摘要： 我国带凝析气顶的油环一般不大,储量只有几百万吨,油环由于窄,打井相对较难命中,这样造成油环区井很少,给评价开发带来困难,特别是因为井少,储量无法计算。塔西南地区黑油储采比很低,只有5:1左右,为了保持稳产,对开发难度大的柯克亚西七二油环进行了评价,探索出一套估算小油环储量的方法-一砂层厚度外 推法估算小油环储量。并针对西七二油环油层众多且薄的特点,建议采用定向穿层水平井技术,以提高油环储量动用程度。

Abstract: The oil rings with condensate gas cap in China are found to be relatively small, with only about several millions of tons of reserves. For the oil ring is generally narrow, it is relatively difficult to drill just into it, and there are few oil-rim wells. Such brings difficulties for evaluation of this kind of reservoir development. Especially, the calculation of reserves can hardly be made. Because of very low reserve-production ratio(only about 5: 1) for black oil in Southwestern Tarim basin, this paper made an evaluation of Xiqi' eroil ring in Kekeya field, a difficult developed small oil ring, and found out a set of methods used for estimation of small oil ring reserves, called net pay thickness extrapolation. Also, this paper suggested that using orientational strati-penetrating horizontal drilling technology can improve the producing reserves.

Key words: Kekeya, condensate field, oil ring, reserve, horizontal well
