Reservoirs in the Triassic Baikouquan formation of Mahu sag in Xinjiang oilfield is a typically tight permeable formation. Considering the purpose of the development and comprehensive analysis

by the factory fracturing ideas of zipper fracturing and subdivision cutting volume fracturing by plug fracturing with multi-stages and multi-clusters

we explored and created a factory fracturing method that is used in 2 horizontal wells of 2 000 meters long in well area Ma131 by using pre-acid pretreatment

slick water multi-plug

low damage gel fracturing fluid which is causing a complex net volume on the role of stress interference. 26 and 22 stages fracture were respectively implemented in 2 wells with the

which leads to a good stimulation with the oil yield over 30 tons per day after hydraulic fracturing. The successful study and use of factory fracturing make a good foundation for the later stimulation of Mahu tight oil and provide safeguard for the scale effective development of tight oil in this area.
