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...

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。

By a comprehensive study of all kinds of data (separatelayer well testing, temperature well logging,radioactive isotopes traces,coring……etc.),it is assumed that in each hydrofracturing job,a system of fractures (instead of a single one) parallel to bedding planes and stretched horizontally are produced.Each fracture is in the form of a pan-like pattern with the well axis as its centre, and distributed unevenly.The fact that promissing results are generally abtained in fracturing job in thick oil zones...

By a comprehensive study of all kinds of data (separatelayer well testing, temperature well logging,radioactive isotopes traces,coring……etc.),it is assumed that in each hydrofracturing job,a system of fractures (instead of a single one) parallel to bedding planes and stretched horizontally are produced.Each fracture is in the form of a pan-like pattern with the well axis as its centre, and distributed unevenly.The fact that promissing results are generally abtained in fracturing job in thick oil zones proves that the above assumptions are correct.

本文通过综合各种资料(如分层测试,井温测井,放射性同位素示踪法,钻井取心等),阐明大庆油田的压裂裂缝形态特点是以沿着层理面形成的水平裂缝为主,且一次压裂一般都形成多条水平裂缝带,水平裂缝以井轴为中心盘状向外发展,平面上呈不均匀状。目前,选择性压裂技术,已大量用于厚油层层内挖潜,并取得了较理想的效果,证明了水平裂缝的结论是正确的。

Fracturing fluid is one of the most important elements for ensuring successful fracture operations. It must be viscous enough and capable of carrying sands deep into the fractures created in the reservoirs. With the fullest exploitation of the power of fracturing units, fracturing fluids should be used with the minimum damage to the reservoirs to achieve the maximum benefit. Wide differences of geological and physicochemical properties exist between reservoirs of different permeability. Application of many of the conventional fracture fluids suitable for reservoirs with high permeability may bring harm to reservoirs of low permeability. The authour has proposed some of the essential requirements in the choice of fracture fluids for lowpermeability reservoirs that are technologically rational and economically feasible.
