摘　　要：黄龙场气藏属碳酸盐岩岩性圈闭气藏。黄龙场构造在长兴期地跨海槽、陆棚边缘及深缓坡3个相带,生物礁主要发育于开江—梁平海槽东侧的陆棚边缘相内,以北东向呈串珠状分布。礁储层纵向上主要发育于长二—长三段,属面积、礁组合厚度较大的边缘礁体,岩性以白云岩为主,礁储层非均质性强,不仅表现为横向分布上的非均质性,而且还表现为纵向上储层特性的非均质性,储集类型为裂缝—孔隙型。近年来,黄龙场生物礁储层预测取得了一定的进展,预测成果展示出了本区生物礁发育规律。Huanglongchang gas reservoir is a carbonate rock lithologic trap reservoir. Moreover, three facies belts of trough, shelf margin and deep ramp were developed at the Huanglongchang Structure in Changxingian. Bioreef,with a NE trending and scattered as moniliform,mainly develops at the shelf margin facies of the east Kaijiang-Liangping Trough. Longitudinally, bioreef reservoirs, dominantly developed at Changxing 2 to Changxing 3 members, are a kind of marginal reef bodies with larger area and thickness. They mainly consist of dolomite and characterized by strong heterogeneity(also including laterally)。 And the reservoir type is fractured-porous one. Recently, the Huanglongchang bioreef reservoirs have been predicted and obtain some achievement. And the predicted results may also show their development law.
