摘要
针对珠江口盆地珠一坳陷油层产能预测方法少且定量化程度低等问题,基于FLAIR录井资料,采用回归拟合的研究方法,优选产能预测敏感参数,通过计算油层产能指数,建立了适用于该区域的油层产能预测模型。研究结果表明:平均FLAIR校正油指数与产能正相关性更高,能够代替含油饱和度预测油层产能;利用油层的平均渗透率、平均有效孔隙度、平均FLAIR校正油指数及有效厚度计算的油层产能指数能够准确预测油层产能。在实际应用中建立的新模型预测结果与实际产能符合度更高,取得了较好效果,为勘探开发提供了重要的技术支持。
Aiming at the problems of few methods and low quantification degree of oil reservoir productivity prediction in Zhu-ⅠDepression of Pearl River Mouth basin,the research method of regression fitting based on mud logging and well logging data is used to optimize the sensitive parameters of productivity prediction,and the reservoir productivity index is calculated.Finally,a reservoir productivity prediction model suitable for this area is established.The research result shows that:the average FLAIR corrected oil index has a higher positive correlation with productivity,and it can replace oil saturation to predict reservoir productivity;The reservoir productivity index calculated by the following four parameters:average permeability,average effective porosity,average FLAIR correction oil index and effective thickness can accurately predict the reservoir productivity.In practical application,the predicted results of the new model are in better agreement with the actual production capacity,and good results have been obtained.It can provide important technical support for exploration and development.
