1. Description
In the drilling process, the drill bit is the main tool to break the rock and the wellbore is formed by the drill bit breaking the rock. How well a wellbore is formed and the length of time it takes are not only related to the characteristics of the rock in the drilled formation and the performance of the drill bit itself, but also to the degree of mutual matching between the drill bit and the formation. Reasonable selection of drill bits plays an important role in increasing the drilling speed and reducing the overall cost of drilling.
The drill bit is one of the important tools for oil drilling work. Whether the drill bit adapts to the rock properties and its quality plays a very important role in the selection of drilling technology, especially in terms of drilling quality, drilling speed and drilling cost.
2. Specifications we can offer
At present, there are many types of drill bits used in the petroleum industry and mining industry. The drill bits are classified according to different drilling methods. They can be divided into PDC drill bits, roller cone bits, scraper bits and mining diamond coring bits. These drill bits are the most basic drill bits and we all can provide.
Perfecting the fire rescue network of the city village, the mini fire engine is indispensable
The miniature fire truck not only has strong maneuverability, but also has great advantages when facing complex roads such as community towns and towns. Its smart body can quickly reach the scene of the fire and timely carry out fire rescue work. As an indispensable part of urban development, community transformation and upgrading, enterprise fire management and intensive workplace safety and security, the role of miniature fire engines is becoming more and more obvious, and it is receiving more and more attention. The water mist fire extinguishing system is not only green and environmentally friendly, but its fire extinguishing efficiency is several times that of traditional fire engines. It has great advantages in dealing with complex fire sources in communities and factories, effectively solving high-level fire rescue, fire fighting and flooding and secondary pollution. The problem.
In many people's minds, fire trucks only need to work hard on fire fighting work. In fact, the fire fighting capacity of fire trucks is unquestionable, but if its speed does not reach a certain level, fires occur in some areas. It will also affect the rescue work. With the miniature fire truck, even if the fire brigade is far away, once the alarm is received, the miniature fire truck can save the people in distress by virtue of its speed advantage. Therefore, in recent years, developers have made great efforts on the speed of micro-fire trucks, such as reducing some of the heavier equipment in the car and replacing it with lightweight equipment. Other fire trucks will replace high-powered engines and increase the specific power to achieve faster speeds. It is worth noting that the fire truck itself has certain specialities. Because it needs to be extinguished, it is impossible to increase the speed by sacrificing the fire extinguishing equipment.
Nowadays, in all parts of the country, in the case of limited police force in various places, the advantages of micro-fire trucks can be further developed. Based on the power of group defense, a community mini-fire station will be set up. After professional training by fire officers and soldiers, they will be combined with traditional fire engines. Combined, a fire network with "a little alarm, multi-point linkage" is formed. For example, last month, a fire broke out in Jinhua, Zhejiang Province. A private house caused a fire due to electrical failure. However, when firefighters went to the rescue, they It is full of private cars. It is understood that the area belongs to the urban village. Due to the road reconstruction, the fire-fighting houses were transformed into fire-fighting passages after some buildings were demolished. The area was stopped during the fire that night. The owner was informed that the car was removed and the fire truck was able to get close to the fire house.
In response to this phenomenon, Jinhua Firefighting has adapted local conditions and promoted the construction of micro-fire stations in different steps and sub-regions. Up to now, Jinhua City (except Yiwu) has built 256 community mini-fire stations and 828 key fire stations. The micro-fire station can make full use of human resources and fire-fighting equipment in daily fire prevention. It can discover and control the fire in the jurisdiction within a short period of time, and effectively achieve the goal of “rescue early, small and 3 minutes to arriveâ€. As an important part of the miniature fire station, the miniature fire truck plays a certain role in the initial fire fighting and rescue, killing the fire in the bud, and through the system modification and integration, it has the advantages of quick response, flexible action, etc. It can take advantage of the flexibility of the body to enter the street, and the first time to rush to the scene for initial rescue and fight for more fire-fighting time.
