Disccussion on Deep Horizontal Well Drilling Techniques
Abstract:
Through researches on deep horizontal well drilling technology and field experiments in about 10 wells in the Western Oilfieldes,a series of deep horizontal well drilling techniques including optimizing engineering design,hole trajectory control,safty drilling and drilling fluid system is obtained and several drilling records of horizontal well drilling is seted.The production rates of the most testing wells are over 1000t/d,the social and economic benifits are remarkable.
