摘要：

桥口构造沙三段气藏具有埋深大、含气井段长、储层物性差且纵横向变化大、气层产能低、压力不稳的特点。通过对岩性成分、结构、沉积相带、物性、盖层、构造、烃源岩演化等多方面控制因素的分析认为,在诸多的控制因素中,沉积相带是主控因素,重力流水道砂体及湖底扇中扇辫状水道不仅物性好,而且埋藏在生烃洼陷泥岩之中,利于捕获油气而富集成藏。因此,加强沉积相的精细研究,将地震资料与测井资料结合起来分析有利的沉积相带,进行储层预测,将是下步勘探工作的重点。

Abstract:

Gas reservoir in Es3 interval of Qiaokou structure is characterized by its great buried depth,long gas-bearing interval,poor physical property,great change longitudinally and transversally,low productivity of gas bearing strata and unstable pressure.It is believed,by analyzing structure of litho-composition,sedimentary facies belts,physical property,overburden,structure and hydrocarbon evolution,that sedimentary facies is the main factor among several controlling factors,gravitational flow channel sandbody and physical property of fan-braided channel in the sublacustrine fan is not good but also buried in mudstone of hydrocarbon genetic depression which is favorable for hydrocarbon trapping and accumulating to reservoir.Therefore,it is necessary to stress the importance of next step exploration by strengthening a carefully study of sedimentary facies,analyzing those favorable sedimentary facies by combining seismic data with data of well-logging,predicating reservoir.

Key words: Qiaokou structure, Es3 interval, characteristic of gas reservoir, sedimentary characteristic, sedimentary facies, controlling factor
