软弱地基处理技术在川西油气钻井开发中的应用

The Application of the Soft Foundation Treatment Technology in the Oil and Gas Drilling and Development in Western Sichuan Areas

油气田钻井开发中钻前工程有其自身的特点,油气钻井中的钻前工程是钻井工艺和建筑工程相结合的复合型工程,由于工程自身的特殊性,除要遵循建筑行业规范和管理程序外,还必须执行石油行业技术规程。根据不同的软弱天然地基和钻机类型制订一套合理的软弱地基处理方案对钻前工程的降本增效有着重大意义。

The predrilling operation has its own characteristics in the oil and gas drilling and development.It's a complex engineering calls for the combination of drilling technology and construction engineering.Due to the particularity of the project,engineers not only should follow the construction industry standards and the management procedures,but also execute technical regulations on the oil industry.According to the different natural soft foundation and the drill type,authors develop a reasonable soft foundation treatment scheme which has great significance for the request of lower cost-higher profit in the predrilling operations.
