【摘要】:石油鉆機是指在油氣勘探中,帶動鉆具向地下鉆進,用于鉆取巖心、礦心、巖屑、氣態(tài)樣、液態(tài)樣等,以探明地下地質和礦產(chǎn)資源等情況的機械設備。在油氣勘探開發(fā)過程中起著至關重要的作用。隨著石油工業(yè)的不斷發(fā)展,在人工島及近海陸地施工的石油鉆機逐年增多,因常年受海洋大氣、海水飛濺等腐蝕,石油鉆機的額定載荷下降、鉆井能力降低,鉆采配件的使用年限縮短,其維修成本逐年增加。本文分析和研究了應用于石油鉆機設備上的常用防腐方案和近年新發(fā)展的各種防腐方法,并根據(jù)近海陸地石油鉆井機(ZJ90DB鉆機)的不同區(qū)域、設備的不同功能及特性,設計使用包括冷噴鋅、熱浸鋅、環(huán)氧富鋅噴涂、外覆防腐漆,達克羅處理、采用不銹鋼材質的緊固件等多種適合近海石油鉆機防腐方案,研究并細化了石油鉆機設備表面處理及噴涂施工的工藝流程,通過嚴格控制漆膜厚度,施工工序,保證設備的防腐質量。本文提出并進一步發(fā)展了石油鉆機在現(xiàn)場使用過程中的延遲腐蝕方法。根據(jù)鉆機不同部位,不同防腐要求制定了適用于鉆井現(xiàn)場環(huán)境,適合于鉆井隊工人施工的切實可行的修補涂裝方案及修補工藝流程,細化石油鉆機被腐蝕、刮碰處的現(xiàn)場有效修補及二次防腐技術,能進一步降低設備腐蝕速率,減少工人勞動強度,提高鉆機使用年限,保障設備本質安全。并為其它近海石油設備的防腐提供參考借鑒作用。有著較好的應用前景。
[Abstract]:In oil and gas exploration, the oil rig is used to drive the drilling tools underground to drill for cores, cores, cuttings, gaseous samples, liquid samples, etc. With the development of petroleum industry, the number of oil drilling rigs constructed on artificial islands and offshore land increases year by year, which plays an important role in the exploration and development of oil and gas. As a result of the perennial corrosion caused by the ocean atmosphere and sea water spatter, the rated load of the oil drilling rig has decreased, the drilling capacity has been reduced, and the service life of the drilling and production accessories has been shortened. The maintenance cost is increasing year by year. This paper analyzes and studies the common anticorrosion schemes applied to oil drilling rig equipment and various new anticorrosion methods developed in recent years, and according to the different regions of the offshore terrestrial oil drilling rig ZJ90DB drilling rig, Different functions and characteristics of the equipment, including cold spray zinc, hot dip zinc, epoxy zinc-rich spraying, coating anticorrosion paint, Dacromet treatment, stainless steel fastener and other anti-corrosion schemes suitable for offshore oil drilling rig. The process flow of surface treatment and spraying construction of oil drilling rig equipment is studied and refined. By strictly controlling the thickness of paint film, the construction procedure, This paper puts forward and further develops the delayed corrosion method of oil drilling rig in field operation. According to different parts of drilling rig, different requirements of corrosion protection are formulated for drilling site environment. The feasible mending and coating scheme and repair process suitable for drilling team workers can further reduce the corrosion rate of equipment by refining the corrosion of oil drilling rig, effective repair and secondary anticorrosion technology on the spot of scrape and collision. It can reduce the labor intensity of workers, improve the service life of drilling rig, guarantee the essential safety of equipment, and provide reference for other offshore petroleum equipment. It has a good application prospect.
