负向构造

濮卫环洼带是东濮凹陷中央隆起带北部的一个次级负向构造单元。

The oil-bearing belt around Pu-Wei sag is a sub-ordinary negative structure unit in the northern part of Dongpu depression .

共包括六个负向构造单元（东北凹、北凹、中凹、西凹、南凹、东凹）和三个正向构造单元（北凸、西凸、南凸）。

It included six minus structural units ( Northeast concave , north concave , middle concave , west concave , south concave , east concave ) and three plus structural units ( north protruding , west protruding , south protruding ) .

Ⅲ级分为正向、负向火山构造；

The ⅲ grade be the positive , negative volcanic structure ;

并对微型构造类型进行了研究，主要微型构造类型为正向微构造、负向微构造和斜面微构造。

On the study of structural type , positive microscopic structural , negative microscopic and oblique microscopic structural are taken as the main microscopic structural types .

在确定加密井井别时，应尽可能地把生产井钻在正向微构造区，把注水井钻在负向微构造区。

In the designing of well locations , according to mini-structure , infill wells should be drilled on the positive mini-structure areas and only injection wells are drilled in the negative mini-structure areas .

现行的构造单位划分方案中，东濮凹陷属于临清坳陷，是位于渤海湾盆地最南端的一个负向三级构造单位。

In present structural unit classification scheme , Dongpu Depression belongs to Linqing Sag as a third class negative element in the southmost of Bohai Gulf Basin .
