By analyzing reserve forming conditions of high evolution marine strata , including types of hydrocarbon source , the structural evolution , the condition of preservation and so on , it is considered that under the background of intensive structural movements , the " second " compensatory capabilities of the hydrocarbon source in the middle and lower yangtze region and regional preservation conditions would be the major factors to control the enriched oil and gas collection in this region 從分析高演化海相地層的烴源類型、構(gòu)造演化以及整體封存等成藏條件,認(rèn)為中、下?lián)P子地區(qū)在強(qiáng)烈的構(gòu)造運(yùn)動背景下,烴源巖的“再次”補(bǔ)給能力和區(qū)域保存條件將成為控制中、下?lián)P子地區(qū)油氣富集的主要因素。
