Description
Technical field
The present invention relates to the leakage stopping technology field during geological drilling, oil gas drilling and Science Drilling, in particular to one
Kind leak stopping delay cross-linked gel and preparation method thereof.
Background technique
Formation leakage is the common issue frequently encountered in the probing such as metallic ore, oil gas, underground heat.Formation leakage not only causes
A large amount of wastes of mud are significantly increased drilling cost, can also bring the drilling accident of a series of complex, influence drilling efficiency.It is right
In severe mud losses such as large fracture, Caves, conventional pons hematoma is difficult to form the occluding body of sufficient intensity around pit shaft, blocks up
It is lower to leak one-time success rate, and the method can not be implemented under the conditions of slim-hole, small annular space.And cement slurry leak stopping is usually because logical
Road is lost greatly and can not play a role or be diluted and can not be solidified by underground water, and leak stopping is caused to fail.Crosslinking polymer is solidifying
As one of chemical plugging technology common in petroleum drilling engineering, when leak stopping, is not limited by leakage channel for glue leak stopping, is polymerize
Object and crosslinking agent mix and flow regime under cross-linking reaction occurs, and be detained to be formed in drop ply there is three-dimensional net structure
Viscoelastic body is to realize the purpose of leak stopping.Thus, crosslinking polymer gel leak stopping can be further improved leak stopping adaptability and
