| 摘 要： | 为了减少钻井对环境的污染等问题,大庆油田在中浅层探井钻井设计过程中有针对性的进行了优化设计,主要从井身结构设计入手,同时对钻井液设计、钻具组合设计、固井设计一系列的设计方案制定了相应的预防措施和改进。改进后的井身结构设计不仅提高了钻井施工过程中的井控安全性,而且较好地保护了环境,特别是对深层地表水起到一定的保护作用。研究了储层潜在损害方式,分析了钻井保护技术的作用原理、应用情况与取得的效果,经过2010年已钻的15口中浅层油气深下表层探井的后效跟踪,包括整个钻井过程和后续的采油过程,均未发现出现污染地表水和周围环境的现象,较之以前石油钻井更加环保,更加符合日益发展的社会对环境保护的要求,这对保护人类赖以生存的自然环境具有重要意义。

| Abstract: | Optimized design was made on middle-shallow stratum exploration well for environmental protection well drilling in Daqing oilfield.Starting with the design of casing program,related preventive and improving measures were formulated for the designs of drilling fluid,drill assembly and well cementing.The improved casing program increased the safety in drilling construction with environmental protection,especially for deep water.The reservoir potential damage was studied;the action principle,application and the effect of well protective technology were analyzed.The after-effect tracking showed that there was no water and environment pollution in the 15 oil and gas wells drilled in 2010 with deep surface casing in middle-shallow stratum. |
