均质性

Therefore,tapping potencial of remaining oil to improving oil recovery,the recognition of reservoir intraformational heterogeneity in channel sandbodies is proposed and the main targets of reservoir IOR in channel sandbodies of mature oilfields are pointed out as follows:①shutting off strongly-waterflooded intervals to control ineffective circulation of injected water;②strengthening water washing in medium-waterflooded intervals in order to achieve the aimed waterflood efficiency and even to exceed it;③enhancing injection-production consistency and injector-producer ratio of non-waterflooded or weakly-waterflooded intervals for the propose of realizing effective displacement and imporving conforma nce.

根据我国东部主力油田储层绝大多数都属于河道砂体，注水开发进入高含水阶段后，层内剩余油超过层间剩余油，层内矛盾上升为主要矛盾这一特点，从挖掘层内剩余油潜力出发，提出要重新认识河流砂体储层层内非均质性，并指出高含水期河流砂体储层改善采油目标主要有：①封堵强水洗段，控制注入水无效循环；②加大中水洗段注水冲洗强度，达到目标水驱效率，并有可能超过目标效率；③提高未、弱水洗段的注采对应程度和注采井数比，达到有效驱替，提高波及程度。

In this paper, the characteristics of reservoir of reservoir of delta frontal sub-faces of PI Formation in the south of Xingshugang are studied with the data of dense well pattern and rock-mineral identification. The delta frontal sub-faces can be divided into lobate delta frontal sub-faces, branched delta frontal sub- faces and sheeted delta frontal sub-faces. The genetic types of sand bodies in different sedimentary envivonments are analyzed in detail, and the distribution and space-matching relationship of different sand bodies are studied. The micro-pore structure type is studied on the base of the thin section analysis, so the reservoir heterogeneity is studied including plane heterogeneity, interlayer heterogeneity, in-layer heterogeneity and microcosmic characteristic.
