Abstract: Production crude oils are analyzed by geofina hydrocarbon meter(GHM).The oils come from different stages in the process of water expelling simulation ex periment. In addition, the change rule of crude oil components is studied. and the internal relations between crude oil components and production degrees are also researched. The experiments indicate that a regular connection is formed between production degree of crude oil and the PV number of fluid.The carbon number range or the peak carbon number of normal alkanes in crude oils shift behi nd and the light/heavy hydrocarbons ratio exists decreasing direction along with the increase of production degree. The another conclusion is proved by experim ent that some isoprenoid alkane molecules are easier to expel from reservoir than the normal alkane molecules of close carbon number because of their column st ructure in space. Therefore, this investigation has practice significance in res earching expelled mechanics from microcosmic points of view and increasing production ratio of crude oils.
