【摘要】：介绍了一种模拟评价起泡剂在温度压力下的起泡性和泡沫稳定性的装置,并利用该装置评价了压力、温度、井深段对起泡性和泡沫稳定性的影响规律。室内评价结果表明:在温度压力条件下,压力对起泡剂的起泡性无明显影响,对泡沫稳定性的影响较大,随着压力的升高而更加稳定;温度对起泡剂的起泡性影响有限,对起泡剂的泡沫稳定性在135℃以下影响较小,在135℃以上影响较大,表现为泡沫稳定性随温度升高而降低;井深段对起泡剂的起泡性无明显影响,对于泡沫稳定性略有影响。应用室内评价结果,在T-19井开展了现场试验,获得成功,产气量和产水量增加,油套压差大幅降低,证实了室内评价方法和数据可靠性,可指导现场泡沫排水作业。
[Abstract]:A device for simulating the foamability and the foam stability of the foaming agent under the temperature pressure is introduced, and the influence of pressure, temperature and well depth on the foamability and the stability of the foam is evaluated by the device. The results of the indoor evaluation show that under the condition of temperature and pressure, the foaming property of the foaming agent has no obvious influence on the foaming property of the foaming agent, the effect on the stability of the foam is large, and the foaming effect of the foaming agent is limited with the increase of the pressure, The foam stability of the foaming agent is less than 135.degree. C., and the effect on the foam stability is lower at the temperature of 135.degree. C., and the foaming stability of the foaming agent has no obvious influence on the foaming property of the foaming agent, and has a slight effect on the stability of the foam. The on-site test was carried out in the T-19 well with the result of the indoor evaluation, and the success, the gas production and the water yield were increased, the pressure difference of the oil jacket was greatly reduced, and the indoor evaluation method and the data reliability were confirmed, and the on-site foam drainage operation can be guided.
