There is still no acknowledged dividing standard for low permeability and extra low permeability reservoirs. Scholars from F. U . R and China defined the reservoirs with the permeability less than 50×10 3 μm2 as low permeability reservoirs. The geological characteristics of buried depth of 550~1700 m and air permeability of (1 -40)×10-3 μm2 of the reservoirs in the surrounding Mesozoic basins were carefully discussed to determine the main development index and parameters of well...

There is still no acknowledged dividing standard for low permeability and extra low permeability reservoirs. Scholars from F. U . R and China defined the reservoirs with the permeability less than 50×10 3 μm2 as low permeability reservoirs. The geological characteristics of buried depth of 550~1700 m and air permeability of (1 -40)×10-3 μm2 of the reservoirs in the surrounding Mesozoic basins were carefully discussed to determine the main development index and parameters of well space of 150-200 m, the development mode of supplementing energy on time, one or two sets of development layer series as well as single well productivity of 4 ~ 9 t/d. The analysis and discussion were given from the economic point of view of internal financial benefit and payback period of the investment,etc. . Practice shows that our method and operating way is feasible.

低渗透、特低渗透至今没有一个公认的划分标准。前苏联和国内部分学者将空气渗透率小于50×10~(-3)μm~2的储层称为低渗透。针对我局外围中生代盆地油藏埋深550~1700m,空气渗透率介于(1~40)×10~(-3)μm~2之间等油藏地质特征进行较为详细的论述,指出了在外围低渗透油藏早期开发设计与评价中,确定150~200m开发井距、适时补充能量的开发方式、一套或两套开发层系及4~9t/d的单井生产能力等主要开发指标与参数的探讨方法,并从财务内部收益率、投资回收期等经济评价角度加以分析论证。实践证明,我们确定的方法是可行的。

Ansai oil field is characterized by low Permeability, low pressure, low output and adverse natural conditions, so surface engineering construction of Ansal oil field has great difficulty. A set of production technique and process suitable for extra-low permeability oil field has been developed and a unigue construction mode of surface engineering construction has been established in Changqing Oil Field through scientific research and technical development during oil field exploitation and construction. These efficiently reduce engineering costs and gain considerable economic benefits. The paper describes this production technique and process.
