【技术实现步骤摘要】
一种勘探钻头
本技术涉及石油勘探
,特别涉及一种勘探钻头。
技术介绍
现有技术中,在开发石油气前,往往先要对储层进行取样,分析土壤和油气的情况。但是现有技术中,在石油气勘探领域还没有一种能够在钻井打洞取样时,同时实现打洞钻进、返土取样、油样气样通用采集获取的勘探钻头。
技术实现思路
本技术的目的是提供一种勘探钻头,能够在钻井打洞取样时,同时实现打洞钻进、返土取样、油样气样通用采集获取。本技术的上述目的可采用下列技术方案来实现:一种勘探钻头,其特征在于:该勘探钻头包括取样管,钻杆,螺旋刀和钻头;所述钻头为带空腔的钻头,包括带空腔的主钻头体和钻头套,所述钻头套套设在所述主钻头体的下部,两者活动连接,可相对旋转;所述钻杆与所述钻头固定连接;所述取样管设置在所述钻杆的内部,与所述主钻头体的空腔相连通;所述螺旋刀沿着钻杆由上到下螺旋盘绕延伸至钻头处;所述主钻头体的底面设置有至少1个的带滤网的弧形腔孔,所述弧形腔孔联通外界和主钻头体的空腔;所述主钻头体的底部、在钻头的旋转前进方向上、位于弧形腔孔的后端设置有一把钻刀;所述钻头套底面设置有与所述钻刀相匹配的多功能滑槽,所述钻刀能够 ...
