摘要

油气成藏与油藏开发得以实现的基础是存在能量差, 流体(烃类流体或油气水)作为能量传递的载体, 在地质体中建立动态的能量平衡。油气成藏与油藏开发流动的流体和流动的环境都是相似的, 这种动态相似性为成藏动力学定量研究开辟了新的途径, 即可以借鉴油藏开发的理论和技术方法研究成藏动力学。在油藏开发过程中, 影响油气产量的开发地质因素同样影响成藏时的油气充满度。砂岩体的储集特征受到岩性差异、粒度变化、胶结差异等层内非均质、层间非均质及各向异性等因素的综合作用。当其中某种因素成为影响砂岩储集特征的主要因素时, 同样影响油气充满度, 并表现出巨大的差异。油气成藏与油藏开发有着相似或相近的影响因素, 这也说明在研究油气成藏时借用油藏开发的技术方法是可行的。

Abstract

Both o il and gas form ing and rese rvo ir deve lopm ent are
based on the ene rgy d ifference. The flu id m akes the dynam ic
energy ba lance in the g eo logy body in the form of convey ing
energy. The fluid and env ironm ent of o il and gas form ing and
reservo ir developm ent are both sim ila r. Th is sim ila rity has
prov ided a new path to study o il and g as form ing dynam ics.
M any theo ries and techno log ies o f reservo ir deve lopm ent can
be applied to study o il and gas form ing dynam ics. The
geo log ic factors to a ffect o il and gas production s im ilar ly
influence on o il and g as filling degree. The reservo ir
characteristics of sandstone body is affected by m any factors
such as litho logy d ifference, granu larity va riety, cem ent
d ifference, interna l heterogeneous, inter layer hete rogene ity and
an iso trop ism. When one of these fac to rs is the ma in factor, it
sim ilarly affects fill deg ree and show s great d ifference. What
there a re sim ilarly influence factors for o il and gas fo rm ing
and reservo ir developm ent also illustrates tha t it is impossible
to apply the techno logy o f rese rvo ir deve lopm en t in to o il and
gas form ing.
