吴堡作业区开采南梁西区块,位于甘肃省华池县纸坊乡至陕西省志丹县义正乡内,区域构造位于鄂尔多斯盆地南部沉积中心,为陕北斜坡南部——西倾单斜区域。主要含油层系为延长组长9、长8、长7、长6、长4+5、长3油层组和侏罗系。近3年来,受厂家光杆质量问题等影响,吴堡作业区光杆断1 6 5井次,占总维护作业井次的8.7%,油井光杆断后易造成井口喷油,造成井场污染,存在较大的安全隐患。2015-2016年吴堡作业区在油井井口试验安装自动防喷盘根盒,在光杆断入井口后,内置回弹装置将密封件弹出,立即自动封住井口。
Located in Yizheng Township, Zhifang County, Shaanxi Province, Zhifang Township, Huachi County, Gansu Province, the Wubao operation area is located in the sedimentary center of the southern Ordos Basin and is the southern part of the northern Shaanxi slope . The main oil-bearing strata are the extension group 9, the long 8, the long 7, the long 6, the long 4 + 5, the long 3 reservoir and the Jurassic. In the recent 3 years, affected by the polished rod quality problems of manufacturers, there were 165 wells in Wubao operation area, accounting for 8.7% of the total maintenance operation. After the shutdown of the oil well light rod, it was easy to cause oil injection at the wellhead, resulting in the contamination of the wellsite. Big security risk. 2015-2016 Wubao work area In the wellhead test installation of automatic anti-pucker root box, polished rod in the wellhead, the built-in rebound device will pop-up seals, immediately automatically seal the wellhead.
