| 摘 要： | 针对低渗透油田普遍生产压差大、气油比高的特点 ,提出了多相流油井气相流入动态关系式的解析方法。利用数值模拟技术 ,获取了长庆靖安油田长 6储层生产初期的流度函数分布 ,并求取了相应的油、气、水相的流入动态关系式。将此关系式的计算结果与实际生产数据进行了对比 ,结果证实IPR曲线解析方法在该区有较好的实用性与适应性。该方法克服了以往在油井产能评价中仅关注产油能力而忽略了可能严重影响生产的产气问题。

| Abstract: | The method for solving dynamic relational expression of inflow performance relationship (IPR) for gas phase in oil well is presented from the Wiggins works. In practice, the gas production dynamics of oil well is often ignored though it is a base of production management for gas driven wells. The inflow funtion distribution of original production of Chang 6 reservoir in Jingan oilfield of Changqing area is obtained. Some relational expressions of inflow dynamics of oil phase, gas phase and water phase are solved. The result of calculation is compared with that of experienced relationship commonly used and the field data. The practicability and adaptability of analytical IPR are proved. |
