2138 amamitha ngosuku olunye! Irekhodi elisha lenziwe
Umthunywa waziswa ngokusemthethweni yi-CNOOC ngomhla ka-31 kuNcwaba, ukuthi i-CNOOC iqedile kahle ukuhlola ukusebenza kokubhoboza emathafeni atholakala elwandle iNingizimu yeChina eduze kweHainan Island. Ngomhla ka-20 kuNcwaba, ubude bokubhoboza bansuku zonke bufike ku-2138 amamitha, kudala rekord entsha yosuku olulodwa lokubhoboza izimbobo ze-oyili nezemvelo. Lokhu kukhombisa ukuphumelela okusha ekusheshiseni ubuchwepheshe bokubhoboza bezimbobo ze-oyili nezemvelo eChina.
Since the beginning of this year, it is the first time that the daily drilling length of drilling on offshore platform has surpassed the mile-stone of 2,000-meters, and the drilling records have been refreshed twice within one month in the sector of Hainan Yinggehai Basin. The gas well that showed the drilling record-breaking was designed to be over 3,600 meters in deep, with a maximum bottomhole temperature of 162 degrees Celsius, and it was required to drill through multiple stratums of formations of different stratigraphic age, along with abnormal formation pressure gradients of stratum and other unusual circumstances.
Mr. Haodong Chen, the general manager of the Engineering Technology & Operation Center of CNOOC Hainan Branch, presented: “On the basis of securing operation safety and quality of well construction, the offshore drilling team performed precised analysis and judgment for the geological conditions of the sector in advance, together with innovated operating tools and explored the potential capabilities of drilling equipment to promote the continuous improvement of drilling efficiency.”
CNOOC has been making greater efforts to promote the applications of digital intelligent technology in the field of accelerating offshore oil and gas well drilling. The offshore drilling technical team relies on the “drilling optimization system” which was developed by themselves, through which it can promptly review the historical data of varies sectors of oil and gas wells drilling and made more scientific and reasonable operational decisions for the complicated well conditions.
Mu gihe cy'igihe cy' "Igikorwa cy'Imyaka itanu ya 14", CNOOC yateje imbere cyane umushinga wo kongera ububiko n'ibikorwa by'ibikomoka ku ngufu. Umubare w'ibikorwa byo gucukura amabuye y'agaciro ku nyanja wageze hafi 1,000 ku mwaka, bingana n'inyongera ya 40% ugereranije n'igihe cy' "Igikorwa cy'Imyaka itanu ya 13". Muri ayo mabuye y'agaciro yarangije, umubare w'amabuye y'agaciro acukurwa mu mabuye maremare n'amabuye y'agaciro y'ubujyakuzimu, amabuye y'agaciro afite ubushyuhe bwinshi n'igitutu, n'ibindi bintu bishya byari kabiri y'igihe cy' "Igikorwa cy'Imyaka itanu ya 13". Umusaruro wose wo gucukura no kurangiza wiyongereyeho 15%.
