Analysis Of Reservoir Characteristcs In The Typical Blocks Of Daqingzijing Oil Field

Daqingzijing oil field has been found out as a complex reservoir in Jilin oil field inrecent years, which is lithology dominated represented for low holes, low permeabilityreservoirs. As the major "battlefield" for Jilin oil field Increasing the production, Daqingzijingoil field has a over100million tons reserve scale.Daqingzijing oil field located in Qianan county of Jilin province, north from Qianancounty is about30km, south from Changling country is about70km. The northwest part of itis Haituozi oil field, the northeast part is connected with Qianan oil field, and the southeastpart is Dalaoyefu oil field. The regional structure located in the middle of Changlingdepression, which lies in the central concave field of southern Songliao basin,Daan—Honggang terrace is in the northwest, and the Huazi terrace lies in the eastern part.it's difficult for us to develop and put the reservoir into production,because the reservoir havecomplicated geological features,which brings big challenge to allocate practice jobs,evaluatereservoir and exploit oil-field. So carrying out integrated,systematic research for Daqingzioil-field reservoir characteristics is urgently needed.On the basis of the analysis of regional geological rules,this paper make full use of thecomprehensive evaluation technology,which combining geology,sesmic and logging todevelop reservoir characteristics research on the typical block of Daqingzijing area. Mainlyuse fine structure interpretation technology to carry out reseach on the structurecharactertistics,draw up the high-precision top fault and microstructure effectively. Adoptmicrofacies technology to complete quan4member to yao1member located in Daqingzijingarea microfacies job and draw up sand body distribution of each sand set. Use5700loggingseries to identify sandstone and oil-water layers, and take advantage of fluid identification todivide oil-water layers exactly. At last,we analyse oil reservoir distribution characteristics,oiland water distribution,the type of reservoir,and then make sure the favorable oildomain,deppen the cognition of reservoir,try our best to combine a point with an area,andprovide the basis for accelerate oil-field development and reserves research.
