Cementing Practice in High Pressure Gas Wells with KQ??A Aerated Cement

??This paper presents a new cementing method with KQ??A aerated cement which provides a new way to solve the problem of gas leakage caused by "weightlessness" of cement slurry. Through cementing practice in sever gas wells of South Sichuan Petroleum Mine, Sichuan Petroleum Administration (i.e. Sha??9, O??1, Bao??61, Ba??14, Tonglan??5, Lu??14, Long??40??1 etc.), it isproved that this method can prevent gas leakage at the well head or fluid inter. connection among zones in the gas wells with high pressure and multizone reservoirs respectively, and the cementing quality has been obviously improved.
