The Dense Oil Comprehensive Research And Exploration Target Optimization Of Leijia Region

Dense oil refers to clip in or close to the density of the high quality source sequence in the clastic rock and carbonate reservoir,without mass formed by the long distance migration of petroleum accumulation,there is no natural capacity,through large-scale fracturing technology to form the industrial capacity.The physical properties of dense oil line for ground air permeability is less than 1 mD,underground pressure permeability is less than 0.1 mD.Liaohe ray home area since the 70 s in exploration.Already in the zone,multi-port test well industrial flows.Since high 34 did well for industry,but the production management of the research work has been in general.As use of the exploration degree of gradually improving and developing constantly improve,08 since the region has deployed more than ten Wells,and have 7 ancient 2 motif,ancient 14,15,77,84,84,ray ray ray ray 88 Wells in four segments are good oil and gas shows.But with the continuous exploration and development,only a tiny part of proven reserves of the report into development,most well characterized by high initial production,fast production decline,don’t do engineering characteristic of the oil.With the deepening of the dense oil research at home and abroad.Liaohe oilfield company decided to set up 2011 liaohe ray home four period of dense oil and gas research group,there are several joint research unit,the thunder home four period of dense oil sand for reasonable and effective exploration and development research.The team from has been established using,dense oil theory study on the "seven" ray dense oil conducted in-depth research,analyzes the lithology,Du Gutai there are five main lithologic reservoir.High reservoir lithology is similar to Du Gutai reservoir,mainly for argillaceous dolomite and dolomitic mudstone is given priority to,grain of crumbs YunYan area of development.The porosity,permeability is much less than 1 predicted the distribution range of composite area of about 300 km2.For,physical property,oiliness character of hydrocarbon source rock characteristics,stress is also analyzed.
