Well head mud removing device

Abstract

The invention provides a well head mud removing device. The well head mud removing device comprises a primary rotational flow device and four secondary rotational flow devices, wherein the four secondary rotational flow devices are uniformly distributed at the periphery of the primary rotational flow device, and the top of the primary rotational flow device is communicated with the four secondary rotational flow device through a shunt manifold; the lower ends of the primary rotational flow device and the four secondary rotational flow device are all connected with a mud discharging pipeline; outlets in the tops of the four secondary rotational flow devices are communicated through a gathering pipeline. According to the well head mud removing device, two stages of separation is realized through the combination of four rotational flow mud removing machines instead of one rotational flow mud removing machine, and each stage of mud removing effect is effectively improved through different rotational flow difficulties, handling capacity and matched inlet and outlet manifolds of the two stages of rotational flow devices. According to the device, not only can the mud filtering effect of the well head mud removing device be improved, but also downstream equipment can be protected effectively.

Description

technical field [0001] The invention relates to the protection technology for downstream equipment in the fields of oil and gas field exploration and development, ground testing, test production operations, sand discharge and gas recovery operations, and post-pressure flowback operations. Background technique [0002] Various types of desanders are widely used in oil and gas field exploration and development to better protect downstream equipment and complete production tasks with higher construction quality. [0003] At present, the widely used cyclone desander has been tested on the ground and flowback after fracturing. It is found that the particle size of the mud and sand produced by the oil and gas well is too small, resulting in poor desilting effect, so that the construction quality cannot be effectively guaranteed. [0004] In recent years, the exploration and development technology and technology of Changqing Oilfield have been continuously improved, and the product...

AI Technical Summary

Problems solved by technology

[0005] In order to overcome the problem that the treatment effect of the existing mud and sand with smaller particle size (15-74 microns) is not ideal, and the original sand remover can no longer fully meet the requirements of high-efficiency filtration of mud and sand in the flowback liquid, the present invention provides a A kind of wellhead desilting device, this device can effectively filter out solid particles such as mud and sand, and the desilting efficiency is as high as 90%, which largely avoids the damage of mud and sand to the downstream equipment on the ground
