The paper outlines the present state of the art of deep sea drilling and discusses some of the problems with the ‘controlled’ as well as the ‘uncontrolled' techniques. The first method is being developed by the contract drilling companies under the auspices of the oil industry, while the second method was introduced by the Deep Sea Drilling Project under the guidance of a group of oceanic institutions (Joides). The oil industry has drilled controlled in water depths of up to 1000 m and slightly over, and is now capable of extending the technique to 2000 m. Joides contemplates controlled drilling in water depths to 3650 m, say by the end of 1981. It is suggested that not only the slope but also the rise of the continental margin should soon be investigated in a number of suitable localities in order to assess adequately the potential of the last remaining major unexplored frontier for oil and gas. The paper emphasizes that it is already possible today to carry out controlled exploration even to water depths of over 4000 m. If such exploration were successful, production could also be achieved by making use of the presently developing underwater technology in 200-300 m of water.

Exploration And Development

In recent years, China has made certain achievements in shallow sea petroleum geological exploration and development, but the exploration of deep water areas is still in the initial stage, and the water depth in the South China Sea is generally 500 to 2000 meters, which is a deep water operation area. Although China has made some progress in the field of deep-water development of petroleum technology research, but compared with the international advanced countries in marine science and technology, there is a large gap, in the international competition is at a disadvantage, marine research technology and equipment is relatively backward, deep-sea resources exploration and development capacity is insufficient, high-end technology to foreign dependence. In order to better develop China's deep-sea oil and gas resources, it is necessary to strengthen the development of drilling and completion technology in the oil industry drilling engineering. This paper briefly describes the research overview, technical difficulties, design principles and main contents of the completion technology in deepwater drilling and completion engineering. It is expected to have some significance for the development of deepwater oil and gas fields in China.

“CPOE62”platform is a self-elevating workover platform. Under the construction and service process，because of the particularity of work environment，Not only does it bear its own weight and variable load, but also bears the role of environmental load all the time. Sometimes this environment load will have an enormous destruction. Based on the analysis of environmental load, the author checks the bottom stability and verifies it through ANSYS. These will provide some useful information for the deep sea platform research in Bohai Sea deep-water oil and gas development, which achieves higher security and economic efficiency.

In preparation for the near future deep-water exploitation in the Mexican oil industry, the Mexican Petroleum Institute and Pemex carried out the first oceanographic sub-surface mooring installation in deep waters, in Lankahuasa area in 1500 m water depth. The aim of this project is to supply the necessary water column information for planning, installation, development and production activities for the Mexican offshore industry. Parameters measured include, current velocities, current direction, internal waves as well as traditional water quality measurements. Profiles of conductivity, temperature and Depth (CTD) from 100 m up to 2,500 m water depths were obtained from cruises where samples were taken over a wide area during January and February 2005. Salinity and density are calculated from CTD data. Oceanographical parameters were measured by 3 ADCP (Acoustic Doppler Current Profile) and by 2 current meters in the entire water column. The oceanographic situation during the deployment was characterized by the presence of an anticyclonic (clockwise rotating) eddy and a cyclonic one in the area, located to the north of 21° N. Both eddies were slowly propagating in a general southward direction.

Theoretical Results

The article presents an analysis of the realities faced by the operators in the oil industry, but especially the operators in the exploitation of the risers. Oil industry operators are focusing on drilling offshore wells to very deep water depths, as there are significant oil and gas resources that ensure high production. This analysis refers to the establishment of limit conditions that occur during drilling operations. We call this complex of factors the mechanics of riser. The article also refers to establishing the way of working in accordance with the API recommendations in force and obtaining theoretical results for offshore drilling in deep water. *Автор для переписки. E-mail: [email protected] 94 НЕФТЬ И ГАЗ 2020. 3–4 (117–118) БУРЕНИЕ These results are the starting point for simulation with the help of specialized software and obtaining results useful for the exploitation of risers in drilling wells in deep water. Drilling activity in deep water can only be done with dynamically positioned platforms, such as semisubmersibles platforms and drillship.
