Description
Technical field
The utility model relates to horizontal well production logging appearance pusher, belongs to oilfield horizontal well production logging corollary apparatus technical field.
Background technology
At present, the horizontal well test presents increase trend, and along with the increase of hole deviation angle, the test technology of conventional peupendicular hole has satisfied not the test needs.When the production logging appearance is transferred to the well section of constant slope, can't continue to transfer to the measuring well section, at this moment need a kind of instrument that the production logging appearance is transported to the precalculated position by gravity.
In the prior art, horizontal wellbore logging mainly contains pipe and carries method, crawl device conveying method.Pipe conveying method is that the production logging appearance is connected pipe (like the coiled tubing) top that inside is installed with logging cable; Well head adopts a cover hydraulic pressure injected system that power is provided; Pipe is conveyed into well; Send to purpose well section to the production logging appearance, and drive production logging appearance completion well logging by carrying on the pipe or transferring, the method floor conveying equipment is huger, speed slow, degree of depth departure can not be with more greatly, generally speaking and press construction.Disclose a kind of horizontal wellbore logging transport like ZL200920021432.5, mainly formed, be fixed with sleeve pipe in the oil well by water injection pipe, oil pipe, sleeve pipe, well logging apparatus, water pump, screen casing, outlet pipe; Place oil pipe in the sleeve pipe, the top of oil pipe is connected with screen casing, and the production logging appearance is connected with cable; Be positioned in the oil pipe, before the test, need supporting water injection pipe and oil pipe to test; Thereby; Change the tubular column structure of testing well, the fluid state in the testing well is changed, influenced precision of test result; Crawl device conveying method is also referred to as downhole tractor and carries method; Adopt the conventional logging wellhead assembly, connect crawl device (downhole tractor) in production logging appearance rear end, crawl device is connected with logging cable; The peupendicular hole section leans on production logging appearance weight to transfer naturally; After entering inclination section instrument stops, starting working, provide power that the production logging appearance is transported to purpose well section by crawl device and log well through logging cable power supply and control crawl device.Because crawl device is to adopt frame for movement such as motor to promote the production logging appearance; When the shaft bottom exists desilting or seam, hole, can make crawl device push the failure of production logging appearance, so this method transmitting power is less; The pit shaft technical condition are had relatively high expectations; Construction risk is bigger, and generally in the horizontal well casing pipe production logging, uses, and can only go up and survey or the some survey.
Summary of the invention
The purpose of the utility model is to overcome that the construction risk that above-mentioned prior art exists is big, the defective of test result poor accuracy, and a kind of horizontal well production logging appearance pusher is provided.
The purpose of the utility model is achieved in that
The utility model device is made up of top connection, linear electric motors, body, capsule, tail cone; The upper/lower terminal of top connection is connecting thread; On its lower surface, be welded with a motor tube; Linear electric motors adopt dowel fixes in the motor tube, and linear electric motors connect with electricity cable through the centre bore in the top connection; Body is the tubular body that is provided with stepped centre bore; Piston on the linear electric motors inserts in the centre bore of body, and the body upper end is connected with top connection through screw thread, and the lower end is connected with tail cone through screw thread; On the tube wall of the middle part of body, have discharge orifice, and be provided with outside draw-in groove; The tail cone upper end is provided with an annular groove; Capsule is connected between the annular groove of outside draw-in groove and tail cone on the body.
The beneficial effect of the utility model is: when carrying out the horizontal well test, can control the keying of the utility model linear electric motors at well head, propelling movement production logging appearance gets into the measuring well section smoothly and tests, and construction technology is simple, easy to operate, and is safe and reliable, and cost is low.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
The specific embodiment
Shown in accompanying drawing 1; The utility model device is made up of top connection 1, linear electric motors 3, body 6, capsule 8, tail cone 10; The upper/lower terminal of top connection 1 is connecting thread; On its lower surface, be welded with a motor tube 2, linear electric motors 3 adopt pin 12 to be fixed on motor tube 2 inside, and linear electric motors 3 connect with electricity cable through the centre bore in the top connection 1 11; Body 6 is for being provided with the tubular body of stepped centre bore; Piston 4 on the linear electric motors 3 inserts in the centre bore 14 of body 6, and body 6 upper ends are connected with top connection 1 through screw thread, and the lower end is connected with tail cone 10 through screw thread; On the tube wall of the middle part of body 6, have discharge orifice 5, and be provided with outside draw-in groove 7; Tail cone 10 upper ends are provided with an annular groove 9; Capsule 8 is connected between the annular groove 9 of outside draw-in groove 7 and tail cone 10 on the body 6.
Described motor tube 2 internal diameters are greater than the centre bore internal diameter of top connection 1, and its external diameter is less than top connection 1 external diameter.
Between piston 4 on the described linear electric motors 3 and the centre bore 14 on the body 6 sealed packing 13 is installed.
Described body 6 is fixing by pin 15 with the threaded connection place of tail cone 10, avoids tail cone 10 to thread off.
Described tail cone 10 lower surfaces are circular arc, can effectively avoid the production logging appearance in transferring process, to be hampered.
When carrying out the horizontal well test jobs, production logging appearance lower end screw thread is connected with the utility model top connection 1, transfer the entering pit shaft by cable.Excessive when hole deviation, cause the production logging appearance to be hampered in the time of can't arriving the measuring well section smoothly, start linear electric motors 3 at well head, make its driven plunger 4 descending, close the discharge orifice 5 on the body 6.Construct through gaslift; Make the capsule 8 up and down effect of pressure reduction expansion down in well, press close to the test string inwall, when difference force during greater than the frictional resistance of production logging appearance and borehole fluid and tubing string inwall; The production logging appearance is descending along test string, can it be transported to predetermined test position.After test finished, start-up control linear electric motors 3 made driven plunger 4 up, open the discharge orifice 5 on the body 6, made the inside and outside UNICOMs of body 6, reduced the pressure reduction of capsule 8 about, and capsule 8 shrinks, on carry the production logging appearance, can be with its proposition smoothly in the well.
