Description
Technical field
It is a kind of molten inert material sealing agent of part theobromine and its preparation side the present invention relates to drilling plugging agent technical field
Method and application method.
Background technology
During Underwell leakage is Oil/gas Well operation process, working fluid such as drilling fluid, cement mortar, workover fluid etc. enter in pit shaft
Underground high permeability zone, hole stratum, natural or induction formation fracture phenomenon.The harm of Underwell leakage：Head of liquid reduction is made
Into blowout；Cause underground bit freezing；Aggravation reservoir damage, influences cementing quality；Extension drilling period, increases cost, severe patient oil
Well is scrapped.As a example by 2003, the whole world is costly up to 800,000,000 dollars for drilling well leak-proof leak-stopping, does not include also being leaked for treatment
Other down-hole accident expenses that mistake causes.As domestic outer portion old area oil gas field tends to exhaustion, drilling well leakage complicated phenomenon will
Can increasingly protrude.
Either in land or marine drilling operating environment, Underwell leakage is all the time common with oil drilling
Problem, especially for the hole condition that leakage is complicated.At present, commonly use sealing agent and solve the problems, such as Underwell leakage, current leak stopping
Agent species is many, according to the composition species point of sealing agent, can be divided into single dose and complexing agent, and when carrying out leak stopping using single dose, it is blocked up
Leakage effect is poor, and the leak stopping performance of domestic compound sealing agent is not good, has much room for improvement.Particularly with the leakage that leakage is complicated
Lose, existing sealing agent is difficult to reach its leak stopping requirement, so as to constrain the raising of leakage complex process efficiency, this turns into restriction oil
One of major technology bottleneck of gas exploration development rate.And the plugging effect of the sealing agent of external import is preferably, but it is produced
Relatively costly, price occupies height, makes the reduction of its cost performance, causes to increase using the leak stopping cost of external sealing agent.
The content of the invention
