The paper gathered deep layers well logging materiak record well materiak core and cutting material of 27 wells in the daqing district, recognized the different type of igneous rock according to their log response feature, and made a large number of cross plot, then carefully chose several of them which works better igneous rock lithology recognition. made pattern recognition procedure using computer to recognize lithology, synthetical many logging parameter to identify igneous rock lithology. and then on the basis of recognizing lithology, the paper analyzed the lithofacies recognition law in this district
文中採集了大慶地區27口井的深層測井資料、錄井資料、巖心和巖屑資料，根據火成巖的測井響應特徵識別不同類型的火成巖，並做了大量交會圖，精選了幾種識別火成巖巖性效果較好的交匯圖版，編制計算機識別巖性的模式識別程序，綜合多個測井參數識別火成巖巖性，並在識別巖性的基礎上，進一步分析本地區巖相的識別規律，最後結合試油資料，分析本地區火成巖儲集空間的特點及油氣與火成巖巖性和巖相的關系。 -
According to the constructive principles of these diagrams, the following aspects must be thought carefully : the rock types to be studied must be the same or nearly the same as those that can be discriminated by the diagram ; to avoid mixed or incorrect signals that could be produced, two or more such diagrams shall have to be jointly used ; for special rock types, such as a - type granites or potassic igneous rocks, special discriminative diagrams have to be determined and selected respectively ; the samples to be studied can not be altered ; in general, the diagrams must be used carefully with archean samples ; the petrotectonic assemblage or an expert system are recommended to be used together with the discrimination diagrams
強調指出：所採集的樣品必須新鮮（無蝕變或極弱蝕變） 、非堆晶的巖石；選擇的判別圖解必須與判別的巖石類型相一致，即對花崗巖類要用花崗巖的判別圖解，不能用玄武巖的判別圖解；對特殊類型巖石要選擇專門用於該類型巖石的判別圖解，如堿性花崗巖，鉀質火成巖；要應用多種圖解綜合判斷；不能用單個樣品，而應作多個樣品分析；要注意所選擇判別圖解的特別說明等。 -
