中文摘要:
      流型调节剂是用来改善钻井液流变性的处理剂,通过增黏提切使钻井液具有较高的动塑比和较好的剪切稀释性。但随着大位移井、大斜度定向井及深水、超深水井等技术的发展,复杂地层中钻井液的流变性还是易出现黏度、切力不足,性能衰减过快,甚至失去悬浮与携带能力的问题,尤其是大位移井和复杂井经常出现井眼清洁能力不足的问题。该文主要按钻井液类型:典型钻井液用流型调节剂、恒流变钻井液用流型调节剂和其他钻井液用流型调节剂综述了现有钻井液用流型调节剂的研究进展和应用情况,。首先对不同钻井液用流型调节剂的增黏提切能力、耐温性、环保性和价格优势进行比较和评价,随后对流型调节剂未来的发展方向提出了建议,以期为相关研究提供参考。
英文摘要:
      Rheology modifier, which mainly to increase the shear force and viscosity is a key additive to improve rheology of drilling fluid so that the drilling fluid has a higher dynamic plastic ratio and better shear dilution. With the development of ERD, high-angle directional well, deep water well, ultra-deep water etc., it is difficult for drilling fluids to have effective rheology in complex formations which often occurs problems such as insufficient viscosity and shear, excessive degradation and even loss the capacity of suspension and carrying. Especially, the problem of insufficient wellbore cleaning often appeared in the large displacement wells and complex wells. This article mainly introduces the research progress and application of existing rheology modifiers for drilling fluids. According to the type of drilling fluid, it is divided into: rheology modifier for typical drilling fluid, rheology modifier for flat-rheological drilling fluid and rheology modifier for other drilling fluid. Firstly, the author compare and evaluate the ability of increase viscosity and cutting, temperature resistance, environmental protection and price advantage of different rheology modifier for drilling fluids and then proposed suggestions for the future development of rheology modifier in order to provide information and references.
