摘要：【中文】本发明提供一种具有射孔子簇的水平井分段多簇限流压裂方法，具体步骤为：步骤一，确定压裂段内射孔簇数及各射孔簇的位置；步骤二，每个射孔簇位置设置多个射孔子簇，射孔子簇的间距不小于2 m且不超过8 m；步骤三，下入射孔工具在水平井段内既定位置射孔，形成具有射孔子簇的射孔簇；步骤四，进行压裂施工，射孔簇的多个子簇均会起裂并倾向于沿井筒两侧的不同方向延伸，在段内射孔簇位置形成井筒两侧近乎均匀对称的水力裂缝。本发明，利用射孔孔眼的限流效应，裂缝自射孔子簇起裂并分别向水平井筒两侧扩展，从而在每个射孔簇位置形成在井筒两侧近乎均匀对称的水力裂缝。从而能够达到减少无效射孔簇的产生、提高储层改造程度的目的。 【EN】The invention provides a horizontal well subsection multi-cluster current-limiting fracturing method with perforating sub-clusters, which comprises the following specific steps: determining the number of perforation clusters and the positions of the perforation clusters in a fracturing section; step two, arranging a plurality of perforating sub-clusters at each perforating cluster position, wherein the spacing between the perforating sub-clusters is not less than 2m and not more than 8 m; thirdly, putting a perforating tool into the horizontal well section for perforating at a set position to form a perforating cluster with perforating sub-clusters; and fourthly, carrying out fracturing construction, wherein a plurality of sub-clusters of the perforation cluster can be cracked and tend to extend along different directions of two sides of the shaft, and hydraulic fractures which are approximately uniform and symmetrical on two sides of the shaft are formed at the positions of the perforation clusters in the section. According to the invention, by utilizing the current-limiting effect of the perforation holes, the cracks are initiated from the perforation sub-clusters and are respectively expanded to two sides of the horizontal shaft, so that the hydraulic cracks which are approximately uniform and symmetrical on two sides of the shaft are formed at the position of each perforation cluster. Therefore, the aims of reducing the generation of ineffective perforation clusters and improving the reservoir transformation degree can be achieved.
