Property it is poor the disadvantages of, it is difficult to enter batch production and engineering application, it is unbecoming with the overall technology level of drilling machine so that China's stone
The complete set ratio of oily drilling equipment is low, is not able to satisfy the demand of high-end market in the world, it is difficult to quotient is won in competition in the international market
Machine.It is especially Russian, it is desirable that drilling machine whole supporting drilling tool conveys cat road automatically.
On the other hand, for example middle petrochemical industry of some oil drilling enterprises domestic in recent years, China Petroleum, CNOOC etc. have petroleum
The enterprise of probing ability plays an active part in the bidding of international oil field prospecting business.And international bidding side is protected from safety, duration, labour
Shield etc. considers, it is desirable that tenderer must have drilling rod and convey the construction equipments such as harness automatically, and not as bid qualification
The necessary condition that can or lack, there is a requirement that under, the drilling tool that Chinese Enterprise has to buy expensive foreign conveys hydraulic ramp automatically,
Or overseas equipment is leased with high cost.
