Isobaric identification with gf - tof method is based on the different time of flight caused by the different energy loss. the resolution of gf - tof is mainly affected by two factors. first, the rises time of current pulse from start and stop detector
Gf - tof方法對同量異位素的分辨取決于e的不同而產生的時間不同,時間分辨僅來源於定時探測器電流脈沖上升時間的快慢和離子在氣體介質中的能量離散。Stoneley wave is a kind of guide waves propagating along the liquid - solid interface in well. when a sonic beam strikes the surface of a thick plate immersed in a liquid, a stoneley wave is generated. stoneley wave approach is applied on analysis of well logging more and more widely in recent ten years with the introduction of advanced analysis methods for component waves from full - waveform array acoustic log data. the spectrum of stoneley waves are used to identify the fractured zones and quantitatively calculate the fracture parameters of reservoirs, especially to evaluate the validity of fractures at fracture - type complex reservoir
斯通利波是一種沿井壁傳播的聲波,當聲波脈沖與井壁和井內流體的界面相遇時就會產生斯通利波。近十幾年來,由於長源距和偶極子陣列聲波儀在測井中的廣泛應用和全波形陣列聲波測井資料中各組分波的處理分析方法的進步,可將斯通利波分離出來單獨研究並應用於測井資料分析。斯通利波技術是評價裂縫及其滲透性的有效方法。When the triggering light goes, the avalanche impact ionization and recombination radiation in the domain result in the formation of the carriers " conductive channel in the body of the devices and control the current of the lock - on switching
