“十二五”以来,中国石化西南油气分公司面对日益复杂的勘探开发对象和扭亏创效的巨大挑战,坚持科技创新,发展完善了陆相碎屑岩和海相碳酸盐岩两项勘探理论,形成了生物礁、河道砂岩和致密砂岩等三类气藏开发配套技术,创新发展了智能滑套分段改造工艺、喷封压一体化储层改造工艺、脉冲压裂技术、超深高含硫水平井钻完井及投产关键技术等工程技术。上述理论创新和技术进步有力支撑了四川盆地川西陆相碎屑岩、川西海相碳酸盐岩、川南海相页岩气、川东北元坝海相碳酸盐岩等领域的重大突破,发现了3个千亿立方米级规模天然气商业储量区,探明了2个、建成了3个大中型气田,天然气储产量创历史新高。“十三五”期间,将重点攻关深层海相碳酸盐岩气藏勘探开发、深层页岩气商业开发、高含硫气田安全开发和开发老区气藏提高采收率技术,到“十三五”末天然气年产量力争达到(100~120)×10~8 m~3。
Since the 12th Five-Year Plan, SINOPEC Southwest Oil & Gas Branch has faced the tremendous challenge of becoming an increasingly complex exploration and development target and turning losses into a success. With its scientific and technological innovation, Sinopec Southwest Oil and Gas Branch has developed and perfected continental clastic rocks and marine carbonate rocks Two exploration theories have formed three types of gas reservoirs supporting technologies such as reefs, channel sandstone and tight sandstone. Innovative development has been made in the areas of intelligent slip-sleeve rebuild process, spray-seal pressure integrated reservoir rebuild process, pulse fracture technology, Ultra deep and high sulfur horizontal well drilling and completion and commissioning of key technologies and other engineering techniques. The above theoretical innovations and technological advances have strongly supported major breakthroughs in continental Sichuan continental continent clastic rocks, western Sichuan marine carbonate rocks, southern Sichuan marine shale gas and Yuanba marine carbonate rocks in the Sichuan Basin. They found that Three commercial scale reserves of 3 billion cubic meters of natural gas have been identified, 2 proved and 3 large and medium-sized gas fields have been built. The output of natural gas has hit a record high. During the “13th Five-Year Plan” period, we will focus on exploration and development of deep-sea marine carbonate gas reservoirs, commercial exploitation of deep shale gas, safe development of high-sulfur gas fields and development of recovery technologies for old gas reservoirs, The output of natural gas at the end of the “Thirteen Five-Year Plan” will strive to reach (100-120) × 10-8 m ~ 3.
