Background
The oil and gas burial depth of a Tarim basin carbonate reservoir is 5500-7000m, especially the burial depth of a depression region in northern part of Tarim is 7000-8500m, and partial region is close to 9000m, so that the geological condition is complex and the drilling difficulty is high. During the drilling process, along with the increase of the drilling depth from top to bottom, the hardness of stratum rock is increased, the mechanical drilling rate is obviously reduced, and the drilling period and the construction cost are increased. After 2000, the bit rate is improved by trying to match the PDC bit with various underground speed-up tools and the like, but the mechanical bit rate improvement is not broken through. Especially, under the condition of a rotary drilling process, the PDC drill bit can not continuously contact with the bottom of a well to maintain balance due to the fact that the PDC drill bit bears unstable torque to generate disordered motions such as transverse motion, longitudinal motion, torsional motion and the like, so that the damage service life of the cutting teeth is shortened, and the mechanical drilling speed is influenced. At present, hydraulic impactors at home and abroad have various models, but five main types exist: positive hydraulic impactor, reverse hydraulic impactor, valve type double-acting hydraulic impactor, jet type hydraulic impactor and jet-suction type hydraulic impactor. Although the problem of drill bit disordered motion is reduced or even eliminated to a certain extent by the existing impactors, the impact frequency and impact load generated by the impactors are limited by various factors such as the structure of the impactors and the performance of drilling fluid, the adjustment difficulty is high, and further the adaptability to PDC drill bits is poor and the pertinence is not strong, so that the application range of the PDC drill bits is limited.
In the prior art, chinese patent No. CN92223645.3, "electromagnetic force impact rotation device", proposes an electromagnetic force impact rotation device, which is characterized in that the device has two independent magnetic circuit systems, and a special power supply device supplies power to the two independent magnetic circuit systems in turn according to time sequence, so that the electromagnetic force directly drives an impactor of a machine tool, and the impactor generates repeated impact motion and can rotate, thereby realizing the breaking of hard rocks and concrete, and achieving the purpose of continuous hole drilling. The energy utilization rate is high, the energy-saving effect is particularly obvious, and the impact force of the impactor is large. The working frequency can be adjusted by a special power supply. The device is light, simple and firm in structure, easy to move, low in cost, less in maintenance work and the like. The tool is only suitable for ground or mining and the like, and is not suitable for drilling operation of petroleum ultra-deep wells. Chinese patent "an electromagnetic spring impacter" with patent number CN201611082362.5, an electromagnetic force impact rotary device is proposed, the polarity after the circular telegram of electromagnetic block is the same about adopting, utilize the principle that like poles repel each other to upwards compress the spring and do work, the hammer strikes the anvil block under the effect of spring after the outage, the brill body keeps the constant rotational speed rotatory under the main shaft effect simultaneously, make the brill body have certain percussion power at rotatory in-process, such broken rock, the effect of breaking ground is better, strike always at the bottom of the hole simultaneously, power can not be exhausted, high work efficiency, better popularization and application prospect has. Obviously, the tool is not suitable for drilling operation of deep wells and ultra-deep wells of oil and gas wells.
For the ultra-deep well drilling of the Tarim basin, the key for improving the mechanical drilling speed is to reduce or eliminate the damage of disordered movements such as transverse, longitudinal and torsional movements to cutting teeth aiming at a specific stratum, and provide a long-term and stable working condition for the PDC drill bit. However, although the problem of drill bit disordered movement is reduced or even eliminated to a certain extent by the existing equipment, the generated impact frequency and impact load are limited by various factors such as the structure of the impactor, the discharge capacity and the performance of drilling fluid, the adjustment difficulty is high, and further the adaptability to the PDC drill bit is poor, the pertinence is not strong, and the application range of the PDC drill bit is limited.
Therefore, how to provide an impactor tool suitable for drilling the ultra-deep well PDC to assist in rock breaking can reduce or even eliminate the problem of disordered movement of the drill bit, and meanwhile, the impactor tool has the characteristics of simple structure, reliable working performance and wide application range, improves the mechanical drilling speed of the PDC drill bit in the deep well and the ultra-deep well, and becomes a technical problem which needs to be solved urgently by technical personnel in the field.
