利用液面推算油层静压方法初探

胜坨油田进入特高含水期后,开采难度日益加大,各种动态监测技术的综合运用显得尤为重要。油井压力的录取是油田开发重要的动态监测手段,压力资料是确定油藏合理注采比、制定注采调整方案的重要依据。在分析传统的推算静压方法的基础上,探索出不停井用利动液面推算静压的新方法。只要取得油井动液面或套压资料,就可以应用该方法推算油层静压,减少高产井关井造成的产量损失。

Method of using fluid level to calculate oil reservoir static pressure

oduction is more and more difficult and utilizing every kind of dynamic monitoring technique comprehensively looks more important when Shengtuo oilfield entered extra high water cut period. To gain oil well pressure is the important dynamic monitoring tool for oilfield recovery, and the pressure data is the foundation of defining reasonable injection-production ratio of oil reservoir and of working out injection -production adjustment scheme. Based on analyzing traditional method of calculating static pressure, a new method that uses working fluid level of oil well (it does not needclose oil well) to calculate the static pressure was put forward. As long as working fluid level or casing pressure could be measured, this method could be used to calculate the static reservoir pressure. It can reduce the production loss due to well shutdown in high-production rate well.
