Description
Technical field
The present invention relates to technical field of geophysical exploration, the group of more particularly to a kind of mud gun epicenter drilling tool and mud gun epicenter
Close exciting method.
Background technology
Current land oil exploration mainly uses controlled source and well big gun explosive as excitaton source.It is more than 3m (rice) in the depth of water
Waters use air gun source as excitaton source, and the 0-1.5 meters of land and water of the depth of water alternatively band and swampy area, due to controllable
Focus and air gun ship cannot be travelled and passed through, and can only use explosive.Corresponding rig, fortune are accomplished by as excitaton source using explosive
The equipment such as defeated, not only construction cost is higher, and there is a problem in that：The feature of environmental protection is poor, potential safety hazard is more.Additionally, one
A little areas do not allow to use explosive, cause in these areas without suitable excitaton source.
At present, relatively advanced explosive source is mud rifle with brill explosive source.Mud rifle is a type of air cannon, its base
This structure is a cylinder block for the stainless steel material with certain capacity, and gases at high pressure are filled with to it by air compressor system
And pressure is kept, the gun body that will be filled with pressure-air is put into water or in mud, by the control of magnetic valve, makes the high pressure in cylinder
Air abrupt release, produces the shock pulse of some strength as earthquake stimulation focus.That is, mud rifle is used as explosive source
Shi Tongchang is placed in mud rifle in drilling tool, using spiral drilling technology by mud rifle sinking to deeper depth.Above-mentioned mud rifle is with brill
It is wider that comparatively explosive source adapts to stratum, mainly rifles battle array is formed using horizontal layout multiple shot points when it is used, to carry
Mud rifle energy high, meets oil exploration.But it is on the whole, this to arrange that multiple shot points form rifle battle array and excited in the plane
Method a shot point need bore multiple wells, take it is more long, thus with bore launching efficiency it is relatively low.
In sum, it is necessary to the combined method of a kind of efficient mud gun epicenter drilling tool and mud gun epicenter is proposed, to overcome
Deficiency of the prior art, especially for the 0-1.5 meters of land and water of the depth of water, alternatively band and swampy area provide swashing for high efficient and reliable
