陆相储层流动单元的研究方法

针对陆相辫状河三角洲纵横向相变化快的特点，通过对吐哈盆地温米油田三间房组油藏的研究，提出了一套陆相储层流动单元的研究思路和方法：①确定连通砂体与渗流隔挡的分布；②确定连通砂体内部导致渗流差异的储层质量差异，对该区目的层段储层进行分类评价。根据综合评判方法，将储层分为四类。通过油田注水开发效果检验，证实了该分类结果具有科学性、准确性和预测性，对开发温米油田起到了指导作用。

STUDY METHODS FOR FLOW UNITS IN CONTINENTAL RESERVOIR

Aiming at vertical and lateral variation of braided stream delta in nonmarine reservoirs, a new set of research technology for reservoir now units is suggested according to the study of reservoirs in Sanjianfang group of Middle Jurassic in Wenjisang-Mideng oilfield. The research of reservoir flow units includes two steps. The first step is to determine some connecting sandbodies and flow barriers, and the second one is to analyze the quality differences of reservoir in the same connecting sandbodies which leading to different flowing pattens. The target strata in the studied region are evaluated with synthetic judgement method. The. reservoirs in this area are classified into four groups. The effect of waterflooding development of Wen-Mi oilfield proves that the classification is reasonable and beneficial to development of Wen-Mi oilfield.
