常見例句雙語例句The factors which influence the microfractures are the structural position, compositional maturity, grain size, the quantity of cements as well as specific compaction.影響構造微裂縫發(fā)育的因素是:所處的構造應力部位,巖石成分成熟度、粒度、壓實程度和早期填隙物含量。It is mainly composed of fine-grained lithic feldspathic, feldspathic and feldspathic clastic sandstone with a low compositional maturity and a middle texture maturity;儲集巖主要為細粒巖屑長石砂巖、長石砂巖和長石巖屑砂巖,以低成分成熟度、中等結構成熟度為特征。It is shown that physical characteristics of crude oil depend not only on group compositions, but also on maturity, burial depth, preservation condition and compositional gravity differentiation.原油物性不僅受原油族組成的影響,而且也受成熟度、埋藏深度、保存條件、組分重力分異作用等的影響。 返回 compositional maturity
