Objective The Chinese Altai as a key part of the Central Asian Orogenic Belt is characterized by numerous outcrops of Paleozoic granitoids and minor mafic plutons (Fig. 1a). It is widely accepted that Devonian ridge subduction played an important role in the tectonic evolution of the Chinese Altai. However, Carboniferous magmatism related to ridge subduction has received little attention. Moreover。

Optimizing the Diameter of Plugging Balls in Deep Shale Gas Wells

Ltd.Wuhan430205China Fracturing Acidizing co.pany Downhole Operation Company of Chuanqing Drilling Engineering Co.Ltd.Chengdu610213China

Deep shale gas reserves that have been fractured typically have many relatively close perforation holes. Due to theproximity of each fracture during the formation of the fracture network, there is significant stress interference,which results in uneven fracture propagation. It is co.mon practice to use “balls” to temporarily plug fractureopenings in order to lessen liquid intake and achieve uniform propagation in each cluster. In this study, a diameteroptimization model is introduced for these plugging balls based on a multi-cluster fracture propagationmodel and a perforation dynamic abrasion model. This approach relies on proper co.sideration of the multiphasenature of the co.sidered problem and the interaction force between the involved fluid and solid phases. Acco.dingly,it can take into acco.nt the behavior of the gradually changing hole diameter due to proppant co.tinuousperforation erosion. Moreover, it can provide useful information about the fluid-dynamic behavior of the co.sideredsystem before and after plugging. It is shown that when the diameter of the temporary plugging ball is1.2 times that of the perforation hole, the perforation holes of each cluster can be effectively blocked.
