泌阳凹陷安棚油田深层系储层岩石学特征

A Petrology Feature of Deep-buried Information in Anpeng Oilfield Biyang deposition

泌阳凹陷安棚油田深层系特低孔特低渗透油气藏因地质认识程度低 ,油层压裂改造措施针对性不强 ,油田开发经济效益不理想。鉴于此 ,应用普通薄片、铸体薄片的镜下观察资料对储层的岩石学特征进行了认真研究 ,结果发现安棚油田深层系储集岩的成分成熟度和结构成熟度均较低、成岩作用强烈、储层填隙物以碳酸盐为主。储层的这一岩石学特征 ,为下一步的滚动勘探开发提供了关键的技术支持。

Because of the degree of geological understanding is low to the deep-buried pool with super-low porosity and permeability in Anpeng oilfield, Biyang deposition; The fracturing operation to the information is not to the point, and the economical benefit of development is not to the ideal. So, the author carefully studied the petrology feature of reservoir by researching common slice and casting slice under the microscope ,the result indicated that: the reservoir of deep-intervals in Anpeng oilfield is with a low degree of ripe in the ingredient and structure、and a great rock formation effect, and a main carbonate in the pore. Knowing this, offered an important technological support for future trundling exploration and exploitation, and found a point for effective information fracturing and enhancing economical benefit in the exploitation of the oilfield.
