Abstract

Large-displacement high-intensity sanding hydraulic fracturing operations often cause casing perforation erosion and thus temporary plugging failures, exacerbate the unevenness of fracture initiation and expansion, and induce casing damage. In order to clarify the dynamic evolution of perforation erosion and predict perforation diameter, the effects of different types of proppants, the viscosity of sand-carrying liquids, and large sand-passing quantities on perforation erosion rate were experimentally explored in the study. The evolution of perforation erosion and the particle size distribution of quartz sand and ceramsite were analyzed in the experiment and a prediction model for perforation erosion under various fracturing parameters was established. Compared to ceramsite, quartz sand had the more significant effect on perforation erosion and the more serious particle abrasion and fragmentation under the same sand-passing quantity. Increasing the viscosity of the sand-carrying liquid slowed down perforation erosion and made the edge of perforation entrance more uniform. As the sand-passing quantity through the perforation increased, perforation erosion in the initial stage was concentrated at the perforation edge. Then, the inner wall of the perforation was also eroded, but the average erosion rate was reduced. A prediction model of perforation erosion considering multiple fracturing parameters was established based on the principle of fluid similarity. The errors between predicted values and downhole eagle-eye observation values were less than 15 %. The model provides an important basis for the optimization of fracturing parameters and downhole casing strength design.

多阶段水平井压裂过程中套管射孔侵蚀的演变特征和预测模型
大排量高强度加砂水力压裂作业往往会造成套管射孔冲蚀,从而导致暂时性堵塞失效,加剧压裂起始和扩展的不均匀性,诱发套管损坏。为了弄清射孔冲蚀的动态演化过程并预测射孔直径,本研究通过实验探讨了不同类型支撑剂、携砂液粘度和大穿砂量对射孔冲蚀率的影响。实验分析了石英砂和陶粒石的射孔冲蚀演化过程和粒度分布,并建立了不同压裂参数下的射孔冲蚀预测模型。与陶瓷石相比,石英砂对射孔侵蚀的影响更为显著,在相同的穿砂量下,颗粒磨损和破碎更为严重。增加携砂液的粘度可减缓穿孔侵蚀,使穿孔入口边缘更加均匀。随着通过穿孔的砂量增加,穿孔初期的侵蚀集中在穿孔边缘。随后,穿孔内壁也受到侵蚀,但平均侵蚀率有所降低。根据流体相似性原理,建立了考虑多个压裂参数的射孔侵蚀预测模型。预测值与井下鹰眼观测值之间的误差小于 15%。该模型为优化压裂参数和井下套管强度设计提供了重要依据。

期刊介绍: Wear journal is dedicated to the advancement of basic and applied knowledge concerning the nature of wear of materials. Broadly, topics of interest range from development of fundamental understanding of the mechanisms of wear to innovative solutions to practical engineering problems. Authors of experimental studies are expected to comment on the repeatability of the data, and whenever possible, conduct multiple measurements under similar testing conditions. Further, Wear embraces the highest standards of professional ethics, and the detection of matching content, either in written or graphical form, from other publications by the current authors or by others, may result in rejection.
