摘要:
气测录井能及时发现油气显示,定性识别油气水层,预报井涌、井喷和气侵,是油气发现及储层流体判别的重要方法,但利用其与测井资料综合识别储层流体黏度的研究较少。通过对L油田钻井过程中大量油层的气测录井组分比值与原油API°相关性研究,回归建立预测原油API°的经验公式,避免了气测测量误差和单位不统一的问题。同时,利用本区已有的原油API°与原油黏度关系式,可快速预测油层地面原油密度和地层原油黏度,方法简洁、实用,不仅可节约化验分析费用,还能为射孔生产等快速决策提供依据。
Abstract:
Gas logging can predict kick,blowout,and gas invasion as well as qualitatively identify oil,gas,and water layers. It is a crucial technique for finding oil and gas and identifying reservoir fluids. There are,however,few studies that use it with data logging to fully identify reservoir fluid viscosity. An empirical formula for predicting crude oil API° is established by regression by studying the correlation between the gas logging component ratio and crude oil API° in a large number of oil layers during the drilling of the L Oilfield. This method avoids the issues with gas logging measurement errors and unit inconsistency. The surface crude oil density and formation crude oil viscosity can be predicted quickly utilizing the established correlation between crude oil API ° and crude oil viscosity in this area. The approach is simple and useful,and it can reduce the cost of laboratory analysis while also serving as a foundation for quick decisions about production-strategy.
