Abstract  

What we want to summarize here is a low permeability oil and gas field. After 50years of polishing, those revolutionary technologies branded with low permeability marks. In terms of its contribution, it is such a technical sequence from one row to six: first, oil and gas exploration technology that infinitely approximates the migration and accumulation law of Ordos hydrocarbon sources; The second is the brand-name, customized and service-oriented drilling fluid completion hydraulic fracturing technology; Third, natural fractures are not developed, and artificially created fracturing technology for low permeability oil and gas reservoirs; Fourth, the advanced water injection and pressure boosting development technology of ultra-low permeability oil fields, which is deficient in nature and then compensated by nature; Fifth, the large-scale cluster well technology that low-permeability oil and gas fields must be developed at low cost; The sixth is the horizontal well technology that allows the longest possible well section to lie flat in the oil and gas reservoir. It is these technologies that have exerted their effects on the low-permeability oil and gas reservoirs, resulting in many changes in the low-permeability oil and gas reservoirs in line with people’s wishes. It is these gratifying changes that converge into a continuous flow of oil and gas in Changqing Oilfield.
