With the recent proliferation of horizontal drilling specifically targeting oil bearing reservoirs, high strength acid fracturing treatments in the Beaverhill Lake formation in northern Alberta have dramatically increased in both product volume and number of treatments. The Beaverhill Lake formation is a limestone/calcareous shale that produces a desirable mid to high API sweet crude oil. Although the crude oil typically has a low concentration of asphaltenes, the oil is very sensitive to acid and/or iron induced asphaltene precipitation. As the acid strength increases and ferric iron is dissolved into solution, it becomes increasingly difficult to chemically prevent the asphaltenes from precipitating. Acid blends designed to prevent asphaltene precipitation also tend to be very emulsifying with the crude oil, therefore a careful balance between anti-sludge additives and non-emulsifiers must be found. This paper will describe the chemistry of surfactants that can be used to prevent asphaltene precipitation as a result of acid/oil contact. Specifically, a comparison of anionic versus cationic surfactants will be given, describing both the benefits and detriments of using these in acid blends. A discussion of the change from vertical well completions in the Beaverhill Lake formation to horizontal multizone completions will be presented. As a result of this change in completions, the desired properties of the acid blends have changed noteably. The final results of a comprehensive laboratory study to optimize cost and performance of the acid blends will be presented. A review of field case studies comparing formation response to anionic and cationic acid blends will also be presented.

随着最近针对含油储层的水平钻井的激增,在阿尔伯塔北部的Beaverhill Lake地层中,高强度酸压裂处理的产品数量和处理数量都大幅增加。Beaverhill Lake地层为石灰岩/钙质页岩,可生产理想的中高API低硫原油。虽然原油通常具有低浓度的沥青质,但原油对酸和/或铁引起的沥青质沉淀非常敏感。随着酸性强度的增加和三铁在溶液中的溶解,用化学方法防止沥青质沉淀变得越来越困难。为防止沥青质沉淀而设计的酸混合物也容易与原油发生乳化,因此必须在抗污泥添加剂和非乳化剂之间找到一个谨慎的平衡。本文将介绍用于防止因酸/油接触而产生沥青质沉淀的表面活性剂的化学性质。具体来说,阴离子表面活性剂和阳离子表面活性剂的比较将给出,描述在酸性混合物中使用这些表面活性剂的好处和坏处。讨论了从Beaverhill Lake地层的直井完井到水平多层完井的变化。由于完井的这种变化,酸共混物的预期性能发生了显著变化。将介绍一项综合实验室研究的最终结果,以优化酸混合物的成本和性能。还将介绍比较阴离子和阳离子酸混合物对地层反应的现场案例研究综述。欲订购全文,请访问https://doi.org/10.2118/164087-MS TECHNICAL paper
