Abstract
The utility model relates to a continuous pipe well logging coil pipe device used for horizontal well logging operation, and continuous pipe well logging coil pipe the device is composed of a shell, a guard plate, clamping wheels, a fixing bolt, a measurement wheel, a photoelectric encoder and a bracket. The shell and the guard plate are arranged at the outer sides of two pairs of clamping wheels which are oppositely arranged at the upper part and the lower part and are fixed by the fixing bolt. The measurement wheel is arranged between the two clamping wheels at the upper part, and the photoelectric encoder is coaxially arranged with the measurement wheel. The middle point of the lower part of the shell and the guard plate is fixed at the upper end of the bracket at the lower part. The continuous pipe well logging coil pipe device has the advantages of simple structure, convenient assembly and disassembly and reliable work. By utilizing the continuous pipe well logging coil pipe device, the depth information of a continuous pipe and a downhole logging tool can be accurately recorded in the process of the horizontal well logging operation in real time to ensure the normal proceeding of the well logging operation.
Description
Technical field:
The utility model relate to a kind of be used for oil well particularly horizontal well manage the device that the logging operation process provides continuous pipe and the downhole probe speed of service and depth information continuously.
Background technology:
The pipe logging technique is to utilize the characteristics of pipe high strength, high tenacity continuously continuously, downhole instrument is sent into the net horizontal section of horizontal well and is tested.Continuously pipe twists on the cylinder, and the rotation by index drum drives removing of continuous pipe, can guarantee that downhole instrument tests continuously.The stratum physical parameter that logging operation is measured by downhole probe, and by a certain percentage with the continuous change records record of well depth.Therefore, the depth information of downhole instrument is the basis of logging operation, is mechanical type degree of depth metering device and the at present on-the-spot continuous pipe working rig that uses adopts, can not satisfy the requirement of logging operation.
The utility model content:
The purpose of this utility model be to provide a kind of can be in the horizontal wellbore logging operation process accurate recording continuous pipe well logging coil pipe device of pipe and the downhole logging instrument device degree of depth continuously in real time.
The utility model is to realize like this.This kind coil pipe device is made up of clamping wheel, meter wheel, shell and backplate, photoelectric encoder, set bolt and support, and upper and lower two pairs of clamping wheel outsides that are oppositely arranged are provided with shell and backplate, and are fixed with set bolt; Be provided with meter wheel in the middle of two the clamping wheels in top, on meter wheel is coaxial photoelectric encoder be housed; Shell and backplate bottom midpoint are fixed on the support upper end of below.Before the logging operation, the support of this device bottom is installed on the continuous pipe rolling stand, continuous pipe is passed from the two pairs of clampings wheel of this coil pipe device, and be held wheel and tightly clamp, meter wheel tightly is pressed on the continuous pipe, is keeping the state that is synchronized with the movement with continuous pipe.In the logging operation process, continuously pipe begins to do and removes motion, driving clamping wheel and meter wheel simultaneously does and is synchronized with the movement, the photoelectric encoder meter wheel coaxial with meter wheel rotates synchronously, and generation electronic pulse signal, by holding wire pulse signal is delivered to well logging and handle in the ground installation, thereby obtain the depth information data in real time, exactly, guarantee normally carrying out of logging operation.
The utility model is simple in structure, and assembly and disassembly is convenient, and reliable operation utilizes it to write down pipe and downhole logging instrument device depth information continuously in real time, exactly in the horizontal wellbore logging operation process, guarantees normally carrying out of logging operation.
Description of drawings:
Fig. 1 is this novel side structure schematic diagram.
Fig. 2 is its top front face structure enlarged diagram.Among the figure, label " 7 " is continuously a pipe.
The specific embodiment:
As shown in the figure, the utility model is made up of shell and backplate 1, clamping wheel 2, set bolt 3, meter wheel 4, photoelectric encoder 5 and support 6, its structure, assembled relation are as follows: upper and lower two pairs of clampings that are oppositely arranged are taken turns 2 outsides and are provided with shell and backplate 1, and fixed with set bolt 3, be provided with meter wheel 4 in the middle of two clampings in the top wheel, on meter wheel 4 is coaxial photoelectric encoder 5 be housed; Shell and backplate 1 bottom midpoint are fixed on support 6 upper ends of below.Wherein, shell and backplate 1 is recessed in the middle of its both sides, top projection for the box-shaped body that shape, size and two pairs of clamping wheels 2 and middle meter wheel 4 are complementary.Clamping wheel 2 totally 4 is divided into the left and right sides, and 2 shapes, measure-alike are taken turns in 4 clampings, and wheel rim is processed into semi-circular recesses, and upper and lower two-wheeled is combined into circular space relatively and penetrates for continuous pipe.Meter wheel 4 diameters are a bit larger tham clamping wheel 2, the coaxial photoelectric encoder 5 that is provided with.
