中国海相层序油气地质个性与勘探策略
|
摘要
中国海相地层的油气勘探直至近几年才获得重大突破,原因在于中国的海相油气地质的复杂性。中国古大陆板块的个性造就了中国海相盆地演化的多旋回性,由此形成烃源岩热成熟度高、目的层埋深大、保存条件差等个性。海相油气藏多具有多期次充注—调整改造—再充注的特点,且以气藏为主。中国海相油气勘探的策略应是以有效烃源岩、储集层及保存条件评价为基础,立足于古隆起发育区、海陆过渡相生储盖发育区、有效烃源岩与大面积储层的叠合区勘探,加强基础地质、地震、测井等综合研究,以提高勘探目标的预测性。
Owing to the complicated situations of the marine petroleum geology in China,it is until recent years that some exploring breakthroughs had been taken in marine sequences.The characteristics of China's paleo-continent plates brought up the multicycles of marine basin evolutions,which consequently resulted in high maturity,deep-buried target beds and poor preservation of marine source rocks.Marine hydrocarbon reservoirs usually went through two or three times of filling-adjusting-replenishing stages. Most of them are gas-bearing reservoirs.It is suggested that exploration tactics of Chinese marine sequences should be based on assessment of effective source rocks, reservoir rocks, and preservation conditions,and should put exploration aims at the regions where there are developed paleo-uplifts,marine-continental transitional facies of source-reservoir-cap assemblages and large-scale reservoirs overlapping on effective source rocks. It is important to strengthen the synthetic research on geology, seismology, well-logging, so as to improve the percentage of prediction for exploration targets.
