摘要

摘要: 非常规油气勘探开发给录井的探测分辨率、数据质量、录取参数齐全度和评价方法有效性带来了挑战。经过"十二五"攻关研究，研发了元素录井、钻井液核磁共振在线录井、小型化高分辨率三维核磁共振录井和前置式高分辨率气测录井等4项新技术，元素录井的元素采集种类从12种扩充到20种以上，填补了钻井液含油量的探测空白并实现了在线测量，岩样的孔喉尺度探测分辨率提高了10倍并将探测维度从一维拓展到三维，气体组分的探测分辨率从C5提高到C8或C10；建立了水平井综合地质导向、致密砂岩油气层录井综合评价、页岩油气层录井综合评价3套方法。随着非常规油气地质体的复杂性及对降本、增产、增效需求的增强，微观结构探测、碳同位素分析、录井仪器一体化等技术及水平井三维立体导向、裂缝型页岩的地层压力随钻预监测等方法将得到有效发展。

Abstract: Unconventional oil and gas pose new challenges to mud logging,including detection resolution,data quality,the completeness of acquired parameters,the effectiveness of evaluation methods etc.Through the study of the "12th Five-Year Plan Period",four innovative logging technologies,namely element logging,on-line logging of drilling fluid NMR,portable 3D NMR logging with high resolution and front setting gas logging with high resolution were developed,and improved the resolution of detecting the elements from 12 kinds to over 20 kinds in the element logging,which fills the gap of on-line detecting the oil content in drilling fluids.In addition,pore throat resolutions of core has been raised 10 times as high as the past,and the detection dimensions changed from 1D to 3D.At the same time,resolution for gas component was improved from C5 to C8 or C10.Three kinds of comprehensive evaluation methods,including geosteering for horizontal wells,tight sand reservoir evaluation and gas shale evaluation,were established.With the increase of geological complexity and requirements for reducing cost,increasing production and efficiency,there is an incentive for developing technologies including microstructure detection,carbon isotope analysis,integration of logging instruments,3D geosteering in horizontal wells,MWD of pore pressures in fractured shale etc.
