摘要

In China, at least 50percent of the total oil and gas resources exist in the low permeability resrevoirs. Whether the low permeability oil and gas resources can be produced and utilized commerically is one of the important problems for China's energy supplying in the 21st century. The most important problem in the exploration and exploitation of low permeability oi8l gas resources is the serious formation damage in pay zones. This formation damage exists from the beginning to the end in drilling, well completion, simulation, oil and gas production. Another important problem is the economical benefit. The production and utilization of low permeability oil and gas resources was limited by the high input and the low output. Based on systematical analysis of reservoir characters, damage mechanism and flowing patterns of low permeability reservoirs, a suit of techniques was worked out to deal with low permeability reservoirs in this paper, including exploration, reservoir description, drilling, well pattern, stimulation and production.
