张家场气田,是被中国石油天然气总公司命名的、全国三个“高效气田”之一。第5号井,是该气田石炭系气藏的一口主力产气井,从1983年3月投产以来,井组人员坚持从井下实际出发,加强科学管理,及时向专业队伍提供准确资料,进行了两次卓有成效的井下作业、使本井一直保持稳产,到1991年8月,已累计采气3.53×10~8m~3,占该气田C_2气藏已采出气量的17.7％,目前日产天然气仍保持在9～10×10~4m~2。这口井的管理特点,可从纵向上分为出水前与出
Zhangjiachang gas field, is named by China National Petroleum Corporation, the country’s three “efficient gas field” one. Well No.5 is the main gas production well of the Carboniferous gas reservoirs in this gas field. Since it was put into operation in March 1983, well group personnel have insisted on proceeding from the actual conditions in the well, strengthening scientific management and providing accurate information to professional teams in time. The effective underground operation has kept this well stable. By August 1991, it had accumulatively collected 3.53 × 10 ~ 8m ~ 3 of gas, accounting for 17.7% of the recovered gas in the C_2 gas field of this gas field. At present, the natural gas of Nissan remains In 9 ~ 10 × 10 ~ 4m ~ 2. The management of this well can be divided vertically into effluent before and after
