oil-producing formation的意思|示意

Active water or light oil is sent downhole through hollow rod to reduce oil flow resistance, thus producing heavy oil from deep formation through screw pump.

利用空心杆向井筒内掺入活性水或稀油，降低油流阻力，实现应用螺杆泵开采深层稠油。

Darcy's law indicates that formation pressure of an oil well has some correlativity with wellbore fluid producing volume and bottom hole flowing pressure.

达西定律表明，油井地层压力与井筒产液量和井底流压具有相关性。

The tool also can be used for evaluation of formation oil saturation and formation flooding degree perfectly in an old producing well.

在已投入生产的老油井中，能够较好地评价储层的剩余油饱和度及水淹程度；

Boundary response, fast drop of reservoir pressure and rapid increase of producing gas oil ratio all show limited oil in place of the formation, which behaves like lenticular reservoir.

边界反映、地层压力快速下降及生产气油比迅速增大都说明该层储量有限，表现出透镜状油藏的特征。

In addition, the techniques of producing remaining oil, preventing formation damage, improving drilling and completion and deep well production should be studied.

另外，挖潜剩余油技术、解除油层伤害技术、提高钻完井技术、深井采油技术等也需要攻关。

A well drilled down the flanks of structure or on the outer limits of a producing formation. An edge well often penetrates the oil-water contact.

沿构造翼部下倾部位或在产层外边界上所钻的井。边缘井经常穿透油水界面。
