摘要: 琼东南盆地深水区新发现了陵水A-2大气田,钻井揭示其中央峡谷黄流组内充填有多期优质厚层的浊积水道砂岩,且被后期泥质水道切割及块体流改造,各期砂体的叠置关系复杂。为此,利用三维地震、最新钻井岩心、壁心、岩屑化验及测井等资料,综合分析了琼东南盆地中央峡谷充填砂体的成因及其展布规律。结果表明:中央峡谷内黄流组至少发育4套厚层优质储层,且以灰色细砂岩、粉砂岩为主,砂体为浊流沉积。砂体的堆积样式为垂向孤立式和侧向加积复合式。砂体的分布具有分段性,纵向上HL_Ⅰ砂组和HL_Ⅱ砂组在中央峡谷内均有发育,HL_Ⅲ砂组和HL_Ⅳ砂组在中央峡谷中下游段发育;横向上,峡谷平直段-低弯曲段砂体一般连片分布,中-高弯度段砂体呈独立块状分布。另外,根据中央峡谷内砂体在纵向上相互叠置、横向上连片分布的特征,建立了中央峡谷黄流组5期砂体在空间上的立体展布模式,对预测类似砂体分布具有重要意义。

Abstract: Lingshui A-2 gas field was discovered in deepwater area of Qiongdongnan Basin. Well drilling reveals that multi-period high quality thick layer of turbidity channel sandstone developed in Huangliu Formation in Central Canyon. The filled channel standstone was cut by the late muddy channel and reformed by MTDs. The stacked relationship of multi-period sandbodies is very complex. So,the genesis and distribution regularity of the Central Crayon filling sandbody in Qiongdongnan Basin were studied using 3 Dseismic and the latest drilling data. The results show that the Central Canyon at least developed four sets of thick and high-quality reservoirs which are sand of turbidite deposits and the lithologies are primarily grey fine sandstone and siltstone. The accumulation styles of sandbody are vertical isolation and lateral accretion,and it is segmented in the distribution of sandbody. Vertically,Ⅰ and Ⅱ sand groups developed throughout the entire canyon,but Ⅲ and Ⅳ sand groups only developed in the middle and lower of the canyon. Horizontally,sandbodies developed contiguously in the straight-low bending section of the canyon and were independent block developed in the medium-high bending section. In addition,it is of important significance for exploration to establish a pattern which is longitudinal overlap and horizontal continuous distribution of sandbody to predict similar sandbody distribution in the Central Canyon.

Key words: reservoir accumulation rules, migration system, Shawan Formation, Junggar Basin
