摘要

The Jurassic oil reservoir in Wuqi is a typical bottom water oil and gas reservoir. The overall law of vertical distribution of oil and water is that oil layer, oil-water same layer, poor oil layer, water layer and dry layer are intertwined and distributed, most of which are low porosity and low The reservoir with poor permeability requires fracturing to start production. There is a problem that the bottom of the fracture is too close to the water layer or directly presses through the water layer, resulting in high water cut or clear water, resulting in the loss of productivity of the oil well, and this problem affects the development effect of the Jurassic. the biggest problem. In this paper, aiming at the shortcomings of the technology of reducing the construction displacement and controlling the rise of the subsidence agent, a new plugging agent is proposed. The plugging agent has the characteristics of water blocking and oil permeability. Significant results have been achieved initially.
