STUDY ON STAGED TESTING AND FRACTURING TECHNOLOGY OF SAIPING-1 WELL

In study of staged testing and fracturing technology of Saiping-1 well in Changqing Oilfield,the self-locating and oriented perforating units are designed,the fracture number and technological parameters are selected optimally,the liquid plug technique is developed,and the wellbore isolation is realized successfully.Applying the said technologies,4 stages perforating,testing and fracturing are successfully operated,and obvious results of increase in production are obtained.It provides valuable experience for the horizontal well development of very low permeability reservoir.
