Research on the Matching Technologies for Optimized and Fast Drilling in Dagang Oilfield
摘要
Abstract
It is difficult to speed up drilling in deep and ultra-deep wells in Dagang oilfield mainly because of the poor dril-lability in conglomerate of Guantao formation and compact mudstone of Shahejie formation;abnormal high temperature and high pressure in deep oil and gas reservoir and the characteristics of high density and the high viscosity of the drilling fluid. To explore the matching technologies suitable for optimized and fast drilling of deep and ultra-deep wells in Dagang oilfield, the research was carried out based on the drilling case of Binshen 24-5-27.By the optimization of drilling fluid systems, application of drilling with fine pressure control and compound drilling with effective PDC bit +screw motor, this project was completed with a drilled depth of 4510m, drilling cycle of 36 days and average penetration rate of 11.56m/h.The re-search shows that the effective drilling cycle is mainly profited from the improvement of ROP and ordered connection of pro-duction organization.Compared to the history index well of the same block, the ROP is increased by 15.27%, organizing time is shortened 31.68%in the second and the third sections, and the drilling cycle was shortened 18.78%.This matc-hing drilling technology could provide the engineering technology support for effective exploration of deep oil and gas reser-voir in Dagang oilfield.关键词
