Study On Log Evaluation Method In Damingtun Sha ? Region Of Liaohe Oilfield

Our country successively in the western tarim,daqing,liaohe,henan,tight sandstone hydrocarbon flow,SSCMTS confirmed our tight sandstone reservoir of oil and gas resource potential is enormous.Liaohe oilfield in the early seventy s was put forward and began to strengthen the exploration of dense sandstone in search of new oil and gas reservoirs,such as double deck and cattle in the area of dense sandstone exploration has now begun to take shape.At present,the scope of the tight sandstone oil and gas exploration work is expanded year by year,with the deepening of the work of tight sandstone reservoir type,reservoir,reservoir,cap,etc have a certain understanding.And effectiveness of tight sandstone oil and gas exploration in this area,reservoir types,single well production is high,the tight sandstone in the area has great potential for oil and gas exploration,thus expanding the scope of the tight sandstone exploration,strengthen and improve the recognition of tight sandstone oil and gas is necessary.This article has introduced the reservoir quality index and fracture porosity,and connecting with the array induction,imaging and array acoustic logging new technology to the reservoir properties of the three dense sand reservoir,oil and gas,etc.Finally,combine the work area of reservoir geological characteristics of research,and established the q to establish standard of oil and gas layer identification and reservoir parameter interpretation model,on the basis of logging secondary fine processing and interpretation,research work area of oil and gas distribution regularity of water.Application method of this paper,first of all,the evaluation of secondary exploration Wells in the studied area,comprehensive analysis of logging data and test data shows that in the forward tectonic belt high well before the new 601-about the line and his four period of sand body is favorable reservoir sand,poor reservoir property,and better lubricity,belongs to low porosity low permeability reservoir.Type oil accumulation of tectonic lithologic reservoir,oil and gas distribution regularity of control by forward large fault and lithologic characteristics,in the high position near the forward large fault and lithologic oil and gas enrichment.L257 on four paragraphs to block sand shale,local sand conglomerate,siltstone,thickness is200-500 meters,commonly under paragraphs to thick massive tuffaceous breccia,shallow gray glutenite,characterized by fine sand,thickness is 300-600 meters,commonly containing clastic rock for sand contains four main sand body.Drill through the study of blocks of the 185 well logging data of four secondary interpretation evaluation,established the oil and gas layer interpretation of the electrical standards,improve the interpretation precision.
