Abstract
The utility model relates to a positioning tool for drilling dual horizontal wells, in particular to a signal generator of a magnetic source. In the utility model, a power joint (2) is arranged on an upper joint (1) and is connected with a coil (4). The coil (4) is wound on a body (3), the outer surface of the turn of the coil (4) is sealed by using insulated hard rubber (5), and a magnetic field is generated when an alternating power supply passes through the coil (4). A rubber stopper (7) is sleeved on a rubber stopper seat (6) and is a unidirectional rubber stopper with wings. A lower joint (8) is connected on the rubber stopper seat (6) by screw threads and fixes the rubber stopper (7). By the utility model, the field operation is simple, the introduction of a signal source is realized by hydraulic pressurization, the sealing of the insulated hard rubber is favorable, and the coil can be effectively protected.
Description
Technical field
The utility model relates to field of oil drilling, and a kind of pair of orientation tool that horizontal well drilling is used particularly relates to a kind of magnetic source signal generator, belongs to the downhole tool class.
Background technology
Viscous crude occupies bigger ratio in World's Oil and Gas Resources, be the important component part in the petroleum hydrocarbon energy.Boring the parallel horizontal well of a pair of horizontal segment near the oil reservoir bottom position, steam injection of upper water horizontal well and crude oil generation interchange of heat, the crude oil of heating and steam condensate (SC) are by action of gravity earial drainage output in the level of production well of bottom, and this technology can increase substantially recovery ratio.The magnetic orientation measuring technique can accurately be controlled the relative orbit position of two horizontal well horizontal segments, is the core that solves this demand.
The magnetic orientation measuring technique two key components are arranged: magnetic source signal generator and Magnetic Sensor.The magnetic signal that the magnetic source signal generator produces can be detected by the Magnetic Sensor of top well, and the constructor adjusts the position and the well track of drill bit according to the field signal that detects, thereby realizes magnetic orientation.
Summary of the invention
For realizing two horizontal well positioning requirements, the utility model provides a kind of magnetic source signal generator.
A kind of magnetic source signal generator mainly is made up of top connection, power connection, body, coil, insulating rigid rubber, plug seat, plug, lower contact etc.Power connection is housed in the top connection, and power connection links to each other with coil.Coil is wrapped on the body, and the coil turn external surface uses the insulating rigid rubber seal, have in the coil alternating source by the time produce magnetic field.Plug is enclosed within on the plug seat, and plug is an one-way tape wing plug.Lower contact is threaded on the plug seat, and plug is fixed.
The utility model major advantage is: pressurize by waterpower and realize being lowered to of signal source, can avoid the operation of oil pipe punching; The insulating rigid rubber seal is good, can effectively protect coil; Field operation is simple.
Description of drawings
Fig. 1 the utility model structural representation
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described in further details.
A kind of as shown in Figure 1 magnetic source signal generator mainly is made up of top connection (1), power connection (2), body (3), coil (4), insulating rigid rubber (5), plug seat (6), plug (7), lower contact (8) etc.Power connection (2) is housed in the top connection (1), and power connection (2) links to each other with coil (4).Coil (4) is wrapped on the body (3), and coil (4) circle external surface uses insulating rigid rubber (5) sealing, have in the coil (4) alternating source by the time produce magnetic field.Plug (7) is enclosed within on the plug seat (6), and plug (7) is an one-way tape wing plug.Lower contact (8) is threaded on the plug seat (6), and plug (7) is fixing.
When the utility model uses: two horizontal well operations, after finishing, the lower part borehole construction is lowered to oil pipe, external cable is connected on the power connection (2), the magnetic source signal generator is put in the oil pipe, by pumping liquid in oil pipe, waterpower is applied on the plug (7), promotes magnetic source signal generator moving in following horizontal well well, arrive the needed assigned address of technician.When last horizontal well well was crept into, the magnetic field of magnetic source signal generator was detected by the Magnetic Sensor in the well of top, and the constructor adjusts the position and the well track of current drill bit according to the field signal that detects, thereby reached the purpose of two horizontal wells location.
