Laser drilling perforated casing pipe for sand control for oil wells
Perforated pipes as base pipe are evenly distributed and arranged in drilling holes, with strong practicality and high destructive strength. They are often used as sand control and filtration wells in oil wells.
Drilling screen tube is a type of tube filter, commonly made of metal materials, which screens particles of specific sizes to meet different needs The structure of drilling screen pipes is commonly assembled from wire mesh screens, which can be combined and customized according to actual needs
2、 The role of drilling screen tubes
1. Screening of sediment
Washing and screening sediment are necessary steps in oil exploration and extraction. Drilling screens can effectively screen and separate sediments. It can filter particles of different sizes and separate useful minerals and oil and gas.
2. Sand control for oil wells
During the drilling process, the wellhead of the oil well is easily impacted by the downhole drill bit and eroded by sediment, causing small particles such as sand to enter the well. These small particles can easily cause a decrease in oil well production capacity and damage to wellhead equipment. The emergence of drilling screen pipes can filter ions and excess solid particles, prevent sand erosion, protect the oilfield environment, and maintain the integrity of oil well equipment.
