Forced cooling system for petroleum drilling fluid

Abstract

The invention discloses a forced cooling system for petroleum drilling fluid, which relates to the technical field of auxiliary devices of petroleum drilling equipment. The forced cooling system comprises a bracket and a fluid cooling tank, wherein the bracket has a rectangular frame structure with an upper opening; the fluid cooling tank comprises a tank body, a bottom frame, a filler layer, a cooling fan, a spraying system, a fluid collecting tank and a discharging tank; the cooling fan is arranged right above the filler layer; the fluid collecting tank is arranged just under the filler layer; the discharging tank is butted with the fluid collecting tank; the spraying system is fixedly arranged between the filler layer and the cooling fan; a fluid conveying pump is fixedly arranged at the bottom of the bracket; and a discharging hole of the fluid conveying pump is butted with a feeding hole of the spraying system through a fluid conveying pipe. The forced cooling system has the advantage of realizing the aim of reducing the fluid temperature to reach a normal drilling level by virtue of a forced air-cooling structure and by means of the structural features of the forced cooling system.

Description

technical field [0001] The invention relates to the technical field of an auxiliary device for oil drilling equipment. Background technique [0002] In the process of oil drilling, the drilling tool cutting rock can generate a lot of heat, and the friction between the drilling tool and the hole wall generates a lot of heat, and with the increase of the drilling depth, the ground temperature at the bottom of the hole also gradually increases, and this heat is transferred to the mud. When it is taken out of the well, the temperature of the mud gradually increases. The increase of the temperature of the mud will cause certain corrosion to the drilling tools and conveying equipment, shorten the service life of the drilling tools, and also affect the mud composition and the effect of the mud. Drilling uses the mud configured according to the geological conditions, and the cost is high. In order to prevent the high-temperature mud from repeatedly entering the bottom of the hole an...

Problems solved by technology

[0002] In the process of oil drilling, drilling tools can generate a lot of heat by cutting rocks, and at the same time, the friction between drilling tools and the hole wall will generate a lot of heat, and as the drilling depth increases, the ground temperature at the bottom of the hole will gradually increase, and the heat will be transferred to the mud. At the same time, the temperature of the mud is gradually increased. The increase of the mud temperature will cause certain corrosion to the drilling tool and the conveying equipment, shorten the service life of the drilling tool, and also affect the mud composition and mud function. Drilling uses mud configured according to geological conditions, and the cost is high. In order to prevent high-temperature mud from repeatedly entering the hole bottom and mud recycling, the current construction adopts the route of extending the mud tank to make the mud cool down naturally in the circulation flow, and the cost is high. And it occupies a large area
