The specific embodiment
As shown in Figure 1, paper is unconventional oppositely to the method for wearing, and comprises the following steps:
Step 1: be provided for the well site 3 of drilling straight-hole 2 above the end of horizontal well 1, upper rig;
Step 2: when this straight well 2 is drilled into apart from this horizontal well 100m, this straight well 2 stops creeping into;
Step 3: by rotating signal omniselector 5 with deliver to the target location of this horizontal well 1 end for receiving the inserting tube 4 of magnetic signal, also can be called target position with the drilling rod of workover rig;
Step 4: the bottom to this straight well 2 is lowered to for launching the strong magnetic short section 6 of magnetic signal, inserting tube 4 can receive the magnetic signal that strong magnetic short section 6 sends and this signal is sent to control module, unconventional in this control module oppositely constantly revised target spot data to wearing the characteristic signal that software can receive according to inserting tube 4, guide this straight well 2 to the drilling trace of this horizontal well 1 end target location, thereby successfully realize and unconventionally oppositely to wearing, provide data accurately and reliably for it;
Step 5: for fear of the MGS inserting tube in horizontal well 1 impaired when very near to wearing distance, when straight well 2 is drilled into apart from horizontal well 10m, straight well 2 stops creeping into, from horizontal well 1, trip out inserting tube 4, and then make straight well 2 according to oppositely the target spot data that provide are provided are continued to creep into horizontal well 1 wearing software, until straight well 2 with horizontal well 1 successfully to wearing, straight well 2 carries out completion practice again.
Because be producing well before horizontal well (old well), well has been lowered to screen casing (ferromagnetic material), and the magnetic signal of strong magnetic short section 6 transmittings of working in straight well 2 is had to shielding action, can produce magnetic disturbance simultaneously.So inserting tube 4 is arranged on as shown in Figures 2 and 3 in rotating signal omniselector 5, with anti-interference, reduce signal attenuation simultaneously, this rotating signal omniselector 5 is made for nonmagnetic substance.Inserting tube 4 is MGS(Magnetic Geosteering System) inserting tube, this inserting tube 4 is commercially available.MGS inserting tube is arranged in rotating signal omniselector 5, drilling rod 7 and rotating signal omniselector 5 are coupled together, the mode of taking cable punching to carry is transported to target position (to wearing position) with drilling rod by MGS inserting tube.
Concrete, described rotating signal omniselector 5 comprises the housing 51 of tubular, in the right-hand member of housing 51, there is installation cavity 53, in installation cavity 53, be provided with for the fixing instrument fixator of inserting tube 4, the structure of this instrument fixator as shown in Figure 4, the inwall fixed seal connection of this instrument fixator and housing 51, as Fig. 2, shown in Fig. 3 and Fig. 4, the left end of this rotating signal omniselector 5 is fixedly connected with drilling rod 7, inserting tube 4 is arranged in rotating signal omniselector 5, what inserting tube 4 was similar match is shaft-like, inserting tube 4 comprises head and bar portion, sensor is mainly arranged in the head of inserting tube 4, the bar portion of inserting tube 4 is plugged in the instrument fixator of rotating signal omniselector 5, as shown in Figure 3.
Between the two ends of housing 51, be provided with a plurality of strip through-holes 52.Strip through-hole 52 is along the axial setting of housing 51, and the length direction of strip through-hole 52 is along the left and right directions in Fig. 2.The length of strip through-hole 52 is 1000mm～1500mm.The wide of strip through-hole 52 is 15mm～20mm, when the bar portion of inserting tube 4 is plugged in the instrument fixator of rotating signal omniselector 5, the position of the head of inserting tube 4 with the position of through hole 52 to corresponding.Strip through-hole 52 is set like this and not only can makes housing 51 for inserting tube 4 provides electromagnetic shielding, can also make the foreign material such as silt in this rotating signal omniselector 5 discharge from this through hole 52.
As shown in Figure 3 and Figure 4, this instrument fixator comprises columniform retainer bottom 56, the inwall fixed seal connection of retainer bottom 56 and housing 51.One end of retainer bottom 56 is provided with centralizer 55, and centralizer 55 is arranged in housing 51, and centralizer 55 is connected and fixed by key.Centralizer 55 is connected with columniform retainer top 54, and the inwall fixed seal connection of retainer top 54 and housing 51 is provided with the through hole of pegging graft for inserting tube 4 in retainer top 54.The other end of retainer bottom 56 is provided with columniform fixator afterbody 57.This instrument fixator comprises retainer top 54, centralizer 55, retainer bottom 56 and the fixator afterbody 57 connecting successively, as shown in Figure 4.
