The Influence Of Analcime On Conductivity Of Rock Based On Logging Data Interpretation In Haita Area

Analcime is a zeolite group mineral. In recent years, this kind of new mineral resources have been paid more attention. Unique crystal structure makes analcime has important properties with the capacity of cation exchange. Because analcime has such capacity of cation exchange, it has additional electrical conductivity. But, information of conducting research on the mechanism of Analcime ir reported a less. The interstitial material of pyroclastic rock reservoir mainly contains clay, silt level vitroclastic and analcime in most blocks of Haita basin. However, the composition and condition of vitroclastic are various, and the structure of porosity become very complex. No clear knowledge about the conductive mechanism leads to an unclear understanding of water distribution, difficulty of logging interpretation. In response to these challenges, this paper launches the influence research of analcime on rock conductivity based on logging data interpretation in Haita basin.By electrochemical experiments,this paper explores the capacity of cation exchange of vitroclastic particles containing potassium (sodium) ions,, makes conductive mechanism of Analcime clearly through geological simulation, determines the effect of analcime content on the logging data. By studying the characteristics of corresponding logging curves of Analcime in Haita basin, this paper establishes a calculating method of analcime content and evaluation methods of additional electrical conductivity based on the logging data. These results help us to solve the problems existing in the production process directly.When evaluating the results obtained, this paper suggests that the results are more in line with the conlusions of oil test with taking account the impace of Analcime’s cation exchange capacity, and verifies the feasibility of methed that Analcime’ electrical conductivty impact on rock. The method has some practical applications.
