Description
Technical field
The present invention relates to a kind of fluid power pulse generating unit and its method of operating, belong to the brill of oil and gas exploitation industry
Well field of engineering technology.
Background technology
Petroleum resources in stratum is based on certain drilling technique, forms well in the earth formation by well system and opens
Extraction comes, and the system includes ground system and underground equipment etc..Wherein drill string is one of most important underground equipment, and it both made
For transmitting the barrier of annular space drilling fluid inside and outside the bridge of well head power, and isolation.As what petroleum resources was exploited constantly enters
OK, drillng operation is constantly shifted to deep formation, and the quantity of deep ＆ ultra-deep well is incrementally increased.Distribution according to China's petroleum resources
Feature, has 52% to bury in deep formation, the petroleum resources in west area in the natural gas in the sweet peaceful two big basin in Sichuan and Shan
This ratio reaches 73%.At the same time, the oil and gas development of China is also progressively strided forward to deep-sea.
Under normal circumstances, with the increase of well depth, rock strength increases and drillability is deteriorated, and thereby results in rate of penetration relatively low
And drilling tool easily fails.In-situ data shows that the average rate of penetration of unit of China dam area deep-well drilling is only that its top well section is put down
The 15%-30% of equal rate of penetration, some areas ratio are even below 8%.For the low problem of deep formation drilling efficiency,
International drilling well business contracts association (IADC) and repeatedly holds the seminar with regard to improving deep plot drilling efficiency.Existing with regard to improve
The method of rate of penetration has multiple, for example, improve drill bit, improve BHA, optimize drilling technology etc..However, through for many years
Development, these methods are all more ripe, and the raising to rate of penetration is also limited.
In recent years, impact or pulse are used for drilling well so as to improve rate of penetration very generally, such as axial impact
Hydraulic impacter, the pneumatic hammer of gas drilling, the reverse impactor of torsional pulse, other instruments also include hydroscillator etc.
Instrument.Although the existing method with regard to drilling speed have multiple, in-situ data show these technology cannot universality should
With Some tools are even as physical dimension has considerable influence to lower drilling tool.Drilling fluid is to be used for cooling down in drilling process
How drill bit and the indispensable medium of cutting carring, therefore make which while realizing not only functional using this medium but also make which can
It is that difficult point is located to improve rate of penetration.Due to the drilling fluid at drill bit directly and rock contact, so if on drill bit
Side arranges an instrument for being used for producing pressure and flow-rate impulse, can improve the mechanical characteristic of rock and accelerate rock unit to damage
Wound, so as to further improve rate of penetration, present disclosure is how to design such a device.
