随着大庆油田难采储量动用力度的加大，开展了体积压裂水平井开发实验。实验效果较好，但目前对压裂效果没有经济有效的评价手段。由于体积压裂后，压裂改善区与原始地层渗流能力相差较大，形成“压裂改善边界”。文章利用现代产量递减分析方法在判断边界距离方面的优势，通过计算压裂改善体积，评价水平井体积压裂效果。
隨著大慶油田難採儲量動用力度的加大，開展瞭體積壓裂水平井開髮實驗。實驗效果較好，但目前對壓裂效果沒有經濟有效的評價手段。由于體積壓裂後，壓裂改善區與原始地層滲流能力相差較大，形成“壓裂改善邊界”。文章利用現代產量遞減分析方法在判斷邊界距離方麵的優勢，通過計算壓裂改善體積，評價水平井體積壓裂效果。

With the developing of difficult-to-recover reservoir,we carried out the experiment of horizontal well volume fracturing in Daqing oilfield. The effects were good, but at present there is no good means to evaluate the level of the effects, because of the“the improved for-mation boundary by fracturing between fracturing zone and original formation” after volume fracturing. In this paper,taking the advantage of its production decline analysis technology in judging the distance to the improved formation boundary,we evaluated the level of the effects of horizontal well volume fracturing by caculating the volume of the improved formations.
