主　　题：Oil cracking Deep reservoir Controlling factor Gas to oil ratio Diamondoid 

摘      要：The natural cracking of crude oils in deep reservoirs has gained great interest due to continuously increasing depth of petroleum exploration and *** oil compositions and surroundings as well as complicated geological evolutions make oil cracking in nature much more complex than industrial *** far,numerous studies,focused on this topic,have made considerable progress although there still exist some ***,a comprehensive review on crude oil cracking is yet to be *** article systematically reviews the controlling factors of oil cracking from six aspects,namely,oil compositions,temperature and time,pressure,water,minerals and solid organic *** compare previous experimental and modelling results and present new field *** the following,we evaluate the prevailing estimation methods for the extent of oil cracking,and elucidate other factors that may interfere with the application of these estimation *** review will be helpful for further investigations of crude oil cracking and provides a guide for estimation of the cracking extent of crude oils.
