摘要
为了评价莺歌海盆地中深层储层质量,并预测有利储层发育区,本文在成岩作用研究的基础上,利用成岩作用数值模拟方法遵循“点—线—面”的原则,对全盆地成岩场从单井到剖面再到平面进行了深入和广泛的研究。在恢复LT1-1-1A埋藏史的基础上,进一步讨论了其有机质和成岩演化史的的关系。研究结果表明,在同一深度下,由于超压对成岩作用的抑制和地层时代的影响,从中央底辟区到莺东斜坡带成岩作用强度依次增强,并且有机质热演化速率与成岩演化速率并不完全同步;梅山组地层成岩平面展布规律表明,一号断裂以东由于埋藏较浅,储层物性较好,以原生孔隙为主,但有机质一般未成熟,成岩较弱,处于早成岩阶段A期—B期,主要发育早期压实相和胶结相,较难形成油气聚集。而一号断裂以西至中央底辟区以东,不但温度压力适中,烃源岩大量生烃,并且干酪根生成有机酸也达到高峰,溶蚀邻近储层,形成大量次生孔隙,为油气注入创造了条件,成岩阶段属于中成岩阶阶段A1亚期-成岩阶段A2亚期,生、储、盖层发育俱佳,是油气大规模聚集成藏的关键时期。而在中央底辟带东方区的西部和乐东区的中南部,由于埋藏较深,成岩较强,进入中成岩阶段B期,有机质处于过熟阶段,储层质量较差,难以成藏。
     沉积相和成岩作用共同决定储层现在的状态,在综合考虑这两个因素的基础上,根据逐步回归原理,建立了不同沉积微相平面的孔隙度预测模型,对莺歌海组储层孔隙度进行了预测。在平均填隙物含量高达29%的条件下,孔隙度预测平均误差2.48%。在对莺歌海盆地全区现已发现的含气储层物性进行数学统计分析的基础上,制定了适用于全区储层的物性下限,并预测了黄流组二段地层有效含气储层的分布范围。
     通过对莺歌海盆地全区成岩作用数值模拟和储层质量预测,其研究成果不但补充和完善了成岩作用这一学科的理论,并且改变了国内在该地区储层研究和认识较少的现状,更为寻找有利储层发育区指明了方向,其理论成果对指导油气勘探具有重大意义。
The article researchs into the diagenesis field of the YingGeHai Basin deeply and widely from single well to profile and then to plane,making use of Diagenesis numerical modeling according to the method of "dot—line—plane",in order to assessing the reservoir quality of the Middle-Deep Strata of YingGeHai Basin and predicting the developed range of profitable reservoir. In the base of inverting burial history, the text further disgusesses the relation between thermal evolution of organic matte and diagenic evolution; The finding shows that, because of the overpressure retardation of diagenesis and effect of the long diagenic time, the diagenic intensity heightens of "3485 profile" ordinally from the centre diaper region to yingdong slope zone and they don't evolve synchronical in the same depth. The plane throughgoing rule of diagenic field in the formation of meishan group demonstrates that, it has an better reservoir quality and the primary pore developed well,but oridinarily, the organic matter keeps the phase of prematurity and the situation of weak diagenic intensity, and the correspondent layer is in the stage of early diagenesis A-B phase and develops the facies of early compaction or cementation in the east of No.1 fault, which is the reson why the region is difficult to formatting oil and gas accumulation. But in the area between the west of No.1 fault and the east of centre diaper region, where the tempruture and pressure is fitable, the mother rock that is rich in organic matter generated a large amount of hydrocarbons, and the organic acid of kerogen generating was up to peak, so that these organic acids went into adjacent reservoir to format a lot of induced porosities which produced a good condition of oil and gas migrating into reservoir. The area is in the stage of middle diagenesis A1~A2 subage, which the condition of generating hydrocarbon, researvoir and capping formation both deveped very well, which was critical phase of formatting oil and gas accumulation. While in the western DongFang zone and middle—southern LeDong zone of the centre diaper region,the diagenic intensity is too powerful and belongs to the stage of middle—diagenenic B phase in which the organic matter keeps post mature, as it has a deeper depth, its reservoir quality is too poor to accumulating reservoir.
     It is known that the nowadays'condition of reservoir is desided by sedimentary facies and diagenisis. In the base of considing them,the text sets up the single well and plane model of porosity prediction to predict the porosity of the formation of yinggehai group, according to the principle of multiple element linearity stepwise regression. In the condition that the averge content of interstitial matter is 29%, the averge corrigendum of the model is 2.48%.Though analyzing the gas containing reservoir that has found in the YingGeHai Basin and making use of the method of statistics, the lower limit of physical property is formulated so that it is able to fit the whole basin, then predict the distribution range of valid gas containing reservoir in the formation of huangliu group.
     By means of diagenesis numerical modeling and reservoir quality prediction in YingGeHai basin, the studied fruit of the text can not only supplement and prove the course theory of diagenesis but also can change present situation that the research and knowledge of reservoir in the basin is less,further the method and outcome have an very important affect on finding the deveped region of beneficial reservoir and guiding the oil and gas prospecing.
