油基钻井液用氮杂石墨烯的研制与应用OA北大核心CSTPCD
The Development and Application of Nitrogen-Containing Graphene for Oil-Based Drilling Fluids
对川西海相雷口坡组地层破碎、水平井后期托压严重、井壁失稳突出等问题进行分析发现,现用油基钻井液体系的封堵润滑性不能有效满足施工需求.为提高油基钻井液的封堵润滑性,通过分子结构设计,采用氮掺杂改性与熔盐法相结合的方式,制备出氮杂石墨烯,并通过热稳定性、分散稳定性、XRD、红外光谱、粒径分析等手段表征其热稳定性、分散性、结构、基团和粒径大小.实验结果表明,当氮杂石墨烯在现场油基钻井液中的加量为 0.5%时,高温高压滤失量降低率达到 76.2%,润滑系…查看全部>>
The marine facies Leikoupo formation in the west of Sichuan Province is a broken formation,in the later stage of horizontal drilling,it is frequently unable to exert weight on the drill bit,and borehole wall instability is another problem that haunts the drilling engineers.Analyses of these problems show that the oil-based drilling fluids presently in use have plugging capacity and lubricity that are unable to satisfy the needs of operation.To improve the pl…查看全部>>
