【摘要】：氮氣鉆井技術(shù)隸屬于氣體鉆井技術(shù),是一種科技含量較高、工程效果較好的欠平衡鉆井技術(shù),但是在鉆井過程中,沖蝕和腐蝕的交互作用將造成井口、欠平衡裝置、鉆桿、套管及地面管線的短期損傷失效,這就需要尋求一種方法有效的解決氮氣鉆完井過程中沖蝕失效問題。于是本文提出了氮氣鉆完井井口裝置與管柱材料沖蝕性能研究的問題。由于氮氣鉆完井過程中,沖蝕作用將造成井口、欠平衡裝置、鉆桿、套管及地面管線的短期損傷失效,需要建立沖蝕試驗裝置,研究工況環(huán)境條件對不同井口制造材料(包括多種防沖蝕設(shè)計的合金、硬質(zhì)合金涂層、四通等)的沖蝕影響規(guī)律及特征,明確井口裝置的沖蝕機理。給出適合油田井口裝置的沖蝕建議,以解決氮氣鉆完井過程中沖蝕失效問題,這對于油田的順利開發(fā)及安全生產(chǎn)具有十分重要的意義。本論文通過對井口裝置沖蝕機理分析,建立沖蝕實驗裝置,針對不同工況對材料進行沖蝕實驗并結(jié)合模擬試驗研究,提出井口裝置預(yù)防沖蝕的結(jié)構(gòu)設(shè)計和優(yōu)化其表面處理強化工藝,降低沖蝕的危害。并依據(jù)沖蝕試驗數(shù)據(jù)和建立的定量判定模型,為氮氣鉆井和完井工藝的安全實施提供可靠技術(shù)依據(jù),以保證油田的安全開發(fā)。
[Abstract]:Nitrogen drilling technology belongs to gas drilling technology. It is a kind of underbalanced drilling technology with high technology content and good engineering effect. However, in the drilling process, the interaction of erosion and corrosion will result in wellhead, underbalance device, drill pipe, The short term damage failure of casing and surface pipeline requires an effective solution to the erosion failure during nitrogen drilling and completion. In this paper, the problem of erosion performance of nitrogen drilling and completion well head device and pipe string material is put forward in this paper. Due to the short term damage failure of wellhead, underbalance device, drill pipe, casing and surface pipeline caused by erosion during nitrogen drilling and completion, it is necessary to establish a erosion test device. The effects of working conditions on the erosion of different wellhead materials (including many kinds of erosion-resistant alloys, cemented carbide coatings, four-way etc.) were studied, and the erosion mechanism of wellhead devices was clarified. In order to solve the problem of erosion failure during drilling and completion of nitrogen gas, it is of great significance for the smooth development and safe production of oil fields. In this paper, the erosion mechanism of the wellhead device is analyzed, and the erosion experiment device is established. The erosion experiment is carried out on the materials under different working conditions and combined with the simulation test. The structure design of the wellhead device for preventing erosion and optimizing its surface treatment and strengthening technology are put forward to reduce the damage of erosion. Based on the erosion test data and the established quantitative judgment model, the reliable technical basis is provided for the safe implementation of nitrogen drilling and completion process in order to ensure the safe development of oil fields.
