摘要:

近年来莺歌海盆地东方区中深层勘探获得重大突破,取得了一系列认识,但由于地质条件复杂,目前对于同为莺歌海盆地的乐东区中深层高温超压气田的成藏认识并不清楚。在微观地球化学信息剖析基础上,结合地质、构造研究成果,对比分析盆地东方区和乐东区中深层天然气成藏特征。研究表明,东方区与乐东区天然气成藏既有明显差异性也有相似性,差异主要表现为:东方区生烃早、持续时间长,而乐东区生烃晚、晚期快速生烃;东方区烃类气开始充注成藏的时间约为3.0Ma,而乐东区烃类气的成藏约在1.7Ma之后,即与东方区相比乐东区成藏较晚,因而储层物性对大规模成藏制约作用更加显著。东方区和乐东区天然气成藏时限均受控于生烃过程与底辟活动时间,同时天然气分布与底辟活动能量密切相关。正因二者成藏有同有异,乐东区勘探可以借鉴东方区成功经验,但不能复制东方区成藏模式,综合研究认为在能量较低的底辟波及区进一步寻找物性好的储层,是乐东区下一步优质天然气勘探的重点。

Abstract:

Recently great breakthrough in natural gas exploration has been obtained in mid-deep strata of the Yinggehai Basin,but the accumulation characteristics of the natural gas in mid-deep strata,especially in Ledong area is still indistinct because of the complicated geologic conditions.In this article,macroscopical geological analysis and microcosmic geochemical detecting techniques are used to research the gas accumulation difference in mid-deep intervals between Dongfang and Ledong areas.It is concluded that,compared with Dongfang area,extensive gas generation of the source rocks in Ledong area is relatively late but much faster,hydrocarbon gas began to accumulate at about 3.0Ma in Dongfang area while 1.7Ma in Ledong area.At the same time,there are some common ground in Dongfang and Ledong areas such as the hydrocarbon generation process and diapir activity controlling the gas accumulation,and the natural gas distribution is closely related to the diapiric activity energy.So,mid-deep intervals in diapir circumjacent areas with good physical properties will be priority exploration areas in Ledong area.
