Background technology
In gas well manufacturing process, after the formation water of the high salinity of stratum output mixes with natural gas, under hot conditions, easily in oil pipe, there is chemical reaction, cause bottom oil pipe fouling in well.After the fouling of gas well oil pipe, pipe aperture size decreases, can seriously jeopardize test jobs safety.At present, in gas well well logging and well testing operation, because causing the instrument well accident that falls, oil pipe fouling often occurs.In addition,, after oil pipe fouling, once pipe aperture narrows down to a certain degree, will affect the production of gas well and carrying out of drainage measure.The adverse effect causing for fear of oil pipe fouling, need carry out to oil pipe the research of antiscaling, descaling.Yet there is no at present special oil pipe fouling prospecting tools, thereby can not understand fouling situation and the scaling rule of OIH pipe, be inconvenient to carry out the research of antiscaling, descaling, thereby, a oil pipe fouling prospecting tools of exploitation be badly in need of.
Summary of the invention
The object of the present invention is to provide a kind of can be for the fouling situation of detecting shaft inner oil tube and the oil pipe fouling prospecting tools of scaling rule, so that carry out the research of antiscaling, descaling.
To achieve these goals, the present invention adopts following technical scheme: oil pipe fouling prospecting tools, the main body that comprises downward-extension, in main body, be provided with cavity, main body is provided with one or at least two and runs through cavity and upper and lower spaced shop bolt, in cavity, in the bottom of shop bolt, be provided with for cutting off the cutting member of shop bolt, the bottom of cutting member is provided with for upwards holding out against the elastic ring of cutting member, elastic ring is axially set in main body along main body, and the bottom of elastic ring has the fixed connection structure for being fixedly connected with main body.
In main body, be also provided with for connecting the fixed installation structure of vibrating device.
The top of described cutting member is provided with up and down movably righting connecting rod, and righting connecting rod is provided with the slotted hole of downward-extension, and described shop bolt is threaded onto in slotted hole.
The bottom of described main body is installed with guide head, and the bottom of described guide head is pyramidal structure.
Described main body and guide head are threaded connection and are fixed together.
The bottom of described main body offers fixed installation groove, and described fixed connection structure is fixed together by fixed installation groove and main body.
Described fixed installation structure is screw thread structure.
Described cutting member is shear pin or shear-blade.
Beneficial effect of the present invention: this oil pipe fouling prospecting tools in use, oil pipe prospecting tools is transferred in well, in folding process, when if instrument is hampered, record the position that is hampered, cutting member is cut off corresponding shop bolt, elastic ring radially inwardly shrinks along main body, elastic ring can apply active force upwards to cutting member, thus cutting member shop bolt can be cut off, then continue test.By the change in location that is hampered several times of this instrument, can draw out the linearity curve of oily in-tube fouling situation, thereby can understand the fouling situation in oil pipe, and then can carry out the research of antiscaling, descaling.
Further, because main body is provided with fixed installation structure, thereby, this instrument is before using, can vibrating device be connected on oil pipe prospecting tools by fixed installation structure, when instrument is hampered, by vibrating device, to cutting member, be applied with lower effect of vibration power, cutting member can, by shop bolt quick shearing, can improve detection efficient.
Further, the slotted hole on righting connecting rod has the guide effect of above-below direction to cutting member.
Further, guide head bottom is pyramidal structure, in guide head folding process, the obstacle in oil pipe can be removed, and the instrument of being convenient to moves down.
