Abstract:
It was estimated that the prospect perspective were weakness in Zhidan area once,since data was narrow,and prospect is difficult for complicated landforms (vale,ridge and replat).In this paper,by explored geo-physico-chemical prospecting method for looking for oil in prior prospect,the authors summ arize a suit of prospective technique and program,which is valid to oil-geology trait of Zhidan area and composed of: oil-gas geo-chemical prospect (acid degradation of hydrocarbon,absorbed-fluorescent spectrum,ultraviolet radiation spectrum,methane carbon-isotope)→non-seismic detection in favorable explorative area which confirmed by chemical prospect (matural potential,gamma energy spectrum,accurately magnetic analysis)→resistively prospecting in anom alous area which confirmed by physical-prospect→successful general evaluation of geo-physicochemical-prospect.Compared with routine petroleum exploitation,non-seismic physic-chemical prospect combined with geologic research show many obvious characters such as low-cost,short-period and high success rate,ect,especially to looking for non-struct ural oil-gas pool.
