探讨济阳拗陷临南—钱官屯地区化探异常成因机制。通过对临南—钱官屯地区不同构造单元油井和干井中酸解烃特征和微渗漏方式的研究,结合石油地质条件,从油气成藏的角度分析烃类运移、聚集及其微渗漏散失的全过程。结果表明研究区北部地层中以扩散为主,南部以渗透为主或者不存在微渗漏效应,揭示渗漏源和盖层条件是烃类微渗漏的主控因素。临南—钱官屯地区近地表化探异常模式为“渗漏源影响下的断控异常模式”,钱斜14井以北盖层条件和渗漏源条件都最优越,是研究区内最有利的勘探区。
探討濟暘拗陷臨南—錢官屯地區化探異常成因機製。通過對臨南—錢官屯地區不同構造單元油井和榦井中痠解烴特徵和微滲漏方式的研究,結閤石油地質條件,從油氣成藏的角度分析烴類運移、聚集及其微滲漏散失的全過程。結果錶明研究區北部地層中以擴散為主,南部以滲透為主或者不存在微滲漏效應,揭示滲漏源和蓋層條件是烴類微滲漏的主控因素。臨南—錢官屯地區近地錶化探異常模式為“滲漏源影響下的斷控異常模式”,錢斜14井以北蓋層條件和滲漏源條件都最優越,是研究區內最有利的勘探區。

This paper studies the genetic mechanism of the hydrocarbon geochemical exploration anomaly in the Linnan-Qianguantun area,Jiyang depression,Shandong,China.From the perspective of hydrocarbon formation, the paper analyses the whole process of hydrocarbon migration, accumulation, and micro-leakage by studying the acidolysis hydrocarbon characteristics and hydrocarbon micro-leakage in oil wells and dry wells in different structural units in the Linnan-Qianguantun area.The result shows that the micro-leakage is dominated by diffusive effect in the northern strata and the penetration or non-micro-leakage in the southern strata in this study area,and the main control factors of the hydrocarbon micro-leakage are the leakage source and the cap rock conditions.In the Linnan-Qianguantun area,the abnormal pattern of the hydrocarbon geochemical exploration near the surface is “fault-controlled abnormal pattern with the affection of the leakage <br> source”.In the area to the north of Well Qianxie 14,the cap rock condition and the seepage source condition are the most promising conditions.So,this area is the most favorable exploration target in the study area.
