油气层早期产能估算新方法

The new estimation method for oil-gas layers′early productivity

利用地化录井分析数据对储集层早期产能进行估算,该文探讨了这种新方法。根据地化热解参数,并结合有关气相色谱资料及相关物性资料,确定产能的主要影响因素,并对照试油结论,建立了产能估算的经验公式和回归方程。通过对辽河盆地不同地区、不同油质的储集层进行产能计算,证明地化方法估算产能是有效可行的,为油气评价与开发提供了重要的参考依据。

The paper approached a new method, in which the reservoir early productivity could be estimated or computed with geochemical logging analysis data. According to geochemical pyrolysis parameters and combining with the related data of gas chromatogram and physical property, the main influence factors of productivity were determined, and referring to oil testing conclusion, the empirical formula and regression equation of productivity estimation were set up. Through conducting productivity estimation for reservoirs of different areas and different oil quality from Liaohe basin, the results proved that the productivity estimation with geochemical method was good and workable, it provided important reference basis for oil-gas evaluation and development.
