Publish Date: 10 September 2015

Abstract

Abstract

Gansu Yangshan mining area geological structure is complicated, broken strata alteration strong, multi layer leakage, drilling leakage loss is a common phenomenon.On the basis of in-depth study of the mechanism of formation leak-age, the polymer gel plugging technology is explored and tested.In the construction, polymer gel plugging is not limited by the leakage passage, which can enter the space of cracks and holes, and ultimately achieve the purpose of sealing leakage. In ZK2232 field application shows that the use of polymer gel plugging agent and other inert bridging agent can be used to solve the leakage of the drilling process, and the effect is better.
