陕北长9储层增油控水增产措施研究

Study of Increasing Production Measure to Increase Oil and Water Control in Chang9 Reservoir of Shanbei Areas

陕北地区长9储层埋藏深、物性差,油水关系复杂,储层改造难度大。通过对长9储层压裂地质特征的分析研究,总结长9储层的改造难点,有针对性的开展以增油控水为目的增产措施研究,取得了较好的效果,实现了深层低渗底水油藏的有效评价。

Chang9 reservoir of Shanbei areas is the formations of deep burial,poor petrophysical properties and complex relationship of water and oil,making it difficult to be developed.By research and analysis of fractured geologic characteristics in Chang-9 reservoir,the difficulties of reservoir stimulation are summarized up,study of production increasing measures targeted to increase oil and water control are carried out correspondently,a good effect has been achieved,and the effective evaluation of the bottom water in the deep low-permeability reservoir has been realized.
