Ultra Deep Well in Xinjiang **High adaptability for monitoring ultra-deep Wells and harsh surface conditions


The terrain conditions in Xinjiang region are poor, and the common Gobi gravel surface structure will cause the grounding resistance to rise, thus affecting the transmission and reception signals.


The Sichuan Basin, ground resistance is about 500 - 2,500 Ω, while the Xinjiang area is about 3,000 - 5,000 Ω.
Increase the number of aluminum plates buried at the transmitter end, and organize the water tanker to irrigate with salt water to ensure that the grounding condition of the transmitter end is good and the strength of the transmitting signal is guaranteed.


The maximum length of fracturing fluid is 115m, and the total stimulated area is 8,090m2.


Twelve main fractures are generated around the wellbore, and the dominant direction of fracturing fluid is 160-340° (NW-SE), followed by 40-220° (NE-SE). Fracturing fluid mainly enters the pores along the dominant direction and expands rapidly.
