The scientific basis of the paper is the concept of renewability of oil and gas resources. In accordance with this concept, the purpose of this paper is to estimate the volumetric rate of natural replenishment of the reservoir with oil and gas using the example of long-developed Bibieybat oil and Garadag gas condensate fields in the South Caspian Basin (SCB). The methodological approach of this assessment is based on the authors' assumption that at the late stage of field development, the recoverable amount of hydrocarbon fluids is compensated by the amount of their natural inflow, as a result of which oil or gas production stabilizes. The analysis of the dynamics of hydrocarbon production for the Bibieybat oil field covered the period from 1935 to 2018, and for the Garadag gas condensate field from 1955 to 1979. The rate of natural oil replenishment calculated for 29 operating facilities of the Bibieybat field varies per well within 0.32–1.4 ton/day (averaging 0.76 ton/day) or about 277 ton/year. The rate of natural gas inflow at the Garadag gas condensate field is about 5.2 thousand m3/day per well.

南里海盆地长期开发油田的油气生产动态,着眼于储量的可更新性

本文的科学依据是油气资源可再生性的概念。根据这一概念,本文的目的是以南里海盆地(SCB)发育较久的Bibieybat石油和Garadag天然气凝析气田为例,估算油气储集层的自然补水率。这项评估的方法学方法是基于作者的假设,即在油田开发的后期,烃类流体的可采量被其自然流入量所补偿,从而使油气生产稳定。对Bibieybat油田1935年至2018年以及Garadag凝析气田1955年至1979年的烃类生产动态进行了分析。为Bibieybat油田的29个运营设施计算的天然油补给率在每口井0.32至1.4吨/天(平均0.76吨/天)或约277吨/年之间变化。Garadag凝析气田的天然气流入速率约为5.2 m每孔3天/天。
