油藏脱气流体PVT数据恢复

PVT DATA RECOVERY OF RESERVOIR DEGASSED LIQUID

油藏流体PVT分析中常取得脱气的流体样品。对脱气的流体样品PVT分析数据进行处理,获得未脱气时的油层流体性质,使无效样品变为有效,一个可行的办法就是将脱气样品的PVT分析数据,依不同的规律,恢复到原始地层条件下的PVT数据,这种数据才能应用于油气藏勘探开发中,实践证明此方法是成功的。

Liquid samples of oil reservoirs collected for PVT analysis were often degassed. How to process the PVT analysis data of the degassed liquid samples in order to obtain the properties of the undegassed reservoir liquid and to make the uneffective samples effective? The answer is to recover the PVT data of the degassed samples to the original formation condition according to the different regulations. The recovered PVT data can be used in the exploration and develop- ment of the oil and gas reservoirs. Practice showed that this method is successful.
