摘要
鉴于姬塬油田硫酸钡锶垢防治难度较大,通过对油田注入水样品、储层岩芯样品和油田水样品的测试分析,对其进行了结垢成因方面的研究。结果表明:成垢阳离子主要来源于储层岩石,主要通过长期的水-岩反应进入地层水中,成垢阴离子主要来源于注入水,当地层水与注入水相混合时便形成了硫酸钡锶垢。
In view of the situation that the barium/strontium sulfates scaling is difficult to prevent in Jiyuan oilfield,reasons of the barium/strontium sulfates scaling have been researched according to the analysis of injected water,reservoir core and oilfield-water.The research results show that: scaling cations mainly derive from the reservoir rock,they enter into the formation water by means of long-term water-rock reaction;scaling anions mainly originate from the injected water;the barium/strontium sulfates scaling can be formed when the formation water meets the injected water.
