Feasibility Analysis of Spud Can Modification of Jack-up Drilling Platform to Reduce Puncture Risk DENG Chenghui, ZUO kun, YANG Zhan, LIU Chao, ZHANG Haitao 2023, 50 (8):  43-45.  Abstract ( 490 )   Save Jack-up drilling platform is an important equipment for offshore oil development. Puncture problem has always been a difficult problem for jack-up drilling platforms during pile insertion operations. At present,when the jack-up drilling platform is working,it is necessary to explore and analyze the target layer and predict the risk of pile insertion. Active puncture method can be adopted in strata with puncture risk to reduce the puncture risk of pile insertion operation. However,the active puncture method has a long operation cycle,and the drilling has problems such as backfilling and collapse. Taking EP 20-5 as an example,this paper puts forward the method of reducing the puncture risk by spud can modification,and compares and analyzes the puncture risk coefficient of HL9 drilling platform before and after spud can modification. The prediction results show that the modified spud can can effectively reduce the puncture risk,and the spud can modification is feasible in the method of reducing the puncture risk.

Maize has high nutritional value and is an excellent food crop. It is also one of the indispensable raw materials for food，health care，light industry，chemical industry and so on. Hybrid maize was used as experimental material，and the effects of simulated drought stress on the activities of superoxide dismutase （SOD），peroxidase （POD） and catalase （CAT） in the ear leaves and roots of hybrid maize were analyzed. The results show that with the increase of drought stress，the activities of SOD，POD and CAT in the ear leaves and roots of hybrid maize are gradually increased. The SOD activity of maize roots is higher than that of ear leaves in the control group and under various drought stress conditions. The POD activity of maize roots is higher than that of ear leaves in the control group and under various drought stress conditions. The CAT activity of maize ear leaves of is higher than that of roots in the control group and under various drought stress conditions. References | Related Articles | Metrics
