It is targeted at the Wufeng Formation-Longmaxi Formation shale reservoir.
The drilling depth is nearly 6000 meters, and the horizontal section is over 1500 meters long.

.

On the basis of summarizing the preliminary results of the first 7 stages of fracturing construction and testing, the exploration branch continued to use "multiple stages and few clusters + equal aperture perforation + domestic integrated slippery water + large liquid volume and large displacement + double temporary plugging (temporary ball-throwing plugging) +Temporary Blocking in Fractures)" fracturing concept, after the completion of the last 23 stages of fracturing construction, we strive to increase the reconstruction volume and form a complex network of fractures to enhance the effect of fracturing reconstruction
