Abstract
The utility model relates to a sleeve pipe window opening orientation device of a radial horizontal well, which is mainly used for the orientation of the sleeve pipe window opening direction in the radial horizontal well operation so that the injection stratum operation in the later period is drilled in the preliminarily designed direction. The sleeve pipe window opening orientation device mainly consists of a gyro inclinometer guide shoe, a body joint, a lining sleeve, a fastening screw and a guide device. The utility model is characterized in that the lining sleeve with a track guide groove is arranged in the body joint, the gyro inclinometer guide shoe is matched and connected with the lining sleeve, the body joint is connected with the guide device through screw threads, and in addition, the orientation between the guide device and the body joint is fixed through the fastening screw. When the sleeve pipe window opening orientation device of the radial horizontal well provided by the utility model is used, the smooth downwards placing and outwards lifting underground tools in the later period can be ensured, and meanwhile, the precision of the orientation angle measurement at an outlet of the guide device can be better ensured.
Description
Technical field: the utility model belongs to the petroleum machinery technical field, especially relates to a kind of radially horizontal well casing pipe bearing unit of windowing, and is mainly used in the orientation in radial level well operations casing sidetracking orientation.
Background technology: at present in the peupendicular hole oriented perforating, be and directly in the perforation tubing string, be welded with a key position, when being lowered to gyrolevel, automatically import the orientation gathering sill of gyrolevel tail end on the key position by the orientation short circuit in the perforation tubing string, make gyrolevel constitute an integral body with the perforation tubing string, be in linkage status, by rotate the orientation that oil pipe is adjusted the oriented perforating device on ground, make it consistent then with the perforation orientation of setting.
Technological requirement in conjunction with the radially horizontal well drilling well, the bearing unit of above oriented perforating has the following disadvantages: the key position that in tubing string, welds will influence the later stage downhole tool be lowered to and trip out, might make downhole tool that the card phenomenon takes place to meet, if and in a single day key position be subjected to bigger shock loading, have cut off may.
Summary of the invention: the purpose of this utility model is to provide a kind of radially horizontal well casing pipe bearing unit of windowing, and guaranteeing being lowered to smoothly and tripping out of later stage downhole tool, and the orientation that guarantees casing sidetracking is with to design the orientation consistent.
Technical solution adopted in the utility model is: a kind of radially horizontal well casing pipe bearing unit of windowing, this bearing unit mainly is made of gyrolevel guide shoe, main body joint, lining, holding screw and guider, it is characterized in that in the main body joint, being equipped with the lining of band track gathering sill structure, gyrolevel guide shoe and lining are connected, the main body joint is connected with guider by screw thread, and with the orientation of holding screw fixed guider and main body joint.
Bearing unit of the present utility model, during main body joint interior welds lining, guarantee the most advanced and sophisticated center line of aiming at main body joint outside keyway of lining, main body joint and guider are by being threaded, guarantee that when connecting guider center line of discharge and main body joint outside keyway center line are on same straight line, and fix with holding screw, so the most advanced and sophisticated orientation of lining is consistent with guider outlet orientation, then is the azimuth that guider exports with the measured azimuth of gyrolevel on the ground.
Bearing unit of the present utility model, because of between the track gathering sill of the track gathering sill of gyrolevel guide shoe and main body joint inner liner for the inclined-plane cooperates, cooperate tightr, so the azimuth that records is also more accurate; The lining of main body joint inside is a track gathering sill structure in addition, and that can avoid the later stage downhole tool is lowered to and trips out contingent chance card phenomenon in the process.
Description of drawings:
Fig. 1 is the radially horizontal well casing pipe bearing unit schematic diagram of windowing;
(1) gyrolevel guide shoe wherein, (2) are the main body joint, and (3) are lining, and (4) are holding screw, and (5) are guider.
Fig. 2 is a gyrolevel guide shoe structural representation among Fig. 1;
Fig. 3 is a bush structure schematic diagram among Fig. 1;
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing.By shown in Figure 1, the utility model comprises gyrolevel guide shoe (1), main body joint (2), lining (3), holding screw (4), guider (5).It is characterized in that being equipped with in the main body joint (2) lining (3) of band track gathering sill, gyrolevel guide shoe (1) is connected with lining (3), main body joint (2) is connected with guider (5) by screw thread, and with the orientation between holding screw (4) fixed guider (5) and main body joint (2).
Utilize the radially horizontal well casing pipe of the present utility model bearing unit of windowing to guarantee being lowered to smoothly and tripping out of later stage downhole tool, also can better guarantee the accuracy of guider outlet azimuth determination simultaneously.
Claims (2)
1. radially horizontal well casing pipe bearing unit of windowing, comprise: gyrolevel guide shoe (1), main body joint (2), lining (3), holding screw (4), guider (5), it is characterized in that being equipped with in the main body joint (2) lining (3), gyrolevel guide shoe (1) is connected with lining (3), main body joint (2) is connected with guider (5) by screw thread, and with the orientation between holding screw (4) fixed guider (5) and main body joint (2).
