Abstract

The invention discloses a low shearing plunger type throttling valve used for oil production gathering and transporting. Based on a rotational flow agglomeration and unit mass energy dissipation rate control technology, orifices of a valve cage are designed to be in the tangential direction, a rotational flow chamber which is converged firstly and expanded afterwards is connected behind the orifices, the basic function of flow and pressure adjustment can be achieved on the plunger type throttling valve, meanwhile, the velocity gradient and the turbulence energy dissipation rate in a flow field are reduced, the shearing force of the orifices for fluid is reduced, the liquid drop breaking degree is lowered, and the subsequent oil water separation difficulty is lowered.

Description

technical field [0001] The invention relates to the field of crude oil exploration, collection and transportation; in particular, it relates to a low-shear plunger-type throttle valve for petroleum exploration, collection and transportation. Background technique [0002] With the continuous development of social economy, energy consumption will increase. In the next 20 years, oil-based traditional fossil energy will still dominate, and the world's major oil companies have to continue to increase their efforts in oil exploration and development. With the gradual increase of production time, the water content in the oil well production fluid of major oilfields is also gradually increasing. At present, the average water content of oil well production fluid in the world has exceeded 80%, and some have even exceeded 95%. The substantial increase in water produced by oil wells has brought a great impact on the oil and gas gathering and transportation process, especially increasin...
