摘　　要：塔里木盆地哈得逊油田属于典型的薄层底水油藏类型,油层有效厚度较薄,纵向上油层数较多,油井无水采油期短,若采用传统的开发方式开采,不但不能有效抑制底水的锥进,而且油藏的动用储量也较低。为此该油田采用了双台阶水平井开采,以解决单层动用储量较低等突出矛盾。虽然诸多文献已对哈得油田薄层底水油藏的地质、渗流和开采动态特征以及其注采机理做了详尽的研究,但这些理论研究还不能很好的解决哈得油田薄层底水油藏开发所面临的问题。随着油藏采出程度的增大,哈得油田薄层底水油藏的产水规律随着地层能量、双台阶水平井段相互干扰等因素影响逐渐趋于多元化、复杂化。为此必须研究哈得油田薄层底水油藏的水驱模型,以便更好的指导油藏的中后期开发。文章根据哈得油田薄层底水油藏地质特征,在建立了薄层底水油藏地质及渗流模型的基础上,从普通薄层底水油藏水驱模型入手,结合哈得油天油藏实际特征推导出哈得油田薄层底水油藏水驱模型。为油藏及早调控油井、抑制含水高度,提高油藏开发效果提供理论依据。Tarim basin HADE oil field is a special kind of bottom--water oil reservoir with thin--bedded. The effective net sand is rather thin,there are many oil pays in vertical, the water free oil production period is comparatively brief. It can＇t acquire perfect effect of the choking the bottom--water coring and the producing reserves of petroleum reservoir is low if we adopt the traditional development technique. So it adopt two benchs horizontal well development technique to resolve the above questions. Although some lit- eratures have research exhaustive to geologic reservoir , filtration feature, producing characteristic and injection/production mechanism of the HADE oil field,but all of these theories can＇t resolve the facing ques- tions to product of bottom--water oil reservoir with thin--bedded. Accompany the productiong of oil reservoir ,the regularity of producing water change complexing and multivariate because the affection of the producing energy and interactive of the two benchs horizontal. So we must research the waterflood mo- die of HADE oil field in order that producting the bottom--water oil reservoir with thin- bedded in midrange -- upper. This paper introduce the waterflood modle of the ordinary bottom--water oil reservoir with thin--bedded to fetch the waterflood modle of the HADE oil field bottom--water oil reservoir with thin--bedded foundation the geologic reservoir of the oil field. The research fruit supply a theoretical basis to choke the bottom--water coring and production the oil reservoir high efficiency.
