本报告叙述了CT3-6润滑剂活性组份制备和配方研究、中型放大试验及润滑剂综合性能室内评定试验和现场应用试验结果,提出了该润滑剂质量、技术性能指标。实验室数据指出,该剂有很好的热稳定性,不起泡,抗温,抗盐钙污染,对加重泥浆有一定降粘切作用,流变性良好。现场试验说明,在聚晶金刚石钻头钻进中,由于它表现了良好的降摩阻性能、高的膜强度以及防卡性能,延长了钻头使用寿命,达到了提高钻速、降低钻井费用的目的,是一种适于聚晶金刚石钻头配套钻井液的新型润滑剂。
This report describes the preparation and formulation studies of the active components of CT3-6 lubricant, the medium-scale amplification test, the comprehensive evaluation of lubricants indoor test results and field application test results, and puts forward the lubricant quality and technical performance indicators. Laboratory data indicate that the agent has good thermal stability, non-blistering, temperature resistance, salt-resistant calcium contamination, mud viscosity has some viscosity-cutting effect, good rheology. Field tests show that in polycrystalline diamond bit drilling, because of its performance of good resistance to friction, high film strength and anti-jamming performance, prolonging the service life of the bit, achieving the purpose of increasing the drilling speed and reducing the drilling cost , Is a new type of lubricant suitable for polycrystalline diamond bit drilling fluid.
