    Abstract
  • Presently the consumption of oil and natural gas has increased sharply, while the development of conventional oil and gas is reducing, this makes the development of unconventional oil and gas, such as oil and gas from deep wells, offshore wells and shale gas wells more and more imminent. In the development of unconventional oil and gas, the sealing integrity of cement sheath may probably be damaged, leading to oil and gas channeling in the annulus which imposes great hindrances and risks to oil and gas production and causes great economic losses. Epoxy based workover fluid can be used to replace cement slurry in workover job to solve the problem of inability of cement slurries to penetrate micro pores. Epoxy based workover fluids have many compositions and poor adaptability. To simultaneously satisfy the needs of workover operation in different formations with different temperatures, facilitate the transportation, storage and deployment of field operation, and improve the economy of workover and promote the industrialization process, a workover fluid was developed with liquid aromatic amine (LAA) as the main curing agent. The performance of the workover fluid was evaluated, the thickening performance and the kinetics of the workover fluid, and the compressive strength and micromorphology of the set product were characterized. The results show that the LAA system has initial consistency of less than 30 Bc, thickening time that is adjustable between 2 h and 5 h, compressive strength that is greater than 20 MPa at various temperatures, and it is able to satisfy the needs of workover operation at temperatures between 30 ℃ and 90 ℃.
