摘要:
渤中19-6 構造的孔店組砂礫巖系及太古界變質巖系,由于儲層巖性復雜、儲層物性差異大,儲層流體識別及油氣藏類型判別困難,早期產能預測難度大。本文充分挖掘錄井、測井參數在復雜儲層流體評價及產能預測方面的優勢:①應用皮克斯勒圖版、異常倍數、Bar 圖分析法、Flair 流體指數法、含烴豐度指數法及巖石力學參數泊松比及體積壓縮系數交會圖版、測壓流體回歸分析等技術結合進行地層流體性質識別;②利用井流物組分相態分析法、四組合參數法等方法進行油氣藏流體類型判別;③針對低孔滲砂礫巖儲層,依據靜態的測井、錄井、巖心分析等資料構建地層模型,根據動態的電纜地層測試及核磁共振資料獲取油藏參數,據此建立了渤中19-6 構造復雜儲層數值模擬產能預測方法。實踐表明,該組合方法能有效識別復雜儲層內流體相變化特征,識別儲層流體性質;能有效判別油氣藏流體類型;在低孔滲砂礫巖儲層,能較準確地進行產能預測,最終測試結論證實本方法的可靠性。
Abstract:
Kongdian Formation glutenite series and Archean metamorphic rock series in Bozhong 19-6 structure are characterized by complex reservoir lithologies and significant difference of reservoir physical properties, so it is difficult to identify the reservoir fluids, discriminate the oil and gas reservoir type and predict the early productivity. In this paper, the advantages of mud logging and logging parameters in the fluid evaluation and productivity prediction of complex reservoirs were tapped sufficiently. First, the properties of formation fluids were identified by combining Pixler chart, abnormal multiple, Bar diagram analysis method, Flair fluid index method, hydrocarbon abundance index method, rock mechanical parameter crossplot (Poisson’s ratio and volume compressibility coefficient), and piezometric fluid regression analysis comprehensively. Second, the types of fluids in oil and gas reservoirs were discriminated by means of the phase state analysis method of components of fluids in well and the four-combined-parameter method. Third, as for low-porosity and low-permeability glutenite reservoirs, the stratigraphic model was established based on static data (e.g. logging, mud logging and core analysis), the oil reservoir parameters were calculated by using the dynamic data of wireline formation test and nuclear magnetic resonance (NMR), and accordingly the numerical simulation based productivity prediction method suitable for the complex reservoirs in Bozhong 19-6 structure was developed. Practice shows that by virtue of this combined method, the phase change characteristics of fluids in complex reservoirs can be identified effectively, the properties of reservoir fluids can be identified, and the types of fluids in oil and gas reservoirs can be discriminated. And when it is applied to low-porosity and low-permeability glutenite reservoirs, the productivity can be predicted accurately. It is verified from the final test conclusions that this combined method is reliable.
