Publication number: 20170015889Abstract: A synthesis method for degradable material(s) (DM) which can be used in oil and gas field operations. The method involves using two, three, four or five polymer and chain extenders, including poly glycolic acid (PGA), polycaprolactone (PCL), polylactic acid (PLA), poly (butylene succinate) (PBS) and poly(3-hydroxybutyrate) (PHA), to synthesize a “resin alloy” through the melt mixing reaction method, which can be used in oil and gas field operations. The proposed DM can be prepared into flake, powder, granules, and ball shapes, or by one of the pure PGA, PCL, PLA, PBS and PHA, into flake, powder, granule and ball shapes, which can be further used in all kinds of operations (drilling, well completion, workover and acidizing fracturing) in oil and gas fields, such as temporary plugging to protect a reservoir, temporary plugging of perforation holes, construction intervals, etc. The DMs are fully degradable and cause almost no damage to formations.Type: ApplicationFiled: July 13, 2016Publication date: January 19, 2017Inventors: Fujian ZHOU, Zhipeng ZHOU, Min WANG, Jie ZUO, Cuihong ZHOU
