摘要:
普光气田单井储层物性差异大,Ⅰ、Ⅱ、Ⅲ类层交互发育,非均质性较强,平面展布变化大,气井投产采用酸压、生产一体化永久式管柱。针对个别井投产后出现生产压差较大,产剖测试储层动用程度低的问题,在不动管柱条件下,研发了高抗硫小直径旋转喷枪,采用连续油管拖动酸化,可实现任意层段喷射,通过酸液溶蚀、压力挤入、冲击波扰动三重效果改善产气剖面。该技术在P101-3井成功应用。
Abstract:
In Puguang Gasfield,the physical properties of single well reservoirs are quite different. Type I,II,and III layers are alternately developed,with strong heterogeneity,and large changes in plane distribution.Gas wells are put into production using acid fracturing and production integrated permanent pipe strings. In view of the problems of large production pressure difference after the production of individual wells and low production rate from the production profile test,the high-sulfur-resistant rotary spray gun with small diameter was developed under the condition of the fixed pipe string,and the coiled tubing was used to drive acidification.which can realize spraying at any interval,and improve the gas production profile through the triple effects of acid dissolution,pressure squeezing,and shock wave disturbance.This technology was successfully applied in P101-3 well.
