Abstract:

To reduce pore pressure transmission and enhance shale bore stability,a new patten blocking anti-sloughing drilling
fluid additive humic acid-aluminum(HA–Al)was developed. Pore pressure transmission test in shale results show that HA–Al
has better performance to reduce pore pressure transmission in shale than poly alcohol and sodium silicate. It took 20.0 h or so for
1 MPa pressure to transmit through shale after interacting with HA–Al,which was much longer than that before interaction,
which was about 1.5 h. By optimizing and combining HA–Al and polyamine,a high performance blocking drilling fluid
system was developed. The system has good rheology,filtration,inhibition,anti-pollution and anti-temperature performance
with NaCl concentration more than 8%or CaCl2 concentration more than 1.0%or drilling mass concentration of cutting powder
more than 8% and with temperature higher than 150 ℃ and less than 180 ℃.
