Design and Application of Deep Sand Firming Formula in Unconsolidated Sandstone
Abstract:
The backing sand can affect oil production by entering the borehole with formation fluid during the development of unconsolidated sandstone.In view of the backing sand problem,we developed a new antiswe-lling and sand inhibiting agent NTW-1.In-door evaluation of the performance indicated that it had both antiswelling and sand inhibiting abilities and a better effect than other common sand inhibiting agents and clay inhibitors by 10.5% and 65.6% in average,and it could be used easily and economically in the field.A new idea of deep sand firming was proposed according to reservoir sanding mechanism,and a new formula developed on the basis of the composite agent NTW-1.The system could enhance the binding force between backing sand and framework sand,and inhibit the migration of deep backing sand,and reduce sanding room.The success rate and life of sand controlling were enhanced by 8.8% and 37.3%,respectively,and the oil production rate was increased by 46.2%.
