摘　　要：在能源资源开发过程中必然会在复杂底层进行钻井,其可以为能源开采方面的具体井位选择提供可靠的数据支撑,但在复杂底地层低密度钻井过程中较为容易发生的一项问题就是压裂性漏失,对此空心玻璃微珠的选择是尤为重要的。通过比对和评价空心玻璃微珠性能,基于分散稳定性以及密度和流变性、滤失性等基础上针对空心玻璃微珠对钻井液性能造成的影响进行了有效的测试,并且在优化实验的背景下获得了一种新型低密度钻井液体系,这种新型钻井液体系主要是以一种空心玻璃微珠为减轻剂得以实现的,其显著的特点就是流变性和滤失性能较好,同时又具备良好的分散稳定性性能。During the development of energy resources,drilling will inevitably be performed in complex stratum,which can provide reliable data support for specific well location selection in energy extraction.However,one of the problems that often occur during low-density drilling in complex stratum is fracturing leakage.So the selection of hollow glass microspheres is particularly important.The performance of hollow glass microspheres was compared and evaluated.Based on the dispersion stability,density and rheology,and fluid loss,the effects of hollow glass microspheres on drilling fluid performance were effectively tested.Under the background,a new low-density drilling fluid system was obtained.This new drilling fluid system was mainly realized by using a hollow glass microsphere as a mitigating agent.Its significant feature is better rheology and filtration performance.It also has good dispersion stability.
