1)  development in high watercut stage
高含水期开发
2)  high water-cut development period
高含水开发期
1.
The remaining oil distribution during high water-cut development period was controlled by the fluid properties and pore configuration of rock.
处于高含水开发期油藏的剩余油分布主要受流体性质和岩石孔隙结构的影响,而经典数值模拟并没有考虑微观孔喉特征的影响。
2.
After analyzing different scale reservoir development methods, the paper indicates that study based on micro seepage mechanism and macro reservoir simulation should be used to calculate liquid distributing features during high water-cut development period.
在分析不同尺度油藏动态研究方法的特点基础上,指出处于高含水开发期间的油藏需要将微观研究与宏观研究相结合来得到此时地下流体的分布规律。
3)  late high water-cut stage
高含水开发后期
1.

补充资料:欧洲式期权、美国式期权与亚洲式期权


欧洲式期权、美国式期权与亚洲式期权


  【欧洲式期权、美国式期权与亚洲式期权】期权合约所规定的权利有一定的时效期,过了失效日后,权利即行作废。一些期权规定权利仅能在有效期的最后一天执行,这种期权被称为欧洲式期权(ell功pean叩tions);另一些期权则容许在有效期内任何一天执行,这种期权被称为美国式期权(一~oPtions)。值得指出的是,虽名为欧洲式或美国式期权,但已无任何地理上的意义。由于欧洲式期权的规定过于严格,又出现了一种“改变的欧洲式期权”,它允许期权在一定的时间范围内进行交易。可见,美国式期权为期权购买者提供了更多的选择机会,因此,它的购买者也往往需支付更高的保险费。近年来无论在欧洲或美国,所交易的期权均以美国式为主,欧洲式期权虽仍存在,但其交易量已比不上美国式期权。 在so年代末期,市场上又出现了一种所谓亚洲式期权(asian ontions),但也无地理上的意义,其差别主要在于履约价值(exe而sev公此)的计算。以买权为例,无论是美国式期权或是欧洲式期权,执行权利所能得到的履约价值均为当时标的物的市价减去履约价格,再乘以合约所定的数量,但亚洲式期权的履约价值则为权利期间内标的物市价的平均(计算至履约日为止),减去履约价格,再乘以合约所定的数量。
