大庆 F 区块挥发性油藏流体特征及影响因素分析
Volatile Oil Reservoir Fluid Characteristics in F Block, Daqing Oilfield and Affecting Factors Analysis
摘要
Abstract
The separation oil and gas component and physical property are analyzed with gas chromatography.The component of initial oil in place in F block is obtained by using PVTsim.The changes of PVT parameters of oil in F block is studied and the effect of separation stages and choke size change on the fluid composition and physical properties is analysized.The results are listed as follows:the initial oil in F block has a characteristic of high content of light hydrocarbon,low density,high shrinkage and high gas-oil ratio,and the change of pressure has a greater influence on PVT parameters.Compared with black oil,reservoir fluid has a strong sensitivity on separation stages.When multi-stage separation is applied,initial oil in place e has a characteristic of high shrinkage,small degassed amount and high oil production.When small choke is applied,the pressure before choke is high.So light component is more likely to be mined.关键词
