摘要

根据东营凹陷相-势控藏理论,结合相关调研资料对相-势控藏作用的原理进行了一定的分析,并在此基础上量化地讨论了成藏期“相”、“势”的恢复,认为包裹体恢复的古压力为充注完成后的“剩余压力”。结合成藏期阶段式充注的特点,讨论了充注过程中各种能量的相互关系。探讨性地采用了类比法研究了成藏期的储层孔隙结构,以利92—利54—利853 剖面为例求解了成藏期含油饱和度关系式,并计算了剖面在各个成藏期的含油饱和度,认为利85 区块成藏第三期为主要充注时期。

Abstract

According to the theory of facies-potential controlling on hydrocarbon accumulation in Dongying Sag, in combination with related research, the mechanismof facies-potential controlling on pool formation is analyzed. Based on previous studies, a quantitative research on facies and fluid potential recovery during the hydrocarbon accumulation period is carried out and the recovered palaeopressure in the inclusion is deemed as “residual pressure” which was formed after the filling process completed. In combination with the characteristics of staged filling process during the hydrocarbon accumulation period, interrelations of all kinds of energies are discussed. An analogical method is used to study the reservoir pore structure in the hydrocarbon accumulation period. Taking the linked well section among Li 92, Li 54, and Li 853 in Li 85 block as an example, the equation of oil saturation is formulated, the oil saturation of this section in each hydrocarbon accumulation phase is calculated, and it is concluded that the main filling process was in the third phase for Li-85 block.
