三个创新助推川渝地区天然气开发业务快速发展

中国石油西南油气田公司重组改制成立10年来，天然气开发呈现跨越式发展，产量增长近一倍，2004年产量过100×10⁸ m³，2006年油气当量突破一千万吨，四川油气田成为国内首个以天然气生产为主的千万吨级大油气田。所取得的发展成果与始终坚持“三个创新”是分不开的。①思想创新，不断拓展开发新领域：创新开发思路，上三叠统须家河组低渗透气藏实现规模效益开发；创新开发建设模式，高含硫气田安全清洁开发有序推进；立体开发与滚动勘探开发相结合，老气田开发新领域见到实效。②科技创新，集成发展了五大技术系列：提高气田采收率配套技术、低渗透气藏规模效益开发配套技术、高含硫气田安全清洁开发配套技术、钻井提速工程配套技术、地面建设工程配套技术。③管理创新，优化资源配置：勘探开发一体化，加快了开发建设步伐；精细管理挖潜，老气田实现持续稳产；统筹规划，加快建设，生产系统保障能力大幅提升；深化作业机制改革，提高气田开发效益；产运销一体化管理保障供气，切实履行了政治、经济、社会“三大责任”。

Knowledge and experience from the rapid progress in natural gas development in Sichuan and Chongqing gas fields

Since implementing the reform and reorganization 10 years ago, the PetroChina Southwest Oil and Gasfield Company has stepped into a new era of great-leap-forward development in natural gas discovery and production, and has become the first giant oil and gas company in China who owns a giant gas-dominated field with the productivity of oil and gas over 10 million tons since 2006. The productivity of natural gas in this company increased from 7.5 bcm in 1999 to 14.8 bcm in 2008, with an annual growth rate of 10% in the last decade. An overview of the 10 years of experience shows that the achieved success is attributed to the innovation in three aspects: a. Innovative thinking helps the company to explore more new areas in gas exploration and development. Guided by new exploitation strategies, more industrial shows have been explored from the Xujiahe Formation low-permeability gas reservoirs; by many improved exploitation means, high sour gas fields have been developed in a safe, cost-effective and environmentally friendly way, and more gas has been found from mature gas fields by the way of three-dimensional and progressive exploration and development. b. Innovative technology impels the company to develop its five integrated technical series in the enhancement of gas recovery, the industrial-scale development of low-permeability gas reservoirs, safe, the cost-effective and environmentally friendly development of high sour gas fields, the increase of ROP, and the ground construction. c. Innovative management drives the company to optimize resource distribution. The integrated exploration and exploitation fastens the speed of gas development, fine management stimulates mature gas fields to maintain their steady production, overall planning and fast construction keep the gas production system under smooth operation, the deepened reform and the optimized operation improve the profit of gas field, and the integrated management of gas production, transportation and marketing guarantees gas supply and helps the company to implement its political, social and economic responsibilities.
