China Petroleum Network News (reporter Liang Wei) on October 15, the reporter learned that the drilling depth of Shuangyu 001-x3 well in southwest oil and gas field undertaken by Chuanqing Drilling company Chuanxi drilling company was 8600m deep, setting a new record for the deepest completion depth of onshore horizontal wells in China. Beishi dq90bsc integrated top drive, which is used to complete the drilling task of the well, plays a key role.
Well Shuangyu 001-x3 has many drilling problems, such as ultra deep, ultra-high pressure, ultra-high temperature, high sulfur content, narrow density window, difficult hole trajectory control and complex longitudinal pressure system. Beishiding drive is designed in accordance with the principle of unified form, unified supporting and unified interface. The integrated electric control mode is adopted to reduce the equipment transportation unit. Under the collaborative application of the field information identification system, the integrated control informatization degree can be effectively improved.
At the same time, the supporting string automatic processing equipment and auxiliary tools of Beishi top drive have realized the whole process of automatic transportation, screwing and pipe laying, greatly improving the mechanization degree of well site operation.
Since 2018, nearly 60 sets of beishiding drive have been widely applied in the major drilling companies of CNPC according to the overall development plan of CNPC automatic drilling rigs, which has effectively promoted the oil and gas exploration and development of key blocks, effectively promoted the “four modernizations” construction of engineering and technical service team, and accelerated the realization of the “five provinces” target of oilfield operation site.
