Description
Technical field
The utility model relates to oil field downhole detection technical field, the special tool that the instrument in particularly a kind of horizontal well downhole detection process is carried.
Background technology
At present, horizontal well recovery ratio problem has become a key factor that influences the oil field overall yield.Operation exploitation along with horizontal well, the part well water rises soon, output descends, and fast situation is serious, thereby how to carry out the horizontal well production logging to understand the down-hole casing degree of impairment in good time, for horizontal well well stimulation optimization provides reliable basis, be the major subjects that the horizontal well engineering log faces.Horizontal well track approaches level, and logger is lowered to method and peupendicular hole has very big difference.Need special technique that logger is sent to the measuring well section in the well logging process, we are referred to as the logger conveying technology with this technology; Along with development of well logging technology, the logger conveying technology also is enhanced, and currently comparatively ripe is: interior the logger conveying technology of oil pipe (drilling rod), coiled tubing conveying and crawl device conveying technology.Shortcomings such as current instrument conveying technology exists the construction technology complexity, and the logging operation time is long, and operating risk is big.If downhole probe at down-hole and card, must carry out unfreezing by instrument.
The utility model content
The purpose of this utility model is: provide a kind of voltage-controlled waterpower to push instrument, be used for sending into of horizontal wellbore logging instrument, realize that the instrument of horizontal well monitoring is carried at downhole safety.
The technical solution adopted in the utility model is: voltage-controlled waterpower pushes instrument, mainly is made up of top connector, support ring, bottom connector, piston and spring; There is screw thread the upper end of top connector, can connect with the instrument polyphone.It is characterized in that: there is the stepped central hole connector lower end, top and transverse holes is arranged, the stepped central hole of top connector and transverse holes UNICOM.Be fixed with support ring in the connector shoulder hole of top, support ring is a disc, and the cylinder of downward protrusion is arranged at the support ring center, on support ring and cylinder week for longitudinal hole is arranged.
There is external screw thread the lower end of top connector, and the top connector is threaded with the bottom connector.The bottom connector is the cylinder bodily form, and the lower end of bottom connector is the end socket of cone shape, and there is centre bore the upper end of bottom connector and transverse holes is arranged, the centre bore of bottom connector and transverse holes UNICOM.In the centre bore of bottom connector upper end piston and spring are arranged, piston can slide in the connector centre bore of bottom, and spring is in lower part of piston.
The cylinder of protrusion is arranged at described piston bottom, and cylinder is inserted in the spring.
Described spring is the compression spring.
Smooth and easy for the highly pressurised liquid circulation, on the outer wall of top connector, guiding gutter is arranged, the transverse holes UNICOM of guiding gutter and top connector.
Smooth and easy for the highly pressurised liquid circulation, on the outer wall of bottom connector, guiding gutter is arranged, the transverse holes UNICOM of guiding gutter and bottom connector.
Voltage-controlled waterpower pushes the operating principle of instrument: consult Fig. 1.This voltage-controlled waterpower propelling movement instrument is used for the horizontal well test job.Voltage-controlled waterpower propelling movement instrument is connected to the instrument string bottom.The whole instrument string leans on gravity down to the position that is hampered.Rely on the ground water filling, making in the tubing string of instrument place increases, and when pressure is enough big, according to F=PS, will promotes instrument and move in horizontal segment, and instrument is delivered to the purpose degree of depth.Transverse holes and stepped central hole inner flow passage at top connector 1 form downward pressure, play to increase the effect that waterpower pushes power.
When the instrument string instrument that especially pushes occurs unusual stuck tubing string with the instrument of propelling movement in pit shaft, pressure increases, when building the pressure to a certain degree, piston 4 moves down, make and form runner in the propelling movement instrument, advance from the transverse holes of top connector 1, go out, avoid waterflood path by the situation of blocking from the transverse holes of bottom connector 3.
In addition, when occurring high-pressure fluid in the well and upwards gush, piston 4 moves up under the effect of high-pressure fluid, when piston 4 moves up the bottom that withstands on support ring 2 when protruding cylinder, fluid forms the highly pressurised liquid runner by the through hole of support ring 2, advances from the transverse holes of bottom connector 3, go out from the transverse holes of top connector 1, thereby improved safety factor.This propelling movement instrument external diameter is seriation, can choose according to different test strings.Spring 5 elastic force also are to choose according to the different pressures demand.
The beneficial effects of the utility model: the voltage-controlled waterpower of the utility model pushes instrument, can push logger in horizontal well, can log well under airtight well head situation.Do not use the pipe operation in the well logging process, the well logging construction risk reduces, and has improved the safety factor in the waterpower course of conveying.Having overcome horizontal wellbore logging can't seat shut-in well in cable is gone into the well process mouthful, can't implement the deficiency of airtight water filling pressurization.
