饶阳凹陷复杂砂岩储层产能测井预测方法
|
摘要
饶阳凹陷砂岩储层物性较差,原油黏度差异大,异常高压普遍发育,简单的产能预测模型难以满足测井精细评价的需要。基于生产测试数据和油-水两相渗流理论,深入分析了储层物性、原油黏度及饱和度、地层压力等对产能的影响,建立了压力校正的变黏度产能测井评价方法,实现了油、水产能的有效分离,为储量评价、施工方案设计等提供了依据。研究表明:储层的渗透性对产能具有决定性作用,油、水产量与渗透率成正比;原油产量与原油黏度成反比,在稠油层中影响更为明显,对水的产量影响较小;储层的异常高压也是影响产能的特殊因素,异常高压层油、水产能明显偏大。
Sandstone reservoirs of Raoyang sag are characterized by poor physical property,great differences in crude viscosity and wide development of abnormal high pressure.The simple capacity prediction model is unable to satisfy the requirement of accurate logging assessment.Based on production test data and the oil-water two-phase flow theory,this study deeply analyzed the influences of reservoir physical properties,crude viscosity and saturation as well as formation pressure on capacity,and created the viscosity-varying capacity logging evaluation method with pressure correction,thus achieving the effective separation of oil-water capacity and providing the basis for reservoir evaluation and construction planning.The results show that the production capacity is dominated by the permeability of reservoir and proportional to oil-water production capacity.The production capacity of oil is inversely proportional to crude viscosity with more significant influences on heavy oil,but less impact on water production.The abnormal high pressure of reservoir is also a particular factor to influence production capacity,where oil-water production capacity is significantly large.
