Development and Application of Elastomers for Packers of Petroleum-Extracting Industry
Composition of elastomers (EP) for waterswelling, low temperature resistant, and thermoresistant packers (WP) were developed. WP are developed for the service under bed water of different mineralization (M) so compositions of EP specialized for individual wells of concrete water M. Dependence of swelling of EP on the temperature and M were obtained under laboratory tests. Results for developed and import EP are compared. Hermetic sealing and selfrecovery of WP of developed EP are shown under stand tests. Durability of WP KVART was confirmed by tests in specialized laboratory. Technical characteristics of WP KVART are of the same level as that of import WP and the cost is 2-3 times lower. The use of WP KVART decreases the flooding of wells of high flooding on 29 % (from 99,0 to 70 %) and increase the oil output of the well on 2-3 tones per day. Results of the work are patented according the rules and provided full-value importsubstitution.
