摘要
长庆油田庄73区块长3油藏产液能力为873 m3/d,是合水油田最大的整装高产区块。通过分析地层矿物,对比注入水型配伍性及采油井含水高低,分析管壁、温度等影响因素,总结出该区油井井下结垢的原因。同时,结合油田开发部分情况,浅析结垢对油井的危害,并提出一些防垢的举措及建议。
Fluid production capacity in Chang 3 reservoir of Zhuang 73 block in Changqing Oilfield was 873 m3/d, which was the biggest high-yield block in Heshui Oilfield. By analyzing reservoir minerals, comparing compatibility of injecting water and water cut of product well, and analyzing influence factors, such as thickness and temperature, reasons of oil well scaling were summarized. Meanwhile combined with information of oilfield development, harms of scaling for oil wells were analyzed, and solutions and advices were put forward.
