An elementary introduction to formation protection technology—taking A 23 well in Erlian basin as an example.;

Formation damage in the production of oilwater wells is analyzed, and a comprehensive laboratory evaluation method for identifying the mechanism of the formation damage and measures of formation protection is advanced.

It’s meaningful that the basic laboratory of formation protection and the completion application research have been researched aimed at characteristics of the reservoir, for example, it’s with low permeability and high salinity, contents of both clay and colloidal bitumen are high.

Analysis and knowledge of reservoir protection in drilling, Shengli Oilfield;

As an important area of exploration and development,reservoir protection technology has met with much recognition in LunGu block.

This paper presents and summarizes reservoir protection technology and measures during well completion applied in PingHu Oil and Gas Field, including evaluating formation sensitivity,well completion fluid system, lab study of clean brine completion fluid,optimizing design plan of perforation and operationmeasures.

The authors briefly introduced its application and significance in the stidy of clay mineral, its application in the evaluation of cardonate and clastic rock reservoir features and qualities,its application in oil/gas reservoir protection and oilfield production, and its new fruits in the other hydrocarbon research fields.
