| titleOfInvention | Oil and gas development adopts sand control and water control device |
| abstract | The invention discloses a sand and water control device for oil and gas opening, which comprises a valve body arranged in a screen pipe or at the connection of the screen pipe; block; the baffle is under the weight of the counterweight so that the baffle is below the screen. In the present invention, when the screen tube is rotated into the horizontal well to stabilize the screen tube, the baffle plate is always at the bottom under the weight of the counterweight block, the filter net can filter the soil when oil is exploited, and when the oil is further exploited by water injection, multiple heights Different baffles can allow oil to enter the last screen baffle when water is injected. The baffle can block the entry of water and only extract the oil on the water surface. For further exploitation, the concentration of oil exploitation is greatly improved, which is suitable for popularization and use. |
