in a word, the effect of connate water and stress sensitivity on development of low-permeability gas reservoir should be paid enough attention.
共生水的存在以及应力敏感性对低渗气田开发的影响应引起足够的重视。
it has been proved by experiments that there's stress sensitivity in some low-permeability gas condensate reservoirs, and higher the connate water saturation, stronger the stress sensitivity.
实验已经证实一些低渗深层凝析气藏存在应力敏感性,共生水含量越高,对压力的敏感性越强。
well test data of such reservoirs are hard to analyze by conventional well test models, which should be properly modified when the connate water saturation is high.
connate water can be dense and saline compared with seawater.
与海水相比,原生水要重一些,是盐水。
connate water is also described as fossil water.
原生水也被描述为化石水。
due to the variation of geologic environment reservoir is often invaded by external water, thus, resulting in the property difference between connate water and formation water.
油藏形成后,由于地质环境变化,储层往往会受到外部水系的侵入,从而造成原生水和水层地层水性质的差异。
the chemistry of connate water can change in composition throughout the history of the rock.
