GENESIS OF THE DOLOMITE IN THE SHAHEJIE FORMATION OF JZ OILFIELD, BOHAI BASIN

    摘要

  • 研究区以生屑白云岩及含砂屑的鲕粒白云岩为主，相邻井区白云岩类型及厚度变化大。为确定各类白云岩的成因，通过孢粉及微体古生物化石、碳氧同位素、微量元素B含量等分析手段，对本区的古气候、古环境、古沉积介质的物理化学性质进行系统地分析，自沙三段以来，由温暖的亚热带气候变得逐渐干燥，水体逐渐咸化，为白云岩的形成提供了必要条件。具有硬的基底的滨浅湖台地，水体能长期保持清澈，有利于底栖生物生长繁殖，适宜碳酸盐岩的形成、沉积了巨厚的生屑白云岩，其生屑含量高、孔隙较发育、方解石也被交代的更加彻底，建立了该类白云岩滨浅湖台地渗透回流成因模式。滨浅湖隆起带区域，淡水与咸水在此交汇，易形成具雾心亮边的粉晶白云岩和具有同心圆结构的鲕粒云岩或生物碎屑云岩，但常常白云石化不彻底，方解石含量高，个别井段甚至发育云质鲕粒灰岩，建立了该类白云岩滨浅湖隆起带混合水成因模式。此研究丰富了湖相白云岩成因模式，对渤海湾盆地碳酸盐岩的勘探具有重要的指导意义。

    Bioclastic dolomite and sand-bearing oolitic dolomite are widely distributed in the study area. Drilling shows that the lithology and thickness of dolomite vary greatly from well to well. In order to reveal the genesis of the dolomite, the physical and chemical properties of the depositional media, paleoclimate and paleoenvironment of the area are systematically studied by means of sporopollen and micro paleontology, carbon and oxygen isotopes and trace element B. It is found that since the 3rd Member of the Shahejie Formation, warm subtropical climate had gradually turned to dry, and the water body become salty, which provided basic conditions for the dolomite to form. On the nearshore and shallow lake platform with hard basement, however, water was clean, which was in favor of the growth and reproduction of benthic organisms and the formation of limestone and bioclastic dolomite with huge thickness. As the bioclastic content is high, pores are well developed, and the calcite is also more thoroughly replaced by dolomite. Upon the basis, a seepage reflux model for such kind of dolomite platform is established by the authors. In the uplifting zone of the nearshore and shallow parts of the lake, where fresh and saline water mixed, it is easy to form the silty dolomite with sparry edge and cloudy nucleus and the oolitic dolomite or bioclastic dolomite with concentric structure. However, dolomitization is often incomplete, calcite content is high sometimes, and therefore dolomitic oolitic limestone is common in some wells. For these dolomitic deposits, a genetic model of mixed water is proposed specially for nearshore-shallow lake uplift zones. The genetic models of lacustrine dolomite are of important significance for hydrocarbon exploration in carbonate rocks in Bohai Bay Basin.
