The first-stage construction in the zone will cover an area of 2.2 sq kms. The zone is 40 kms away from Beijing, 60 km from Tianjin, 105 kms from Tianjin New Harbour, and only six kms from Langfang Railway Station. Telecommmunications facilities in the zone are connected with a 10, 000-line programme-controlled telephone switchboard imported by the city from Canada, 500-line long-distance automatic telephone equipment, and展开更多

There are many places where oil is used in people's lives, such as cars and other means of transportation. Oil not only plays an important role in people's way of life and travel, but also plays an important role in many other aspects. Therefore, in order to ensure that people's daily life can be carried out in a normal and orderly way, it is necessary to develop the oilfield geology. Only in this way can more oil be mined to ensure people's daily needs. However, in the actual process of oil exploitation, it is difficult to guarantee people's demand simply by manpower. Therefore, in the process of exploiting the oilfield geology, the corresponding development technology should be used to exploit the oilfield, which will effectively improve the efficiency of oilfield exploitation. However, at present, there are still many problems in using oilfield geological development technology, such as the difficulty of exploitation, the benefit of exploitation, the equipment used in oil exploitation, and so on, which will affect the use of oilfield address development technology. Therefore, in order to exploit the oilfield geology smoothly, it is necessary for the relevant enterprises and managers to conduct a comprehensive investigation and understanding of the oilfield geology before exploiting the oil, and to find professional exploiters to design corresponding and perfect countermeasures for the exploitation of the oilfield geology. This can not only ensure the smooth geological exploitation process of the oilfield, but also ensure the economic benefits of related oilfield enterprises. Therefore, the following content is to analyze and study the technical characteristics and development countermeasures of oilfield geological development.展开更多
