Description
Technical field
The utility model belongs to the oil-gas exploration and development technical field, relates to a kind of separated type pulsed plasma borer system.
Background technology
Along with the fast rise of petroleum resources demand, the advanced drilling equipment of development is the active demand of our oil gas strategy.Traditional boring method has mechanical boring method and chemical substance blasting procedure.The former utilizes mechanical drilling tool that the impact of rock and shear action are realized fragmentation to rock having characteristics simple in structure, easy to operate, but has the easily shortcoming such as wearing and tearing of drilling tool; Thereby the latter chemical substance impacts the fragmentation that realizes rock at the energy that moment reaction discharges to rock, has the advantages such as simple to operate, that detonation velocity is fast, but has simultaneously that broken disturbance is large, poisonous and harmful substance produces and the shortcoming such as pass is irregular.

Wherein,
Be the energy efficiency that obtains in the load, Z is the characteristic impedance of transmission line, and R is the inner characteristic impedance that forms plasma channel after rock punctures.If obtain higher energy efficiency, the characteristic impedance when the desirable characteristic impedance of pulse transmission line will puncture with rock equates.And existing burst transmissions cable (RG215, RG218 etc.), its characteristic impedance is generally 50 ohm even higher, domestic is 10 ohm by Qingdao Haiyang develop for the minimum characteristic impedance of the coaxial water cable of pulsed plasma borer system at present, under the high like this characteristic impedance of transmission line, the load rock is difficult to obtain higher energy efficiency.For this situation, many research institutions have proposed new circuit structure and have solved this resistance matching problem, the people such as J Biela have proposed solid-state switch power supply (J. Biela et al, Solid State Modulator for Plasma Channel Drilling[J], IEEE Transactions on plasma science, 2009:1093-1099), the position sensing that this method is placed actuating coil is difficult to satisfy this requirement in the real work.Professor Yan Keping of Zhejiang University has developed a kind of assembled pulse power supply based on pulse forming network (ZL 2,009 2 0295616.0), and this method can better realize the coupling of impedance, still has problems but solve in the long range pulse transmission.
In addition, increase along with the burst transmissions cable length, the steepness of pulse front edge can be because the meeting that affects of stray inductance or stray capacitance further descends, when the rising front of voltage does not reach requiring of hundred nanoseconds, rig is with regard to cisco unity malfunction, and Here it is that conventional plasma rig can not be realized one of reason of degree of depth drilling well.
