The invention discloses a system device for deepwater lake coring drilling. The system device comprises an overwater working platform, a propelling system, an anchoring system, a casing pipe system and a drilling system. Compared with the prior art, the overwater working platform of the device is reasonable in structure, horizontal thrust generated by stormy waves can be effectively dispersed andreduced through structural gaps of the overwater working platform, and the overwater working platform is balanced in stress, low in dead weight, safe and reliable; and the anchoring capacity of the anchoring system of the device is high. The casing pipe system of the device can be automatically straightened so as to counteract and balance the downward bending, inclining and falling force generatedby the self weight of a casing pipe, and the casing pipe can be kept in a vertical and stable state all the time in water, especially in deep water; and the casing pipe system can further be in buttjoint with or separated from the overwater working platform in real time, so that the influence of displacement of the drilling working platform system on the stability of the casing pipe is avoided.

    本发明公开了一种用于深水湖泊取心钻探的系统装置,包括水上工作平台、推进系统、锚固系统、套管系统和钻探系统。相比于现有技术,该装置的水上工作平台结构合理,其结构间隙可有效分散和降低风浪产生的水平推力,且受力均衡,自重较轻、安全可靠;该装置的锚固系统的锚固能力较强;该装置的套管系统能够自行扶正,以抵消和平衡套管因自重产生向下弯曲倾斜和倒伏的力量,实现套管在水中尤其是在深水中始终保持垂直稳定的状态;套管系统还能够与水上工作平台实时对接或脱离,以避免钻探工作平台系统的位移对套管的稳定产生影响。
