| 摘 要： | 本文利用细管法研究了J区块原油与CO2最小混相压力,为J区块低渗透油藏CO2驱注入压力选择提供依据,应用Anton Paar MCR301旋转流变仪测定了该区块脱气原油粘温性。研究结果表明,原油的粘度对温度非常敏感,随温度升高而大幅度降低。该油藏原油与CO2最小混相压力是22.39MPa,结合该区块地面、地下实际情况,J区块油藏注CO2驱替可以实现混相。

| Abstract: | Minimum miscible pressure of CO2-crude oil in J-block has been researched by slim tube method in this paper,which would provide the basis for the selection of injection pressure in CO2 flooding of low permeability reservoirs for J-block.Moreover,the viscosity-temperature characteristics of degassed oil in this block has been determined by AntonPaar MCR301 Rotational Rheometer.The results of the study show that the viscosity of crude oil is quite sensitive to temperature,which decrease sharply with increasing temperature.Minimum miscible pressure of CO2-crude oil in this reservoir is 22.39MPa,and injecting CO2 into the reservoir of J-block can achieve miscible flooding combining with the actual situation of surface and underground in this block. |
