摘　　要：准噶尔盆地西北缘百口泉地区二叠系油藏为典型的砂砾岩油藏,其储层物性和孔喉结构均较差,属较差孔喉结构的低孔、低—特低渗较差储层。油藏的产能特点为产能较低,且变化大,整体采收率较低。产能影响因素主要与储层物性特别是渗透率和试油工艺有关,前者主要体现在裂缝和孔喉结构的影响,后者主要是不同压裂措施的影响。提高此类油藏产能有效的方法和手段主要为油藏研究和工程技术两个方面,即寻找断裂带附近的裂缝发育区和具较好物性储层以及采用大型的现代压裂改造措施。The Permain reservoirs of Bai kou quan area in northwestern margin of Junggar basin are the typical glutenites.Reservoir physical properties that belong to low pore and low-extra low permeability and pore throat structure are both comparative poor The characters of oil reservoirs are low and unstable productivity and low recovery.The main influences of productivity are permeability which reflects in fracture and pore throat structure and production testing technology which mainly embody different fracturing measures.The efficient methods and means to improve the reservoir productivity are reservoir research which finding the fracture development zones that near fault zone and the better physical properties reservoirs and engineering technology that using large size modern fracturing modification measures.
