摘　　要：葡萄花油田南部沉积环境复杂，储层物性极差，储量评价参数的优选及开发难度大。通过岩心资料分析葡萄花油田南部扶余油层沉积环境、成岩作用等揭示了储层受沉积环境、黏土矿物、成岩作用及其演化程度的影响，认为研究区沉积水体能量低，储层以粉砂岩为主，主河道砂体是相对优质的储层；强烈的压实作用使岩石变得致密，是扶余油层低孔、特低渗的重要原因；伊利石含量高，其特殊的片状形态容易堵塞孔隙和吼道，降低储层的渗透性。因此，搞清扶余油层特低渗透储层影响因素对于寻找可动用储量具有指导意义。South Putaohua Oilfield is characterized by complicated depositional environment and poor physical properties, so the optimal choice of evaluating parameters for the reserves and oilfield development are rather diffi- cult. With the help of core data, the environment, diagenesis and so forth disclose the the influences of the depositional environment, clay minerals, diagenesis and its evolved degree on the reservoirs. The energy of the sediment- ated water is considered rather low,the reservoirs are mainly composed of sihstone and the principal river channel sandbodies is relatively high-quality reservoirs; the strong compaction makes the rocks tight and becomes the im- portant reason for the formation of low-porosity and low-permeability Fuyu oil reservoirs ; high-content illite and its special flaky shape are prone to plug the pores and throats, thus the permeability of the reservoirs are obviously re- duced. Therefore to make sure of the influencing factors on the extra low-permeability reservoirs of the above oil reservoirs possesses a certain guiding significance for the search of movable reserves.
