It opens, new leakage occurs；If reducing drilling fluid density, head of liquid, which declines, is excessively not enough to balance gas-bearing formation, and gas can be without control
System ground enters pit shaft and causes blowout.It statistically sees, same deposit of spray leakage is generally present in fractured reservoir, and can also result in storage
Layer injury, blowout out of control, drilling period extends and cost is significantly increased, and even results in scrapping for whole mouth well.
At present, leak stopping kill-job and pressurization sealing are to solve spray leakage with the important technical deposited, and plugging formula is preferred
It carries out, such as casting bed leaking stoppage experiment, aperture plate leaking stoppage experiment, tested often by conventional plugging material evaluation experimental
There is no consider influence of the gas intrusion to leaking stoppage experiment result in gas-bearing formation, therefore cause the plugging material type preferably gone out in journey
The needs of live blocking construction can not be fully met with the adaptability of the plugging formula of formation.
