SEW油层套管在模拟井条件下的射孔试验
Perforation Test of SEW Oil Casing Under Simulated Well Conditions
摘要
Abstract
In order to judge the perforation performance of oil casing intuitively,the SEW(hot stretch-reducing electric welding) casing pipe was tested under simulated well conditions in oilfield perforators inspection center. The test results showed that J55, N80Q,P110,BSG-80TT and BSG-110TT,5 kinds of steel grade SEW oil casing,its perforating performance was fully in accordance with the industry standard of China National Petroleum Corporation. The percentage of fractured hole was 0%,the crack length was 0 mm,and the outer diameter expansion was small after perforation,which was better than the perforation performance of the other casing plants in domestic and abroad.关键词
