    Abstract
  • For the development of heavy oil reservoirs in offshore oil and gas fields, the fish bone spur branch well technology was adopted, and the completion fluid in the branch well filling process cannot be gel-broken, so that gravel pack operation cannot be effectively implemented in the branch well. Therefore, an intelligent gel breaking completion fluid system was developed. Using the completion fluid of xanthan gum modified by succinic anhydride to solve the problem. Controlling the addition of succinic anhydride and reaction time to determine the substitution degree of succinic ester group. Alcohol hydroxyl was replaced by succinic anhydride in xanthan gum, it can reduce the ability of inhibiting oxidative free radicals, reduce the stability of xanthan gum, and solve the problem about difficultly breaking completion fluid. To achieve the purpose of intelligent gel breaking the gel-breaking time of completion fluid was regulated by optimizing the dosage of NaOH, Na2CO3 and antioxidant. Breaking time of the completion fluid prepared by XC-2 was controlled within 3-8 days. Breaking time of the completion fluid prepared by XC-1 was controlled within 5-14 days. The recovery values of reservoir permeability were all greater than 89% before and after the gel breaking of completion fluid prepared by XC-1 and XC-2, which had good protection effect to the reservoir.
