摘要： 运用气相色谱法对分离油和分离气进行了组成组分及原油物性分析。利用P VT s i m 得到F区块地 层油组成组分, 通过模拟多次脱气实验, 研究了该区块原油的高压物性参数变化及影响其变化的因素, 分析了分离 级数及开采条件变化对流体组成及物性的影响。结果表明, 该区块地层油具有轻烃( C 1~C 6) 含量高、 密度低、 收缩 性强、 溶解气油体积比大的特点; 与黑油相比, 压力变化对P VT参数的影响更大; 油藏流体P VT特征对分离级数具 有强烈的敏感性, 多级分离时, 地层油收缩率较小, 脱气量较小, 产油量较大; 小油嘴开采时, 嘴前压力较高, 原油中 轻质组分脱气相对较少, 采出的原油中轻质组分较高, 轻质组分更容易被开采出来。

Abstract: The separation oil and gas component and physical property are analyzed with gas chromatography. The component of initial oil in place in F block is obtained by using PVTsim. The changes of PVT parameters of oil in F block is studied and the effect of separation stages and choke size change on the fluid composition and physical properties is analysized. The results are listed as follows: the initial oil in F block has a characteristic of high content of light hydrocarbon, low density, high shrinkage and high gasoil ratio, and the change of pressure has a greater influence on PVT parameters. Compared with black oil, reservoir fluid has a strong sensitivity on separation stages. When multistage separation is applied, initial oil in place e has a characteristic of high shrinkage, small degassed amount and high oil production. When small choke is applied, the pressure before choke is high. So light component is more likely to be mined.
