摘要
对四川油气田裂缝性、孔隙性、低渗透储层以及高陡构造的落空直井、开采到后期的枯竭油气井等运用定向井工艺技术,增加钻遇裂缝的机遇率、扩大泄油气面积、减少排油气阻力,重新实现其地质目标,进行二次勘探开发,以增加油气储量、产量。针对不同的地质特点,结合多年四川定向井工艺技术的实践认识,分析了各类油气藏的地下、地面条件、对拓宽定向井工艺技术的必要性、可行性和具体实施方案作了阐述,并提出了拓宽定向井技术应用的具体办法和措施。
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.
