Abstract
The utility model relates to a well-logging device of a sleeve horizontal well, comprising a cable, a rotating short section, an upper transferring short section, an upper centralizer, a retractor, a center centralizer, a lower transferring short section, a flexible short section, a well logger and a lower centralizer. The rotating short section, the upper transferring short section, the upper centralizer, the retractor, the center centralizer, the lower transferring short section, the flexible short section, the well logger and the lower centralizer are connected with each other in turn from top to bottom. The upper end of the rotating short section is connected with the cable. The upper end of the cable is separately connected with a computerized well-logging surface system and ground control power supply equipment. The well-logging device has reasonable design and new structure, which can simply and conveniently lower the well logger to surveying section by the high efficiency of the retractor, and therefore the successful process of the well-logging work of the sleeve horizontal well can be ensured. The device has advantages of less application equipment, simple operation, good work efficiency, high data accuracy, etc.
Description
Technical field:
The utility model relates to a kind of downhole hardware that is used for the horizontal wellbore logging operation, belongs to oil well logging downhole tool class.
Background technology:
Along with the development of development technology in oilfield technology, horizontal well is used scale and is enlarged day by day, and the well number is more and more.Conventional logging technique technology adopts cable to carry the mode of downhole instrument, in instrument is gone into the well process, mainly relies on the effect that focuses on gravity certainly of downhole instrument and cable to fall down.This technology is mainly used in the logging operation of straight well or gradient inclined shaft within the specific limits.Because horizontal well casing programme more complicated in horizontal case well and big gradient cased hole logging process, can't make instrument be lowered into horizontal target zone by the instrument self gravitation.At present, no matter on-the-spot well logging project of carrying out in the sleeve water horizontal well is to put magnetic logging, engineering log, dynamic monitoring or remaining oil saturation well logging admittedly, and the method for employing mainly contains three kinds: the wet joint method, pump method and guardrail method.These three kinds of methods all are to finish the collection of data by drilling, though success rate is higher, drilling and the long well time that accounts for are all caused very big cost waste to drilling crew.Simultaneously, drilling also can strengthen the casing wear degree of drilling tool to high angle hole section and net horizontal section, and duty cycle is long continually, and labour intensity is big, and security control is relatively poor.
The utility model content:
The purpose of this utility model is to provide a kind of can finish the horizontal wellbore logging operation convenient, efficiently, economically, overcome the sleeve water horizontal well well logging apparatus of the shortcoming and defect that traditional drilling rod delivery technology exists.
The utility model is to realize like this.This kind well logging apparatus is made up of cable, upper, middle and lower centralizer, upper and lower conversion pipe nipple, rotating short-knot, flexible pipe nipple and tractor, the order that assembles successively from top to bottom be rotating short-knot, on change pipe nipple, go up centralizer, tractor, middle centralizer, change pipe nipple, flexible pipe nipple, logging instrument, centralizer down down, the upper end is connected with the Ground Control power supply unit with well logging numerical control ground system respectively by cable.In the horizontal wellbore logging process, this device is transferred in the well by cable, when logging instrument is transferred to the well section of constant slope, can't continue to transfer to the measuring well section by gravity, at this moment, send instruction by ground control system, open four draft arms of tractor, make four road wheels tightly be pressed on the casing wall, ground control system is by instruction simultaneously, control main motor and walk along casing wall by four road wheels that a cover mechanical driving device drive is contained on four draft arms, the direction of walking and speed can be controlled by ground system, thereby logging instrument is transported to assigned address.After instrument arrived the position of logging well, ground control system stopped walking by instruction control tractor, regains draft arm, and ground system disconnection tractor power supply will be powered and signal bus switches to the downhole logging instrument device; Logging tasks is finished in logging instrument energising work.The rotating short-knot that adopts in this device is used for preventing that logging instrument from killing knot, the instrument accidents such as well that fall in distraction procedure because of rotation causes cable, and flexible pipe nipple makes instrument can pass through the down-hole inclination section smoothly with hand, changes pipe nipple and is used for connection between each parts.
The utility model is reasonable in design, novel structure, utilize tractor efficiently, quickly thereby logging instrument is guaranteed carrying out smoothly of sleeve water horizontal well logging operation down to the measuring well section, this device has that application apparatus is few, easy and simple to handle, work efficiency and data accuracy advantages of higher.
