Abstract
The invention provides an orientated measurement guiding butt joint device, belonging to the field of supporting equipment of an orientated perforator for oil and gas well. The device comprises a device body, a magnetic key, a guiding key and a sand discharge groove, wherein the outer side of the upper part of the device body is provided with external thread; the inner side of the lower part of the device body is provided with internal thread; the upper end of the inner side of the device body is provide with the magnetic key; the lower end of the inner side of the device body is provided with the guiding key; and the sand discharge groove is arranged around the device body between the guiding key and the internal thread. The device body and guiding key are of a cylindrical structure respectively; the sand discharge grooves are three symmetrical structures of two semicircles clamping a cuboid; and the lower end of the sand discharge groove is provided with a taper angle. The orientated measurement guiding butt joint device is applied to the measurement guiding butt joint during the butt joint with a gyroscope in the orientated measurement of an oil and gas well.
Description
Technical field:
The present invention relates to oil gas well oriented perforator corollary equipment field, relate to the measurement guiding docking facilities that docks with gyroscope when a kind of orientation is measured concretely.
Background technology:
At present oriented perforator in well hole deviation and orientation determine rely on the well logging gyroscope to measure, the well logging gyroscope is transported to the down-hole by cable, fix with orientation pipe nipple realization automatic butt, make gyroscope and oriented perforation tubing string form one, data such as hole deviation that gyroscope is measured and orientation are the hole deviation and the orientation of oriented perforation tubing string, after measurement is finished, last portable cable, the well logging gyroscope can withdraw from and being connected of orientation pipe nipple automatically.But existing orientation pipe nipple adopts rectangle to guide key into, and its frictional resistance is big, and the butt joint success rate is low, and the top sand hole that begins to rehearse be prone to phenomenons such as sand plug, and whether successfully butt joint can't ground monitoring.
The utility model content:
Purpose of the present invention is intended to overcome the deficiencies in the prior art, provide a kind of solve butt joint monitor in real time, guide into that the key frictional resistance is big, the butt joint success rate is low, be prone to the sand plug problem simple in structure, connect orientation fast and easily and measure the guiding docking facilities.、
Purpose of the present invention can realize by following technical measures:
This orientation is measured the guiding docking facilities and is made up of body, magnetic key, feather key and sediment outflow groove, the body upper outside is provided with external screw thread, lower inside is provided with internal thread, the body inner top side is provided with magnetic key, inside lower end is provided with feather key, is provided with the sediment outflow groove around the body between feather key and the internal thread.
Purpose of the present invention also can realize by following technical measures:
Described body and feather key are respectively cylindrical structure; Described sediment outflow groove is symmetrical 3 roads two semicircles folder rectangular structure, and the bottom is provided with cone angle; Described magnetic key is arranged in the shell of body; The inner chamber of the corresponding body of described magnetic key is opened circular hole.
Orientation of the present invention is measured the guiding docking facilities and is adopted the built-in feather key of cylinder, makes the face Frotteurism of former butt joint become the line friction, reduces frictional resistance, and the guiding gyroscope is successfully butt joint with it; The instrument magnetic orientation correspondence position inboard that is about to enter mated condition at gyroscope is provided with magnetic key, can accurately judge the butt joint success or not by the magnetic signal that ground collects; Change clean clearance hole as 45 ° of sediment outflow grooves that are arranged on the body bottom into, hole deviation is big or pit shaft is dirtier causes docking when getting nowhere, and can circulate to clean by oil jacket and carry the tubing string inner space more than the sediment outflow groove, or achieve a butt joint with the method for pumping.
Body upper outside of the present invention is provided with standard external, is used to connect oil pipe, and the inboard, lower end is provided with standard female, is used to connect priming device; The body inner top side is provided with magnetic key, and magnetic key is embedded in the body inboard, and is lower than inner surface, has magnetic, when gyroscope docks with the orientation pipe nipple, can change determining whether to dock successfully by the magnetic signal of gyroscope survey; The body inside lower end is established cylinder bodily form feather key, and the guiding gyroscope docking and fixing with the orientation pipe nipple, and the face friction when the cylindrical structure design of feather key will be docked is converted to linear friction, improves the butt joint success rate; Establish symmetrical 3 roads two semicircles folder rectangular structure sediment outflow groove around the body between the inboard standard female in feather key and lower end, and 45 ° of cone angles of bottom design.It is located at can reduce bottom and the sand plug phenomenon occurs, is used for that the big or pit shaft of hole deviation is dirtier to be caused docking when unsuccessful, can clean perforation tubing string obstruction, has improved the success rate of construction, has satisfied the demand of pumping butt joint simultaneously.The present invention makes gyroscope dock success rate with the orientation pipe nipple to reach 100%, has improved the success rate of oriented perforation construction.It is simple in structure, reasonable in design, connects efficient and conveniently, is easy to realize.
Description of drawings:
Fig. 1 is the structural representation of the embodiment of the invention.
The specific embodiment:
With reference to accompanying drawing: the present invention is made up of body 1, magnetic key 2, feather key 3 and sediment outflow groove 4.Body 1 is a cylinder, and body 1 upper outside is provided with standard external 101, and the inboard, lower end is provided with standard female 102; Body 1 inner top side is provided with magnetic key 2, and magnetic key 2 is embedded in body 1 inboard; Body 1 inside lower end is established cylinder bodily form feather key 3; Establish symmetrical 3 roads two semicircles folder rectangular structure sediment outflow groove 4 around the body between the inboard standard female 102 in feather key 3 and lower end, and 45 ° of cone angles of bottom design, magnetic key 2 is arranged in the shell of body 1, and the inner chamber of magnetic key 2 corresponding bodies 1 is opened circular hole.
