[Abstract]:As an important resource, petroleum plays an irreplaceable role in the national economy. At present, the development of high pressure and low permeability oil wells will become an important growth point of recoverable reserves. However, because of the particularity of exploitation difficulty in high pressure and low permeability reservoirs, it brings a series of new problems and challenges to test tools and downhole tubing string. In order to ensure the reasonableness and success rate of the construction process, it is necessary to optimize the oil test string and test tools of high pressure and low permeability deep wells. Based on this background, the mechanical analysis and technological research of downhole tubing string in low permeability layer have important engineering application value. Development of some testing tools for high pressure and low permeability wells. The mechanical analysis model of oil test string in high pressure and low permeability wells has been established. The mechanical analysis has been carried out under three working conditions: down-down, up-lift and unseal, and fracturing. The results show that the three working conditions all meet the intensity requirements.) some low cost and easy to operate liquid discharge methods that meet the requirements of low permeability oil and gas fields are studied. Select the water conservancy pump drainage technology as the low-permeability layer discharge method to carry on the construction. 4) in view of the high temperature and high pressure low permeability well sealing layer, optimizes the cement slurry formulation, forms the ultra-deep well ash injection sealing layer technology, optimizes the high temperature and high pressure differential bridge plug sealing technology, This paper studies the sealing technology of bridge plug and cement plug, which can realize the completion of pipe string once in the process of bridge plug sitting, sand filling, ash injection and seal checking, and achieve the purpose of long term plugging in downhole. A series of technical research on high pressure and low permeability well will be carried out. In the actual production process, the rationality of the selected pipe string structure and design tools, the correctness of the string mechanics analysis and the feasibility of the technological process are verified by an example well.
