Fractal Identification Of The Reservoir Lithofacies

Lithofacies　is　one　of　the　key　reservoir　parameters　in　oil　fields,　which　has　been　given　most　attention　and　effort　by　petroleum　engineers　and　well　logging　experts　as　the　important　question　for　discussion　both　in　board　and　overseas.　And　the　sandstone　lithofacies　is　the　primary　type　of　hydrocarbon　reservoirs　now.　So　it　is　the　completely　necessary　and　very　significative　task　to　identify　the　reservoir　lithofacies.　　The　thesis　includes　four　parts　basically,　and　one　model　was　established　to　forecast　the　reservoir　lithofacies　for　studying　the　reservoir　lithofacies:　In　the　first　part,　it　was　introduced　to　the　basic　principle　of　fractal　geometry,　among　which　includes　the　background　and　the　present　situation　of　the　fractal　geometry　theory　and　among　which　includes　the　mathematics　foundation　of　the　fractal　geometry　and　among　which　includes　the　measurement　method　of　the　fractal　dimension,　which　has　established　the　solid　foundation　for　the　back　inquirement.　In　the　secong　part,　it　was　introduced　to　the　XingLong　Tai　oil　reservoir　characteristic　of　the　Qian　Twelve　Block,　among　which　includes　the　deposit　condition　analysis　and　lithofacies　characteristic　and　rock　characteristic　and　matter　of　 reservoir　and　pore　structure　characteristic　of　reservoir,　among　which　lithofacies　is　especially　important,　which　has　established　the　foundation　for　the　identification　of　lithofacies　of　reservoir　in　the　next　chapter.　In　the　third　part,　it　was　introduced　to　the　fractal　characteristic　of　reservoir　rock　and　the　calculation　of　the　fractal　dimension,　among　which　includes　the　pore　structure　of　rock,　　among　which　includes　the　fractal　characteristic　of　the　　structure　of　the　formation　and　rock　,among　which　includes　the　fractal　characteristic　and　computational　method.　Calculate　the　fractal　dimension　of　four　core　wells　at　the　different　depth,　which　has　established　the　foundation　for　the　next　effictiveness　analyses.　　In　the　four　part,　it　was　introduced　to　the　computional　method　of　the　fractal　dimension　and　the　reality　handle　of　the　well　logging　curves,　among　which　includes　the　computational　method　of　the　fractal　and　resemblance　research　of　the　well　logging　curves,　among　which　includes　pretreatment　of　the　well　logging　curves,　among　which　includes　the　fractal　dimension　computional　method　and　result　and　influence　factor,　among　which　includes　forecasting　the　　unkown　lithofacies　utilization　of　the　GuanLianwei　method　of　the　well　logging　curves.　This　part　is　the　point　of　article　,and　also　is　the　course　of　identifying　lithofacies　to　make　use　of　the　fractal　theory,　which　was　introduced　to　a　completely　new　method.　And　I　forecasted　the　reservoir　lithofacies　of　two　mouthfuls　of　wells　using　the　GuanLianwei　method　of　the　well　logging　curves.
