有优越的地质条件。通过各项参数优选研究 ,指出了水平井段最佳优化方位、最佳长度及最佳垂向位置。水平井开发跟踪研究表明 :用水平井开发凝析气藏具有产量高、稳产期长 ;生产压差小 ,可抑制气窜和底水锥进 ;采收率高 ,经济效益显著的独特优势 ,对其它凝析气藏开发具有借鉴意义。Yahaz-3 gas condensate reservoir, the one of massive bottom water, shown by horizontal well developing adaptability research, has advantageous geological conditions in development by applying this well. Through optimization study of various parameters, the best--optimization orientation,--length and --vertical position of horizontal well interval have been demonstrated. It is confirmed by horizontal well tracing research, that by using this well to develop gas condensate reservoir, the yield will be higher, stable production period longer, producing pressure draw-down lower, gas leakage and bottom water coning controllable, recovery factor higher, and economic benefit more obvious, having the significance of referential use for other gas condensate reservoir development.
