摘　　要：针对准噶尔盆地超深低渗透油藏储量规模落实但单井产量较低的难题,研究了低油价常态下的开发对策。近年来压裂、酸化等储层改造措施总体效果较差,但庄106井超深低渗透油水同层酸洗后产液能力提高17倍,已增油1421t,表明低投入的实用开采技术可以获得较好的增产效果。目前国外超深层油气开发技术投资费用偏高,应着力拓展稀油。针对新春采油厂超深井单井产能低、大型储层改造由于费用高而难以规模应用的难题,注水吞吐等经济开发思路值得深入探讨和实践。准噶尔盆地中部深层储层渗透性差且裂缝不发育,吸水差。在保证注水水质前提下,不必高压注水,可以考虑温和注水。In the light of ultra-deep low-permeability reservoir reserves scale implementation but lower single-well production of the horizontal well in Junggar Basin, we discussed the development strategy under normal conditions of low oil prices. General stimulation technology of fracturing and acidification was poor in effect, but liquid production capability after pickling of oil-water layer of Well Zhuang 106 ultra-deep low-permeability reservoir rose by 17 times, and oil production was increased by 1421t. It indicated that low-cost recovery technology could obtain better stimulation effect. At present, we should focus on thin oil development due to the higher investment of foreign ultra-deep oil and gas recovery tech- nology. In view of low single-well productivity and difficulties in wide application of large-scale stimulation for high cost, cyclic water injection and other economic development thoughts are worth of further study and practice. Deep reservoirs in central .lunggar Basin are characterized by poor permeability, no development of fractures and poor water absorption. On the premise of ensuring injection water quality, we do not have to inject with high pressure and can take moderate water injection into consideration.
