摘　　要：近年来,松辽盆地常规油气资源接续不足,非常规致密油气资源勘探开发逐步增加,但是受限于致密油地质埋藏及储层发育特点,钻井过程中出现了不同程度的问题,制约了钻井高效施工。针对随钻仪器故障率高、水基钻井液地层适应性差等问题,开展随钻测量仪器稳定性和致密油钻井液体系优化两项技术研究与应用,形成高质高效的钻井工程技术系列,为致密油薄储层经济有效开发提供支撑。In In recent years,the conventional oil and gas resources in Songliao Basin are insufficient,and the exploration and develop-ment of unconventional tight oil and gas resources are gradually increasing.However,due to the tight oil geological burial and reservoir development characteristics,different degrees of problems have appeared in the drilling process,which restricts the efficient drilling construction.In view of the problems such as high failure rate of the while-drlling instrument and poor formation adaptability of water-based drilling fluid,the research and application of the stability of the while-drilling instrument and the optimization of tight oil drilling fluid system have been carried out to form a series of high-quality and efficient drlling engineering technologies,which provide support for the economic and effective development of tight oil thin reservoirs.
