摘要
Through a lot of logging and logging data analyses, Machang and Madong fractures can be divided into 3 parts which are sequentially upper induced fracture zone, middle closed zone and lower induced fracture zone. The three parts of Machang fractures can result in the gases generated from Carboniferous-Permian coal measures source rocks mainly enriching in the upthrown side of Machang fracture. The three parts of Madong fracture can result in the oils and gases generated from Hegangji Sag mainly enriching in the upthrown side of secondary, west-dip fracture in Machang fracture.
