摘要: 塔里木油田底水油藏水平井生产的最大优势在于无水采油期,水平井一旦见水后含水上升快。由于缺乏必要的稳油控水配套技术,因此水平井无水期合理的产能将直接影响水平井开发效果。根据水平井油藏工程理论,推导并建立了综合评价水平井无水期合理产能的2个目标函数,提出了底水油藏水平井无水期合理产能的计算模型,并以塔中4油田水平井为例进行了分析验证,结果表明该方法简单实用。

Abstract: The production predominance of horizontal well relies in the water-free producing period in Tarim oilfield. The water cut will rise rapidly once water breakthrough occurs in horizontal well with bottom water drive reservoir. The corresponding measurement method is limited, because it is lack of the feasible and effective matching technologies for stabilizing oil production and controlling water production. So, the water-free production will impact directly on the overall development effectiveness of horizontal well. Based on the reservoir engineering theory of horizontal well, the objective functions of NPP and SNPV for integrative evaluating water-free production of horizontal well were derived and established. The practical approach for determining reasonable water-free production of horizontal well was presented. The calculated results show that it is a simplified and useful approach for determining the reasonable water-free production of horizontal well with bottom water drive reservoir.

Key words: Tarim Oilfield, bottom water drive reservoir, horizontal well, water-free production period, water breakthrough time, reasonable production
