摘要:
采用可控脈沖中子源(脈沖中子發生器)代替傳統化學源,實現了測井過程零放射性污染; 采用多組超熱中子及熱中子探測器。結合巖性校正、儀器與井壁間隙校正、套后井套管水泥環校正以及放射源強度校正等孔隙度校正算法,實現套前、套后模式高精度測井。從陣列中子孔隙度測井儀現場試驗井中選取了1口有代表性的測井資料,通過分析重復性、一致性和縱向分辨率證實陣列中子孔隙度測井曲線能準確地反映地層孔隙度。
Abstract:
The controllable pulsed neutron source(pulse neutron generator)instead of traditional chemical source was used in this tool, which realized zero radioactive pollution during logging. Moreover, many sets of ultra-thermal neutrons and thermal neutron detectors were also used in this tool. Combining the porosity correction algorithms such as lithology correction, clearance correction between tool and well wall, casing and cement correction of cased well, and radiation source strength correction, the high precision logging for open hole well and cased well was realized. Logging data of a representative well from the wells which using array neutron porosity logging tool was selected for testing, and it was found that the repeatability, consistency and longitudinal resolution of the data was great, which mean the array neutron porosity logging curve can accurately reflect the porosity information of formation.
