Abstract
Flu id o ften has leakage in produc ing zone o f high wa ter cut produc tion w ells during the rem ed ia l and stimu la ting operations. In orde r to so lve th is problem, a new wa terso lub le tem po rar ily plugg ing ag ent is prepared . This agen t is p lastic irregu la r pa rtic le and can be d isso lved in w ater in 3 days, so it can p lug producing zone w ithout fo rma tion dam age. It can also be carr ied w ith HPAM or guar so lution in fie ld app lication. In the forty- four tests, 13 w ells are successfu,l 33 of them get m ore production than the production before.
