Description
Technical field:
The present invention relates to horizontal well even steam injection and shaft mouth test apparatus that a kind of horizontal well heavy oil steam injection recovery is used.
Background technology:
At present, both at home and abroad annotate vapour and test device therefor function all is single at horizontal well, can realize that the horizontal well horizontal segment evenly annotates vapour, can not realize that simultaneously the horizontal well horizontal segment being annotated the vapour effect monitors, the vapour exploitation effect is annotated in influence, thereby influences oil recovery efficiency.The Liaohe Oil Field is badly in need of exploitation and can be realized the horizontal well horizontal segment is evenly annotated vapour and to annotating the corollary equipment that the vapour effect is monitored at any time, annotated the needs of vapour exploitation to satisfy the present level well along with the popularization of horizontal well technology.
Summary of the invention:
The purpose of this invention is to provide a kind of horizontal well even steam injection and shaft mouth test apparatus, this device solves the notes vapour that exists in the prior art and test device therefor function all be single, can not annotate vapour simultaneously and carry out problems of monitoring annotating the vapour effect.
The technical solution adopted for the present invention to solve the technical problems is: horizontal well even steam injection and shaft mouth test apparatus, by casing flange, casing valve, the tubing head four-way, steam injection valve, thick flange main body, the tubing head reducing joint, the oil recovery valve, hang black box, hanger is formed: casing flange, casing valve is that bolt is connected with the tubing head four-way, the tubing head four-way, steam injection valve, the tubing head reducing joint all is connected with thick flange main body bolt, the oil recovery valve is connected with tubing head reducing joint bolt, hang the black box seat in thick flange main body, the hanger seat is all fixed by jackscrew in the tubing head four-way; This device adopts suspended double-pipe middle pipe structure: hang the heavy caliber steam injection string on thick flange main body, small-bore steam injection string is hung in the tubing head reducing joint, and it passes the heavy caliber steam injection string well section that is up to the standard; Hanger hangs the heavy caliber oil pipe, hangs black box and hangs the sealing test tubing string, and test string passes the heavy caliber oil pipe that oblique welding neck flange, thick flange main body and hanger hang, and the well horizontal segment that is up to the standard carries out the test of technical data; Hanger, thick flange main body all adopt two eccentric structures: hanger one eccentric orfice hangs the heavy caliber oil pipe, and another eccentric orfice is a heavy caliber steam injection string passage; Thick flange main body one eccentric orfice hangs the heavy caliber steam injection string, and another eccentric orfice arrives the passage of hanger by thick flange main body for the test string that hangs the black box suspension.Match big small-bore steam injection string size by science, can guarantee that annular space size and small-bore steam injection string latus rectum are complementary between the big small-bore steam injection string, being implemented between the big small-bore steam injection string annular space annotates vapour and annotates vapour by small-bore steam injection string, reach even notes vapour, can realize test simultaneously horizontal well horizontal segment technical data.
The invention has the beneficial effects as follows: this device adopts suspended double-pipe middle pipe structure, the test that when realization is evenly annotated vapour to the horizontal well horizontal segment, can realize novel in design to horizontal well horizontal segment technical data, improve the notes vapour effect of horizontal well greatly, improved oil recovery efficiency.
