Abstract
The water control process of chemical baffle is a common and effective means to solve the water coning problem in bottom aquifer reservoirs, while the sensitivity and optimization studies of baffle parameters are the key to the success. In order to figure out the sensitivity of chemical baffle parameters on the production performance and enhance the purposefulness of the optimization, respectively 6 sets of schemes were designed for the radius, thickness, permeability and longitudinal position of the baffle for a high water cut directional producer in a strong bottom aquifer reservoir offshore China. Through the flow field simulation of water cone morphology and water drive streamline, combining with production performance analysis, the influence of baffle parameters on controlling water coning and expanding water drive sweep coefficient was analyzed from the aspects of water cone shape evolution, water cone strength, and water streamline density & range. Based on water cone radius and feasibility of measures, the baffle radius with significant sensitivity was optimized. The results show that on the effect of water control and oil increment, the baffle radius has a significant impact, permeability is relatively significant, thickness has an impact but not significant, and longitudinal position has an impact but there is a turning point. Taking into account both oil increment and oil increment per unit chemicals, it is recommended to inject 550 m3 chemicals to the target well from perspective of economy and feasibility. Thus, the radius of the baffle is about 28 m, which can completely cover the water cone bottom. This study synthesizes the flow field simulation of water cone & water drive streamline and production performance analysis, and a systematic study on the parameters of water control chemical baffle is conducted. Not only does it obtain parameters’ sensitivity, but it also analyzes the mechanism of water control and oil increment by chemical baffle from the perspective of flow field. It has certain significance for the optimization and evaluation of water control measures by chemical baffle for bottom aquifer reservoirs.
