Horizontal well production monitoring and intelligent control integrated well completion tool and using method

Abstract

The invention relates to a horizontal well production monitoring and intelligent control integrated well completion tool and a using method. The horizontal well production monitoring and intelligent control integrated well completion tool is characterized by comprising an upper connector, a lower connector, an electric control short section, a regulation and control short section and a monitoringshort section, wherein one end of the electric control short section is movably connected with the upper connector, and the other end of the electric control short section is movably connected with one end of a conversion connector; one end of the regulation and control short section is movably connected with the other end of the conversion connector, and the other end of the regulation and control short section is movably connected with one end of a double male connector; and one end of the monitoring short section is connected with the other end of the double male connector, and the other end of the monitoring short section is connected with the lower connector. According to the horizontal well production monitoring and intelligent control integrated well completion tool, the upper connector and the lower connector are separately connected with a production tubular column and lowered into a preset position for fracturing and production, other special lowering tools are not required,the upper connector and the lower connector are not limited by well depth and horizontal segment length, the operation risk is reduced, and the well completion cost is saved.

Description

technical field [0001] The invention relates to a well completion tool integrated with horizontal well output monitoring and intelligent control and its use method, and relates to the technical field of heavy oil development. Background technique [0002] In the field of heavy oil / oil sand development, steam-assisted gravity drainage technology is an advanced technology for mining super-heavy oil and oil sand. SAGD technology was first proposed by Bulter in 1981 to exploit heavy oil / oil sand with dual horizontal wells. The basic principle is to use steam as a source of heat conduction and heat convection to heat formation crude oil, and use steam to expand vertically and laterally in the reservoir to heat formation crude oil, and the heated crude oil and condensate flow to the production well below the oil layer under the action of gravity for extraction , At present, this technology has been widely used in the development of heavy oil in Canada, Liaohe and Xinjiang of my coun...

Problems solved by technology

[0005] In view of the above problems, the purpose of the present invention is to provide a SAGD horizontal well production monitoring and intelligent control integrated completion tool and its use method, equipped with the tool can be lowered to the design position of the horizontal well section along with the completion string, using the downhole The slow flowback of the tracer in the fluid scouring completion tool realizes the interpretation of the production profile of different well intervals in the horizontal well, and realizes the advantages of controlling the flow rate of the produced fluid between different horizontal well intervals and formations by controlling the opening size of the inner sliding sleeve. Solved the problems of long operation cycle, high operation cost and high operation risk of horizontal well production profile monitoring
