白音查干凹陷构造特征与油气关系

管穆兰库国正张放东尹哲()白音查干凹陷是二连盆地内的一个中生界含油凹陷,构造及其发育演化是油气成藏与富集的主要控制因素凹陷的结构类型断裂展布平面与剖面构造样式构造发育演化等与油气富集关系非常密切根据作者多年的研究实践和大量的第一性资料,较全面地论述了凹陷的4种结构类型断裂与构造特征及样式,阐述了它们与油气富集的关系,并提出了下步勘探的方向和建议白音查干凹陷凹陷结构构造特征构造样式油气富集,,,NWW,,(k1ba)(k1bt)(k1bd)(k1bs),(k1ber)[1],,,,1,,,,,,,(1),NEENNENNW3,NEE,,,,,,,,,,,,(1)291217,-,,,1620055FAULTBLOCKOIL&GASFIELD1232004-12-14,,40,,,(457001):,:[phone],,242914163325393612,,Y!,X!,,,,9;,,X!!,[2]22,,,,,972433,,14163912,17,233.13200km2,4,2(3):,;,,,(3a),:,,,(3b),1712320055:,,,,(3c),:,;,,,(3d)33.2,,,,,,,,,,,,,,,,,,,,,,,,,,,[3]4(1),,,(2)4,,(3),,,(4),,4,1,,..,1999,6(2):9~132,,..,1999,6():12~153,,..,1998,5():19~22()1820055123throughtechniquesofbuildingofinitialwaveimpedancemode,lcalibratingofsyntheticseismicsection,waveletpickingandthinlayeridentificationetc,combiningcharactersoftheregion.Desiredresultswithimprovedreliabilityhavereached.KeyWords:Carbonatereservoirs,Loggingconstrainedinversion,Reservoirprediction,Impedance.StructuralFeaturesandItsRelationshipwithHydrocarbonAccumulationinBaiyinchaganDepressionGuanMulan(ExplorationandDevelopmentResearchInstitute,ZhongyuanOilfieldCompany,SINOPEC,Puyang457001,China),KuGuozhengandZhangFangdongeta.lFaultBlockOil&GasField,2005,12(3):1618BaiyinchagandepressionisaMesozoicoilbearingdepressioninErlianbasin.Thestructureanditsevolutionisthemaincontrolfactorforreservoirformationandhydrocarbonaccumulation.Structuretype,faultdistribution,planeandsectionstructurepattern,structureevolutionarecloselyrelatedwithhydrocarbonaccumulation.Itisnarratedinthispaperfourstructuretypesofthedepression,faultstructuralfeatureandpattern,andtherelationshipbetweenthesefactorsandhydrocarbonmigrationandaccumulation.Moreover,thepaperbringsoutsomeadviceandpointsoutfurtherexplorationtarget.KeyWords:Biayinchagandepression,Depressionstructure,Structurefeature,Structurepattern,Hydrocarbonaccumulation.StudyonHydrocarbongenerationSimulativeExperimentandChangingCharacteristicsofOutcomesofSourceRocksintheFourthSectionofShahejieFormationofJiyangDepressionDongBo(ManagementDepartmentofExplorationProject,ShengliOilfieldCo.Ltd.,SINOPEC,Dongying257001,China).FaultBlockOil&GasField,2005,12(3):1921Hydrocarbongenerationsimulativeexperimentsofsourcerockshadbeenoneofthemainandkeymeanstoconfirmhowmuchgeneratedgasfromsourcerocksinitsdifferentevolvementphases,andtoascertainthechangingcharacteristicsofitsoutcomes.BymakingexperimentsusinglowermaturedsourcerocksinthefourthsectionofShahejieformationofJiyangdepression,severalruleshadbeenfounded,thosewere:thegenerationrateofgashydrocarbonandliquidstatehydrocarbonhadbeenhoistedwithtemperatureheightened,whenthetemperaturehadbeenexceedover400∀,thegenerationrateofliquidstatehydrocarbonhadbeenputtingoutdepressingtrend,butthoseofgashydrocarbonalsobeenincreasing;moreover,suchimitatingsolidoutcomesasTOC,H/C,S1+S2,HIhaddecreasedwiththetemperatureincreased.Theseruleswillhelpustodeeplyunderstandtheevolvementprocessofsourcerocks,andhavedramaticgeologicalmeaningsincalculationthequantityofoilandgasresourcesinthefourthsectionofShahejieformation.KeyWords:Jiyangdepression,SourcerocksinthefourthsectionofShahejieformation,Simulativeexperiment,Simulativehydrocarbongenerationratio.StructuralFeaturesandClassificationoftheGentleSlopeZoneinJiyangDepressionZhangYu(ManagementDepartmentofExplorationProject,ShengliOilfieldCo.Ltd.,SINOPEC,Dongying257000,China).FaultBlockOil&GasField,2005,12(3):2224ThestructuralpatterntothethegentleslopebeltofJiyangdepressionisclassified,andputforwardsthecombinationcharacterofthedevelopmentextentofthebasementriftandthelaststageactivityandtheearlytertiaryfaultwithsedimentastheclassificationcriterion.Thisisthefirsttimethatthegentleslopeisclassifiedintotwobigcategoriesaccordingtothegenetictexture:singleriftanddoubleriftgentleslope,whichitisalsoclassifiedintofourtypesindetai:lslopebreak,piecewiserift,horstgrabenandhalfgraben.Summarizedfourdifferentoilandgasreservoirmigrationandconcentrationformationmodelscombiningthegeologicalenvironmentformingeverykindofthegentleslopeandthecontrollingfunctiontooilandgasreservoirformation.KeyWords:Jiyangdepression,Gentleslopebelt,Genetictextureclassification,Reservoirformationmode.lIdentifyandStudyonSeismiteinCoreAnMingquan(GeologicalScientificResearchInstitute,ShengliOilfieldCo.Ltd.,SINOPEC,Dongying257015,China).FaultBlockOil&GasField,2005,12(3):2527Inmanagingandstudyingthecore,wehavefoundseismiteincoreofEs3andEs4inDongyingsag.Thepaperintroducestheseismite'srecognitionmarks,establishestheseismicsequencesystemandanalysesthesinglewellsequencesystembasedontheprocessofseism.ItisconsideredthatthemovementofearthquakewasviolentandfargoingonthetimeofEs3andEs4inDongyingsag.KeyWords:Seismite,Core,Recognitionmark,Seismicsequencesystem.StudyonDimensionalDistributionofFlowUnitsinMeanderingSandstoneReservoirTalkingaboutGuantaoFormationinChengdaoOilfieldasAnExampleLiuWei(ManagementDepartmentofExplorationProject,ShengliOilfieldCo.Ltd.,SINOPEC,Dongying257000,China).FaultBlockOil&GasField,2005,12(3):2831Itisthefirsttimethatthepartitionmethodofflowunitsab
