摘要

For low permeability bottom water reservoir fracturing, it is easy that hydraulic fracture penetrate into aquifer zones and lead to problematic production of water when potentially productive zones are located a few meters above water or the interlaminar stress contrast is not big enough. Swellable particle plugging agent as a new profile control agent has been applied widely and achieved good results. In order to ensure the performance of bottom water fracturing with swellable agent, the shut-off capacity and intensity on pore has been tested by physical model experiments and a new mathematic model for artificial barrier has been proposed. It can provide some reference on reasonable application of swellable plugging agent in bottom water reservoir fracturing. The application results in Luliang oilfield show that swellable plugging agent can effectively seal water layer and achieved a significant increase of oil production.
