低渗透油田地低渗透性小、油层孔隙小等特点决定了其开采难度,为了确保低渗透油田地保持正常生产水平,我们需要对地质进行改造。通过小井眼钻井技术、水力压裂增产技术、水平井技术和超前注水技术等的应用来确保低渗透油田地的生产效益。本文就对低渗透油田地的地质特点和各项技术的应用进行研究,并提出相应措施及自己的见解。
The low permeability of low-permeability oilfields and the small pores in oil reservoirs determine the difficulty of exploitation. To ensure the normal production of low-permeability oilfields, we need to reform the geology. Through the application of slim hole drilling technology, hydraulic fracturing stimulation technology, horizontal well technology and advanced water injection technology, the production benefit of low permeability oilfields can be ensured. This paper studies the geological characteristics of low permeability oilfields and the application of various technologies, and puts forward corresponding measures and their own opinions.
