今年以来,中原油田采油二厂按照“成熟技术规模推广,核心技术加大攻关”的工作思路,联合攻关以压裂、酸化为主的低渗透油藏效益开发关键技术,取得良好成效。截至目前,累计开展以储层改造、老井侧钻、常关井修复为主的各类技术攻关650余井次,单井日增油比去年多1.3吨,目前已累计增油44915.8吨。 Since the beginning of this year, Zhongyuan Oilfield Production Plant No. 2 has achieved good results by jointly developing the key technologies of fracturing and acidizing low-permeability reservoirs in accordance with the principle of “popularizing mature technologies and increasing core technologies”. Up to now, a total of more than 650 wells of various kinds have been developed, mainly reservoirs retrofitting, sidetracking of old wells and repairing wells that are normally closed. The daily oil production of single well is 1.3 tons more than that of last year, and 44,915.8 tons of oil have been accumulated.
