对建南气田储层改造效果的认识

Understanding on Tome Reservoirs Reconstructed Effects in Jiannan Gas-field

建南气田属于低孔隙度-低渗透率型气藏,储层改造是提高气井产能的有效手段。建南气田早期勘探阶段储层改造措施主要是常规酸化,改造效果较好。自2001年以来,结合建南气田滚动勘探开发,对开采效果较差的老井进行深度酸化。综合应用胶凝酸酸化与加砂压裂技术在飞三段取得了一定效果。

Jiannan Gas-field is classified into low porosity and low permeability reservoirs. Reservoirs reconstruction is an effective measure for increasing productivities of gas-well. Routine acidifying treatment with better effect is the main reconstruction measure in the early exploration stage. The measure of deep acidification combined with the rolling exploration and development has been conducted in some old gas-wells with poor productive effect since 2001. The integrated application of the technology of gelatinous acidifying and fracturing ＆ sand-filled fracturing in the reservoir of Fei-3 formation has gained effect.
