摘要
克拉玛依油田五区南乌尔禾组储层，在近期用胍胶液压裂的几口井中。压裂后产出的原油与压裂前产出原油性质不同：点火不燃、常温下呈棕色胶体状、化验分析困难。原油物性改变的原因来自胍胶压裂液，因此建议减少或不用胍胶液压裂，在目前条件下尽可能用田菁液压裂。
After guar gum fluid fracturing in several wells produced from Wuerhe Formation reservoir in southern District No . 5 of Karamay oilfield, the significant difference in physical preperties of crude oil ensued, which was embodied as follows: noninflammable on ignition, brown colloid at ambient temperature,and difficulty in conventional analysis.These problems arise from guar gum fracturing fluid. Viewing that it is recommended that sesbansia fluid is preferentially used rather than guar gum fluid on fracturing treatment under present conditions.
