东濮凹陷滚动勘探开发实践——东濮环洼

The Puwei Wreath Depression to Explore the Exploration and DevelopmentFulfillment

以层序地层学理论为基础,提出应用坡折带理论寻找陆相湖盆斜坡带油气藏的方法。通过东濮凹陷的中央隆起带北部濮卫环洼带滚动勘探开发实例,分析和总结构造坡折带成因机制、特点和构造样式。提出坡折带圈闭条件好,储层发育,是环洼聚油气条件最有利地区;沿着坡折带延伸方向砂体发育程度变差,储量丰度相继降低;高台阶油气充满程度最高。通过"十.五"期间的实践发现并动用了一批储量,取得了较好的滚动勘探开发效果。

On the basis of Sequence Stratigraphy theories, put forward an applied ascent to fold to take theories to look for six mutually the lake basin the slope takes the method that the oil spirit hide. Pass the DongPu depression central swell up to take the northern The Puwei Wreath pression to explore the exploration and development actually some examples, analyze to construct an ascent to fold to take with summary because of mechanism,characteristics and structure style. Put forward the ascent folds to take a turn to shut a condition good, keep the layer growth, is The Wreath depression to gather the most beneficial region in the oil spirit condition;Along the ascent folds to take the extension direction sand body growth degree to become to differ, keeping a plentiful degree of quantity to lower one after another;The high step oil spirit is filled with degree tallest. Pass ＂ten ~ Five＂the the fulfillment detection of the period used also a the batch keep quantity, obtaining to roll over to explore the exploration and development result more and goodly.
