摘要
录井油气显示层解释是录井工作的关键环节,解释中有时会遇到不同录井方法解释结果相互矛盾、录井解释与圈闭成藏评价相互矛盾、录井显示与区域油气显示特点相互矛盾的情况,通过对泌阳凹陷B293井等7口典型井录井油气层解释的分析,总结了解决这些矛盾的一些主要经验:注重区块油气显示特点,发挥各种资料在油气层解释评价中的作用,按照不同录井方法对储集层流体性质的反映特征分析录井资料之间的矛盾,综合录井资料判断储集层物性、含油性,在录井资料解释可信的基础上,寻找圈闭成藏评价的矛盾点。在此基础上,提出了录井油气层解释的基本原则:善于借鉴相邻区块油气层解释方法,通过纵横向对比,发现各种录井资料之间的一致性与矛盾性,进而辩证分析、有所侧重、精细解释。
Oil-gas showing layers interpretation is a key point of mud log- ging.During interpretation,the cases of interpretation results from different mud logging interpretation methods being in contradiction to each other happen frequently,for example,the condition of mud logging interpretation being in contradiction with trap reservoir for- mation evaluation and mud logging showings being in contradiction with areal showing features.Through analyzing mud logging oil-gas layers' interpretation for seven typical wells of well B293 etc.in Miyang sag,the paper summed up the main experiences to settle these contradictions,that is,paying attention to block oil-gas showing features,giving full play of all data in oil-gas layers' inter- pretation and evaluation,analyzing the contradictions among mud logging data according to reflection features of various mud logging methods on reservoir fluid property,integrating mud logging data to judge reservoir physical property and oiliness,finding out the contradictions in trap reservoir formation evaluation on the basis of mud logging data interpretation believable,therefore setting forth the basic principles of mud logging oil-gas layers interpretation,i. e.,being good at using the oil-gas layers' interpretation methods of adjacent blocks,through layer-to-layer correlation for a well and stratigraphic correlation between the multiple wells to find the con- sistencies or inconsistencies of various mud logging data,thus mak- ing dialectical analysis and laying special emphasis on some data to realize fine interpretation.
