The whole process of Petroleum Exploration and Development – Drilling

After the oil workers will find the oil storage area through exploration, the use of special equipment and technology, in the pre-selected surface position, down or a side of the cylindrical hole of a certain diameter, and drill to reach the underground oil and gas layer work, called drilling.

Drilling plays a very important role in the tasks of petroleum exploration and oilfield development.Such as finding and verifying oil-bearing structures, obtaining industrial oil flow, verifying the oil-bearing area and reserves of proven oil-bearing structures, obtaining geological and development data of related oil fields, and finally bringing crude oil from underground to the surface, etc., are all accomplished through drilling.Drilling is an important link of exploration and exploitation of oil and natural gas resources, and an important means of exploration and exploitation of oil.

The petroleum exploration and development process is made up of many stages with different natures and different tasks.In different stages, the purpose and mission of drilling will vary.Some are for the exploration of oil storage structures, and some are for the development of oil fields and the extraction of crude oil.In order to adapt to the needs of different stages, different tasks.

The types of drilling can be classified as follows.

1) Reference well 2) Profile well 3) Parameter well 4) structural well 5) exploration well 6) data well 7) Production well 8) Water injection well 9) Inspection well 10) Observation well 11) Adjustment well
