自喷井

Key techniques for well testing with electric submersible pump on floating drilling vessel have been studied and developed to solve the conventional testing problem that the flowing production test can not conducted by using natural energy because of lack of feed flow or high back pressure of hydrostatic column to formation due to well style.

针对地层供液不足或因为井型使得静液柱对地层的回压过高而不能利用天然能量进行自喷求产从而导致在浮式钻井装置上无法进行评价井常规测试的难题，研发了浮式钻井装置电潜泵测试关键技术并成功应用。

Robert Gates described America's defence spending over the past decade as a gusher, and one that had to be turned off.

罗伯特。盖茨说，过去十年美国的国防支出就像一个自喷井，必须及时将其关闭。

In view of inhomogeneous distribution of fluid pressure, fault-valve behavior and the coupled equations of the current density and fluid flow within the Earth's crust, especially, the observed anomalies in electrical field showed a similar pattern of rapid starting and slow decay, some of these anomalies associated with episodical spouting from borehole or the increase of fluid pressure in wells, it is reasonable to consider that the source of precursory electrical field anomalies is the streaming potential mechanism.

鉴於地下流体压力分佈不均匀、断层阀作用及地下电流密度与流体流的耦合方程，特别是由於电场异常显示出快急始慢衰减的特殊图型，电场异常有的与废油井间歇自喷有关，有的与流体压力增高有关，故认为过滤电势作为电场前兆机制是合理的。

Testing tech with pump can provide a direct basis for knowing reservoir property (formation effective permeability) of nonflowing well dynamically, well's completion degree and red situation of formation, adjusting exploitation plan in injection well to conduct next step of treatment (especially for new well in new district).

随泵测试技术为动态了解非自喷井油藏的储层特性，井的完善程度、地层亏空情况，调整注水开发方案进行下一步增产措施提供了直接依据。

The coordinated values of production rate and the bottom pressure of three-branched horizontal well in

对裸眼完井方式下三分支水平井自喷采油时的协调产量和协调压力实例模拟计算结果表明，该模型适用于求解应用前

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.

供试的6种杂草对该混剂的敏感性存在显著差异：红心藜Chenopodium album、龙葵Solanum nigrum和反枝苋Amaranthus retroflexus对该混剂最敏感，ED90值分别为47.65、71.67和29.17g/hm2；春蓼Polygonum persicaria和苘麻Abutilon theophrasti敏感，ED90值分别为96.91、114.20g/hm2；而番茄不敏感。
