| 摘 要： | 通过取心井的岩心观察和室内分析，结合沉积微相的研究，探讨了临盘油田沙二下亚段成岩作用特点，建立了滩坝沉积的埋藏成岩演化模式．通过研究认为，尽管沙二下亚段埋藏较浅，但成岩作用已达到晚成岩Ａ１期，储层总体上处于弱压实、弱胶结状态，次生孔隙较发育．由于沉积和成岩作用的共同影响，处于原始高位的坝顶砂岩为较好的油气储层．

| Abstract: | On the basis of core observation and laboratory analysis, as well as study on sedimentary microface, the paper deals with diagenesis and its control over reservoir properties of the lower Es 2 in Linpan oilfield.The diagenetic evolutionary pattern of shallowlly buried bar sandstone is set up. The study showed that the reservoir of Es 3 in Linpan oilfield has been weakly compacted because of shallowlly buried and weakly cemented with abundent secondary porosity. The diagenesis of lower Es 2 reached stage A 1 of tedodiagenesis. Sand in top bar microface is good reservoir under the control of sediment and diagenesis. |
