摘要:
压力衰竭速度是影响稠油溶解气驱泡沫油生产的一个关键因素。为定量描述压力衰竭速度对泡沫油现象的影响,实验选取了4组不同压力衰竭速度进行实验。研究不同压力衰竭速度下稠油衰竭开采中的采收率、产油量、生产气油比以及实验压力的变化。通过实验发现稠油溶解气驱过程中出现明显的泡沫油阶段,且压力衰竭速度越大,泡沫油拟泡点压力越小,泡沫油阶段越长。随着压力衰竭速度增加,采收率增加,生产气油比减小,油藏压力递减变慢。
Abstract:
The pressure depletion rate is a key factor of influencing foamy oil production of dissolved gas drive in heavy oil. In order to quantitatively describe the effect of the pressure depletion rate on foamy oil,four experiments were carried out under various pressure depletion rates.Under various pressure depletion rates,it was studied carefully on the recovery rate,oil production,gas-oil ratio(GOR),and pressure change in heavy oil depletion.Experimental results show that in the process of the dissolved gas flooding of heavy oil,there is an obvious foamy oil period,the bigger the pressure depletion rate is,the smaller the pseudo-bubble point pressure of the foamy oil is,and the longer the foamy oil period is.It is found that with the pressure depletion rate increases,oil recovery rate increases,the gas-oil ratio decreases,and the reservoir pressure decline slows down.
