合采井产量贡献估算

合采井单层产量贡献是油藏动态分析和油藏数值模拟的基础。目前可用试油、生产测井、地质分析以及油藏地球化学等四种方法进行单层贡献的计算。试油是一种最直接的方法．但成本较高、耗时较长。生产测井是一种定量化程度较高，成本也较高的常用方法。而地质分析基于对油藏的精细了解，是一种耗时较短，成本较低的定性到半定量的方法，广为应用。油藏地球化学方法是一种新兴基于油藏流体的差异，通过对色谱指纹的辨别和对比，进行合采井单层产出贡献的计算方法，该方法成本低、耗时短，但受油藏条件的限制较多。

PRODUCTION ALLOCATION METHOD OF COMMINGLED WELLS

Production allocation is the foundation for dynamic analysis and reservoir numerical simulation.There are four ways including well testing,production logging,geological analysis and reservoir geochemistry to allocate production of each layer in the commingled wells.Well testing is a direct way which always needs much more time and costly expense.Production logging is a common way of higher ability for quantitative analysis,but its cost is also expensive.Geological analysis,as a half quantitative way,based on the detailed knowledge of the reservoir,is widely used beause of consuming very short time and low cost.Geochemistry method is a new method developed in recent years.Although it has advantages of short time consuming and low cost,its use is limited due to many reservoir factors.
