我所从四川油气田生产实际出发,于1977年7月,研制成功了850大气压平行式闸板闸阀(以下简称平板阀)。在中间试验和现场工业性试验中,证明性能良好,达到了设计要求,能满足高压压裂酸化工艺的需要。该阀研制和试验的成功,为石油工业高压井下作业提供了可靠的井口控制装置。
Based on actual production in Sichuan oil and gas field, in July 1977, we successfully developed the 850-bar parallel gate valve (hereinafter referred to as the plate valve). In the intermediate test and on-site industrial test, it proves that the performance is good, meets the design requirements and can meet the needs of high-pressure fracturing and acidizing process. The success of the valve development and testing has provided a reliable well head control device for high pressure downhole operations in the oil industry.
