Abstract
The oil well viscosity reducing method for condensed oil production is that condensed oil viscosity reducing agent is produced into solid viscosity reducing block with crude oil passage and certain amount of viscosity reducing blocks are loaded into steel pipe connected to available oil exploiting pipe. When crude oil passes through the solid viscosity reducing blocks, the slowly dissolved viscosity reducing blocks make crude oil emulsified and reduced in viscosity.
Description
The present invention relates to a kind of method of viscosity reducing of oil-field thick-oil oil well production.
Viscous crude accounts for significant proportion in China and part oil field, the world, and is because its colloid, bitumen content are higher, mobile relatively poor.Thereby the exploitation difficulty of viscous crude is bigger.At present, each oil field of China has formed the series of process technology to the exploitation of viscous crude, and the viscosity reducing of heavy oil wells is prolonged with conventional electrical heating method always and mixes the liquid method, wherein mixes the liquid method and comprises and mix thin oil, water and thinner etc.All there is certain problem in these processes, and the electrical heating method investment is big, and power consumption is high, is prone to fault; Need be equipped with ground flow and down-hole mixing stirring technique and mix the liquid rule, invest also greatlyyer, especially small-block oilfield is built ground to mix the liquid flow process very uneconomical.
Purpose of the present invention is exactly a kind of new method that provides at the problem of heavy crude well viscosity reducing, and this method can improve the effect of heavy crude well viscosity reducing effectively, the simple and practical and reduction production investment significantly of production technology.
The object of the present invention is achieved like this, and it is solid viscosity reduction piece that heavy crude thinner is made solid block, and be provided with the crude oil passage on the viscosity reduction piece, goes in the steel cylinder the solid viscosity reduction of some is packaged, and this tube and oil pipe tubing string link and be installed under the pump.When crude stream when the steel cylinder of solid viscosity reduction piece is housed, solid viscosity reduction piece gradual slow dissolving makes the emulsification of crude oil viscosity reduction, thereby reaches the purpose of well wellbore viscosity reduction.
The inventive method makes the heavy oil wells viscosity reducing more simple, effective.Compare with electrical heating method, this method energy free consumes, expense is low, investment is little, safe and reliable; Compare with mixing the liquid method, this method need not ground flow and down-hole mixed stirring device, and production management is simple, compare, and this method need not ground flow and down-hole mixed stirring device, and production management is simple, investment is little, economical and practical.
The present invention will be further described below in conjunction with accompanying drawing:
Accompanying drawing is the schematic diagram of the inventive method.
Heavy crude thinner is made solid viscosity reduction piece by certain method, the solid viscosity reduction piece 3 of some is packed in the steel cylinder 4, steel cylinder 4 connects with oil pipe 2 tubing strings, be installed on below the pump 1, when crude oil 5 passes through in steel cylinder 4, the dissolving of solid viscosity reduction piece 3 gradual slows makes emulsification of crude oil, thereby reaches the purpose of well wellbore viscosity reduction.
Claims (2)
1, a kind of method of well wellbore viscosity reduction is characterized in that solid viscosity reduction piece, packs in the steel tube and places under the oil pump.
2, the described solid viscosity reduction of claim 1 piece is characterized in that it being that heavy crude thinner is made solid block by certain method, and difform passage is arranged.
