Current situation and development of offshore completion technology

Rational selection of optimal well completion methods is critical in fully exerting oil well potential and effectively developing oil fields.In this paper, the application of advanced theologies to sand control and intelligent completion of offshore oil and gas fields is introduced.To meet the requirement of offshore exploration and development, the development tendency of offshore completion technologies is proposed.Research and pilot test are conducted on marginal oilfields, deep development with high temperature and high pressure, and heavy oil exploitation.Meanwhile, combined with field application of well completion technology, independent innovation and absorption of completing tools are supposed to be carried out to realize independent property right transformation.
