In order to make technical reserves for developing gas cap and buffer zone in A Oilfield and explore effective development methods of gas cap reservoir, according to the overall development idea of oil-gas ring, a field test of gas cap injection and polymer barrier development buffer zone in Layer B was carried out in the structural axis of South Block in 2006. The test adopted the development mode of gas cap injection and polymer barrier development buffer zone, that is, the barrier was established by injecting polymer solution at the oil-gas boundary to separate natural gas from crude oil in buffer zone and keep relatively stable. In this paper, the morphological changes during the establishment and maintenance of barriers are found out by means of monitoring.
Key words: Oilfield a / oil invasion and gas channeling / accumulation barrier / pressure / change
