摘　　要：旨在深入分析定边采油厂东仁沟区块大斜度定向井固井技术的难点,如井眼轨迹控制、水泥浆性能要求、套管下入等方面的技术难点,并提出优化井眼轨迹控制、优化水泥浆体系、优化套管下入工艺、减小摩擦力等措施,以期提高油田的油井开采效率和稳定性,保障油田的可持续开发,并为其他类似低渗透油田固并提供参考。This study aims to conduct an in-depth analysis of the technical challenges faced in the cementing technology of directional wells with large inclination angles in Dongren沟block of the Dingbian oilfield,such as wellbore trajectory control,cement slurry performance requirements,and casing lowering technical difficulties.Measures as optimizing wellbore trajectory control,optimizing cement slurry systems,and optimizing casing lowering technology to reduce friction are proposed.This is expected to improve the efficiency stability of oil well exploitation in the oilfield,ensure the sustainable development of the oilfield,and provide a reference for similar low-permeability oilfields.
