ABSTRACTS SOME SUGGESTIONS OF IMPROVING WELL CONTROL TECHNOLOGY LEVEL

According to the occur of well blowout and treatment of dangerous well,the paper analyzed the several phases from overflow to well blowout,emphasized the technical points of prevention well blowout,i.e.recognition overflow,well shut-in and well killing links.The paper analyzed the moment of truth of discover overflow based on the features of overflow,and presented the adopted well killing methods because of reintegration downhole pressure balance.At the same time,the relative merits of typic well shut-in methods were also analyzed.
