The effective distance of acid penetration along a fracture is an important parameter for acid fracturing design and treatment.Up to now, it has not yet been taken into account at home and abroad that the decreasing acid concentration and the increasing reaction products influence the effective mass transfer of hydrogen ions in the flowing acid reacting with carbonate rocks.

The effective distance of acid penetration along a fracture is an important parameter for acid fracturing design and treatment.Up to now, it has not yet been taken into account at home and abroad that the decreasing acid concentration and the increasing reaction products influence the effective mass transfer of hydrogen ions in the flowing acid reacting with carbonate rocks. In our research, we have found that the influence of the common ion effect on the effective mass transfer coefficient of hydrogen ions is considerable. It is an important factor to be considered.By means of reaction of flowing hydrochloric acid of various concentrations with Yang Xin limestone of Permian age from Sichuan, we have got some curves which express the relationship between the transfer coefficient with the partially spent acid concentration and the flowing Reynolds number.With the help of mathematical statistics an experience equation expressing dimentionless relation of them has been obtained. When we substitute it into the convection-diffusion equation and solve the latter, the distance of acid penetration can be claculated. In the calculation the change of acid concentration and the common ion effect are taken into account. This distance may be also estimated by superposing the results of calculating section by section.

裂缝中流动酸液的有效穿透距离,是压裂酸化施工设计和预测增产效果的一个重要参数。迄今为止,国内外的研究者,在解决这一问题时,均未考虑酸—岩流动反应过程中,酸浓度下降和反应产物浓度升高对氢离子传质速度的影响。我们的研究发现,同离子效应对氢离子有效传质系数的影响较大,是一个不可忽视的重要影响因素。 本文在系统试验研究的基础上,给出不同浓度的盐酸和四川二迭系阳新灰岩反应时,氢离子有效传质系数与余酸浓度的关系曲线,用数理统计的方法,给出了无因次氢离子传质系数与无因次余酸浓度及流动雷诺数函数关系的经验方程。将此经验方程代入并求解变系数的对流扩散偏微分方程,即可获得考虑酸浓度变化和同离子效应时的酸液有效穿透距离的计算方法。也可用分段迭加计算法来近似计算这一距离。

在酸性气田的开发过程中,湿硫化氢引起的钢材应力腐蚀开裂从而造成管材、容器。阀门……的突然破坏是保证顺利开发和安全生产的重大障碍。本文通过对中40井阀门破坏的事故分析,利用金相、硬度、断口及表面腐蚀产物的检验结果,说明了井口节流阀阀座的开裂是一起典型的硫化物应力腐蚀破坏。文章还对引起破坏的原因进行了分析,并提出了建议。
