DEVELOPING THE APPLICATION OF DIRECTIONAL WELL TECHNOLOGY

Shi Zhonghua(Drilling Department of Sichuan Petroleum Administration),Wang Junliang:  
Applying directional well technology to the porous reservoirs with fractutes and low permeability,the drop out straight wells on the high steep structure and the oil gas depleted wells,oil gas reserves and production can be enhanced by secondary exploration and development for increasing the oportunity of drilling through fractures,expanding oil gas leakagearea,reducing oil gas exhaust resistonce.According to the geological characteristics and surface and underground conditions of various gas reservoirs in Sichuan gas fields,the necessity,feasibitily and practicable plans of developing directional well technology are expounded.
