摘　　要：吐哈油田三塘湖盆地卡拉岗组、石炭系火成岩储层具有岩石成份复杂、基质物性差、天然裂缝发育、粘土矿物含量高、地应力差异大等特点,给火成岩储层的压裂改造带来了诸多难题,火成岩储层的压裂增产改造技术国内外可供借鉴的经验很少。通过深化认识储层地质特征,研制与储层相适应的压裂液配方体系,研究支撑剂组合加入方式、压裂改造工艺技术以及助排方式等,形成三塘湖火成岩储层的压裂工艺技术,在现场取得了很好的应用效果。The carbonic igneous rock reservoir in TuHa oilfield has the characters of complex rock constituent, poor physical properties, natural fracture growth, high content of clay mineral, as well as great difference of geostress, which caused many difficulties in the fracturing reforming of igneous rock. There are few experiences of fracturing production increase technology. We reformed the fracturing technology for igneous rock reservoir by learning the reservoir geology characters, working on the fracturing fluid suited to reservoir, researching the propping agents and fracturing technology, etc.. The application effect was remarkable.
