摘要
为准确计算探明石油地质储量,同时最大限度地控制勘探投资,必须对其井控程度进行合理研究。针对新储量规范对探明石油地质储量计算中井控程度的要求,以胜利油区典型的构造油藏和岩性油藏为对象进行解剖,分析了不同油藏类型在不同井控程度下含油面积、有效厚度的选值精度及其对探明地质储量的影响,指出对油藏的总体地质认识是决定探明地质储量计算中井控程度的关键因素,相同的井网对不同类型油藏的探明地质储量控制程度不同。确定探明石油地质储量计算合理的井控程度,必须在搞清油藏类型、油水分布规律和储层纵横向分布规律的基础上进行。
In order to calculate proven reserves accurately and decrease exploratory risk as much as possible,well control degree must be re-searched.According to the value of well control degree during proven reserves calculation in the new reserve standard,the effect of value precision of oil-bearing area and net pay on the proven reserves under different well control degree was analyzed in the typical structural and lithologic oil reservoirs in Shengli Oilfield.It points out that the general geological understanding was a key factor of determining the well control degree,and the same well pattern had different control degree on the proven reserves for different reservoirs.So,ascertaining the rational well control degree for calculating proven reserves should be based on the re-search of the oil reservoir types,oil and water distribution,and lateral and vertical distribution of reservoir formation.
