ABSTRACT = {The	 macroscopic	 tar-rich	 coal	 in-situ	 pyrolysis	 (TCISP)	 multi-physics	 simulation	 is	 conducted,	 in	 the	
fractured	porous	zone,	by	coupling	heat	transfer,	fluid	flow,	and	chemical	reaction.	A	novel	TCISP	pattern	of	
gas	injection	between	fractured	zones	is	proposed,	by	treating	the	fractured	porous	zone	as	a	homogeneous	
porosity	gradient	descending	region.	In	this	case,	nearly	11500	kg	of	oil	can	be produced	within	6	months	
from	a	10*10*1	m3	area.	The	influence	of	the	fractured	zone	and	porosity	are	investigated.	Results	indicated	
that	 gas	 injection	 between	 fractured	 zones	 is	 more	 conducive	 to	 rapid	 production,	 compared	 with	 the	
traditional	 case	 that gas	injection	is	in	 the	 center.	 The	 temperature	 field	is	more	 uniform,	 conducive	 to	
maintaining	the	same	reaction	conditions	and	producing	appropriate	products.	Inlet	velocity	has	a	positive	
effect	on	the	increase	of	heat	transfer	rate,	but	is	negative	to heat	transfer	uniformity.	There	is	an	optimal	
inlet	temperature	of	973	K	for	the	fastest	heating	rate.	With	the	increase	of	temperature,	the	heat	transfer	
uniformity	gets	worse.	Increasing	the	height	of	the	fractured	zone	is	beneficial	for	the	heating	rate	and	heat	
transfer	uniformity.},
