摘　　要：现阶段无论在技术,还是管理层面还未形成地质工程一体化的模式,决策结果缺少地质和工程沟通环节,导致因钻井设备无法大幅度进行轨迹调整或施工参数等原因造成的定向难度大,短期内无法快速实现地质目的,较大影响储层高钻遇率,若超出工程施工最佳安全参数,不仅增加井筒内摩阻系数,还可能对下步完钻测井、套管下入等完井作业带来一定的井控隐患,对整体钻井周期、实施效果及后期油气井开发衔接均有一定程度影响。为此,开展涵盖钻前、钻中和钻后的钻井系统过程中的“地质工程一体化工作流程”的方案设计,强化多专业协同配合探索研究,加快推进地质工程一体化能力建设,打造标准化、规范化运行模式,支撑油气勘探开发增储上产和井筒工程提速提效,对目前钻探行业一体化模式的建立与应用方面,具有一定的推进作用。At present,there is no integrated model of geological engineering in terms of technology and management.The lack of geological and engineering communication links in decision-making results has led to difficulties in directional control due to the inability of drilling equipment to significantly adjust trajectories or construction parameters.This has greatly affected the high drilling encounter rate of the reservoir layer,making it difficult to quickly achieve geological goals in the short term.If the optimal safety parameters for engineering construction are exceeded,not only will the friction coefficient inside the wellbore increase,but it may also bring certain well control hazards to the next completion operations such as drilling and logging,casing insertion,etc.,which will have a certain degree of impact on the overall drilling cycle,implementation effect,and later oil and gas well development connection.To this end,a"geological engineering integration workflow"scheme design covering pre drilling,mid drilling,and post drilling system processes has been carried out,strengthening multi-disciplinary collaboration and exploration research,accelerating the construction of geological engineering integration capabilities,creating standardized and normalized operation modes,supporting oil and gas exploration and development to increase reserves and production,and accelerating and improving wellbore engineering efficiency.This has a promoting effect on the establishment and application of integrated models in the current drilling industry.
