新港地区白云岩储层预测与成藏条件研究

新港地区主要发育砂岩和白云岩 2 种类型的储层，目前针对砂岩储层的研究广泛且深入，而针对白云岩储层特征及展布规律的研究较少，从而制约了该地区白云岩储层的油气勘探。 利用岩心、测井及地震等资料，基于构造、沉积、烃源岩评价及单井储层等分析，结合数据体融合技术，对新港地区白云岩储层的展布规律进行了预测，并对该储层油气成藏的条件进行了研究，从而明确了该储层的勘探潜力。 结果表明：新港地区沙三段储层发育优质烃源岩，为源储一体的原生油气藏，而且分布面积较大，其中沙三₅亚段白云岩储层发育大量裂缝和溶孔，为油气富集提供了有利场所。 该研究对于同类型白云岩储层的研究具有一定的借鉴意义。

Prediction and accumulation conditions of dolomite reservoir in Xingang area

Clastic rocks and dolomite are the main two reservoir types in Xingang area. The previous deep and wide exploration research is only for clastic reservoir. Research on dolomite reservoir characteristics and distribution is seldom, which restricts the dolomite reservoir exploration in this area. Through core analysis, logging and seismic data, based on the analysis of structure, deposition, source rock evaluation and single well reservoir, combined with data volume fusion technology, this paper carried out the prediction of dolomite reservoir distribution, and studied the oil and gas accumulation conditions of Es3, and then made clear the dolomite reservoir exploration potential of Es3 in Xingang area. The result shows that high-quality hydrocarbon source rocks developed in Es3 in Xingang area, oil and gas reservoir type belongs to primary self storage, and the distribution area is large. A lot of fractures and dissolved pores are developed in the dolomite reservoir of Es35 , which provides favorable places for oil and gas enrichment. This understanding has certain reference value for the study of the same type of dolomite reservoir.
