Abstract

Pai 10 West Oilfield, located in the west of Chunguang Oilfield, is a typical medium and high permeability thin oil lithologic reservoir, with serious sand production problems, and the traditional mechanical sand control technology has a short validity period, which cannot meet the long-term development needs of this block. In order to solve this problem, a high-strength self-emulsifying sand fixing agent system (HCS) based on epoxy resin was developed in this paper, and its performance under complex geological conditions was verified by experiments. In the experiment, the performance of the sand fixing agent was comprehensively evaluated by sand particle sieve analysis, sand filter performance test, bottomhole environment simulation, anti-aging and anti-erosion experiments. The results show that the sand fixing agent can effectively form a uniform cladding layer, significantly improve the consolidation strength of sand particles, and maintain excellent compressive strength and permeability in high temperature, high pressure and complex downhole environment, with excellent erosion resistance. In addition, the sand fixing agent exhibits excellent anti-aging ability and can maintain high strength and stability over a long period of time. The research results of this paper provide an innovative technical scheme for efficient sand control in Pai 10 West Block, and also provide a reference for the sand production problem of similar high-permeability reservoirs.
