姬塬油田长2低阻油藏玉裂地质特征及其改造技术研究

Research of Fraction Geology and Technique of Chang 2 Low-resistance Formation in JIyuan Oilfield

本文首先从压裂地质角度出发，对影响姬塬油田长2低阻油藏储层改造的地质因素进行分析，从而认识到油层底水、低阻是该油田储层改造的技术难点，并根据储层的地质特征，从改造角度对储层进行分类。并针对各类储层的不同特征提出了相应的改造思路，从而使姬塬油田长2储层改造更具针对性，通过现场试验取得了良好的改造效果。

Geology factors affecting Chang 2 low-resistance formation reconstruction in JiYuan Oilfield are analysised from fraction geology. Then it is realized that oil bottom water and low resistance are technique difficulty. And reservoir is classified from reconstruction according to geology features of oil effective thickness, bottom water and double layer. The reconstruction with Chang 2 formation developed more efficiently and obtained fine result, forming relative reconstruction idea according to different feature of various reservoir.
