On March 9, 2023, Gole 3C well was drilled in Fuman Oilfield, Tarim Basin. This is the largest ultra-deep oil field in China: Fuman Oilfield, a key well for expanding to ultra-deep strata. The vertical depth of the well is 8,060 m and the horizontal displacement is nearly 1,561 m. This well sets a new record for the deepest horizontal well in Asia. The ultra-deep marine carbonate rocks in Tarim Basin are rich in oil and gas resources, and the largest weathering crust oil fields and the largest condensate gas fields in China have been discovered one after another. The practice and research of exploration and development in Fuman Oilfield show that Fuman Oilfield is rich in oil and gas reservoirs with good oil properties and high production per well. The completion of Gole 3C well indicates that the oilfield development in Tarim Basin has entered a new stage of 9,000 m extra-deep oil and gas exploration and development.

The overuse of organophosphorus pesticides on cotton production is a big concern in China today. Therefore, developing methods for the rapid screening and confirming of pesticide residues in textiles has become a top public health security priority. Here, a method was established for the rapid screening and quantifying of 11 kinds of organophosphorus pesticides (ethoprophos, coumaphos, profenofos, diazinon, ethion, parathion, phosalone, quinalphos, dicrotophos, azinphos methyl, and tribuphos) in textiles by high-performance liquid chromatography high-resolution mass spectrometry (HPLC-HRMS). Rapid screening and quantifying could be completed by using software of Peakview and MultiQuant. Samples were extracted by the method of modified QuEChERS (Quick, Easy, Cheap, Effective, Rugged and Safe) and analyzed in the positive mode with MS detection. The results showed that the limits of detection were between 0.1 and 5.0 ng g−1, with correlation coefficients above 0.9990. The recoveries were in the range of 70.3 – 109.8%, with relative standard deviations from 5.1 to 16.4%. This method is accurate and simple, which can be used in the rapid screening and quantitative analysis of 11 kinds of organophosphorus pesticides in textiles.
