The Establishment Of Tarim Oilfield Cementing Process Standardization System

The geology in tarim oilfield is very complex for most wells there are deep even ultra-deep wells with high temperature and pressure. Moreover, lithologic character there is various and some petroleum conduct large scale of sulfur. However, when talking about cementing, tarim employs standards from API/ISO/GB and SY, which belong to the basic requirements of the casing, cement requirements and lack of specificity, can not meet the needs of the harsh environment of the Tarim Oilfield.In this article, on the basis of the research standards of the cementing process at home and abroad, combined with the actual situation of the Tarim Oilfield, establishmented the conventional casing and casing process standardization system, the special Swagelok and casing process standardization system. According to the actual needs of the Tarim Oilfield, establishmented the conventional cementing process standardization system, two stage cementing process standardization system, the end of the cementing process standardization system, cementing plug process standardization system, squeeze cementing process standardization system. At the same time, this article also explained the deep wells, high temperature wells, high pressure wells, deviated wells, horizontal wells, long seal the well cementing process key technologies to form the Tarim Oilfield special well cementing process standardization system. For meet the production needs of the Tarim Oilfield, combined with "SY/T6592-2004"and the Tarim Oilfield cementing the actual situation, establishmented the Tarim Oilfield cementing quality evaluation standardization system.
