DEVICE FOR RESEARCH multilateral wells coiled tubing

摘要

The proposal relates to the oil industry, in particular, to devices for the delivery of geophysical instruments in sidetracks multilateral wells for the purpose of study. An apparatus for the study of multilateral wells using coiled tubing includes a body with a central passageway, a spherical sample from below and the inner groove in the middle part. In the internal bore casing inserted in an axially displaceable spring loaded downwards by a spring upwards from the piston rod, fitted with a central passageway. The apparatus also includes a deflecting head with a hemisphere on top, cooperating with a pivotable deflection and with the lower part of the spherical body sample. Deflection head is spring-loaded by a spring from the housing. In the housing between the deflecting head and the rod is mounted eccentric hollow blank. The eccentric hollow lower abutment portion is inserted telescopically inside the deflecting head and the upper end cooperates with a rod. Top outside eccentric hollow hemisphere equipped abutment ending bottom segment. Eccentric hollow hemisphere abutment cooperates with the upper part of the spherical body sample. Segment eccentric hollow abutment cooperates with the upper plane of the hemispherical head deflection to deflect the latter while moving with the piston rod downwards. In order to avoid "porshnevaniya" in the device operation process on the lower end of the inner body bore formed process opening. Bottom deflecting head is equipped with a nozzle orifice. The bottom is attached to the nozzle cable head, fitted with a bottom geophysical instruments. geophysical instrument cable passed through the interior of the device and sealed by a sealer in the cable head. The proposed device has a simple structure, low cost, and the extension of its functional capabilities associated with the possibility of working in horizontal directional and horizontal wells. In addition, it allows to deliver geophysical instruments such as the meter, thermometer and others, sidetracks multilateral well, which allows investigation of multilateral wells. 2 yl. to 1 liter.
