Abstract:
Zhangdian Oilfield is one of the major production block in Henan Oilfield,and most wells are drilled directionally according to the reservoir distribution tendency.To improve the perforation completion efficiency and single well production,studies were conducted on improving the perforation technologies,focusing on the existed problems,perforation parameter optimization,structure modification of perforation gun and field application.Field applications showed this technology is effective for improving perforation completion efficiency and single well production.
