济阳坳陷石油资源勘探潜力及增储领域分析

An Analysis of Petroleum Resources Exploration Potential and New Field of Increasing Reserves in Jiyang Depression

根据济阳坳陷4次资源评价结果,认为对资源潜力的认识是随着勘探认识程度的不断提高而不断深化的,资源基础决定了探明储量的增长能力。济阳坳陷目前探明程度虽然较高,但仍有较大剩余资源潜力。分析表明,目前济阳坳陷探明储量的构成中,岩性、地层、潜山等隐蔽油藏的比例已经逐步占据主导地位,济阳坳陷已经进入隐蔽油藏勘探阶段。前古近系和埋深大于3500m的古近系深层以及资源潜力较大但勘探程度较低的东营凹陷南部缓坡带、车镇凹陷北部陡坡带、临南洼陷等多个地区,是寻找勘探新突破、实现储量持续增长的重点层系和地区。

According to four resource evaluation results in Jiyang Depression,it is regarded that better understanding of resource potential may be gained in pace with the increasing cognition at exploration.Growth in proved reserves depends on resource base.The exploration degree in the Depression is relatively high,but remaining resource potential is great.Analysis shows that subtle reservoir such as lithologic reservoir,stratigraphic reservoir and buried-hill reservoir dominates the proved resource composition.The Depression has entered into the period of subtle reservoir exploration.Pre-Paleogene and deep layer of Paleogene with burial depth exceeding 3500m,and the southern ramp in Dongying sag,northern steep slope in Chezhen sag,Linnan sag in Huimin Depression with large resources potentials but low exploration degree will be important strata and regions to make new break and achieve sustained reserve growth.
