去年10月12日,中国石油在川最深气井—双探3井栖霞组储层改造后,测获日产天然气41.86万立方米,这是西南油气田公司在超深、高温、含硫碳酸盐岩储层改造取得的一项重要成果。储层改造是指采用酸化压裂、加砂压裂和体积压裂等工艺措施,疏通或增加油气从地层流入井筒的通道。“十二五”以来,公司在储层改造方面形成了10项特色技术,总体技术水平国内领先。四川盆地碳酸盐岩储层高温、高压、非均质性强,公司形成了高温深井酸化压
On October 12 last year, PetroChina captured 418,600 cubic meters of natural gas after the reconstruction of Qixia Formation, the deepest well in Sichuan - the Shuangntang 3 well. This is a result of the exploration by Southwest Oil and Gas Field Company of ultra-deep, high-temperature, sulfur-bearing carbonate rocks An important achievement of reservoir reconstruction. Reservoir modification is the use of acid fracturing, sand fracturing and volumetric fracturing and other technical measures to clear or increase oil and gas flow from the formation into the wellbore. Since the 12th Five-Year Plan, the company has formed 10 distinctive technologies in the area of reservoir reconstruction, leading the overall technological level in China. Carbonate reservoirs in Sichuan Basin are characterized by high temperature, high pressure and high heterogeneity. The Company formed a high-temperature deep well acidizing pressure
