RFT资料在多井储层评价中的应用

THE APPLICATION OF RFT DATA IN MULTI-WELL RESERVOIR EVALUATION

本文以东濮凹陷马厂地区为研究工区着重论述重复式地层测试(RFT)资料在多井储层评价中的应用。利用压力资料可定性、定量判断储层的渗透性,估算渗透率值可用于油层有效厚度标准研究,压力随深度梯度变化转换为密度变化来了解流体性质、确定油水界面,从而验证测井多井解释结论。研究表明,应用效果明显,解释结论得到试油试采证实,解释符合率提高,研究成果有助于研究工区油藏综合评价,部分成果已用于油田生产。

With the Machang area of the Dongpu depression as the study area, this pa-per mainly discusses the application of the Repeat Formation Test (RFT) datain multi-well reservoir evaluation. Pressure data may be used to make a qualitativeand quantitative estimation of the permeability of reservoirs. The permeabilityestimate may be used to study the effective thickness standard of oil reservoirs.The transformation of the variation of pressure with depth into the variation ofdensity with depth can help to understand the properties of fluids and determinethe oil-water interface, thus verifying the conclusion of multi-well logging inter- pretation. Study indicates that the application yields marked good results. Theconclusion of the interpretation has been verified by formation and productiontests and the conformity rate of the interpretation increases. The research resultsare conducive to the comprehrensive reservoir evaluation of the study area, andsome of the achievements have been applied in oil production. Finally the paperpoints out that the application of RFT data has a vast prospect.
