辽河油田欧52井火山岩油层三元酸压裂酸化工艺技术

Fracturing Acidizing Technology of Well Ou#52 in Ternary Acid Volcanic Reservoirs of Liaohe Oilfield

辽河油田东部凹陷火山岩油藏较为集中分布．然而常规酸化效果较差．经采用三元酸（粉末硝酸、盐酸和氢氟酸）前置液压裂酸化后．获得显著的增产效果，进一步表明该项酸化工艺技术成熟，宜于推广应用。同时也面临技术集成再创新机遇．适应更广泛的地质需求。

Liaohe Oilfield eastern Depression volcanic reservoirs more focused distribution, but less effective conventional acidification by using ternary acid （powder nitric acid, hydrochloric acid and hydrofluoric acid） after acidification front hydraulic splitting, access to significant yield effects, and further indicates that the acidification of mature technology, the supply application. Technology Integration at the same time is also facing a new opportunity and adapt to a wider geological demand.
