Wire-line coring drilling tool capable of acquiring occurrence information and method for acquiring occurrence information
The invention discloses a wire-line coring drilling tool capable of obtaining occurrence information and a method for obtaining the occurrence information, the drilling tool comprises a measuring short section, the measuring short section comprises a measuring inner pipe, a measuring outer pipe and a closed measuring box arranged in the measuring inner pipe, and the measuring inner pipe, the measuring outer pipe and the measuring box are all made of non-magnetic materials; a multi-point electronic inclinometer is fixedly arranged in the measuring box; the directional grooving mechanism is fixedly arranged in the core barrel and comprises a main nicking tool and two auxiliary nicking tools, and the main nicking tool and the two auxiliary nicking tools are distributed in the circumferential direction of the core barrel. The method for acquiring the occurrence information comprises the following steps: firstly, drilling a core sample through the wire-line coring drilling tool capable of acquiring the occurrence information; then taking out the rock core sample, and calculating occurrence information. The multi-point inclinometer is arranged to record the well deviation angle and the well deviation azimuth angle during coring, the linear groove is carved in the rock core sample through the main graver, occurrence information can be conveniently calculated after the rock core sample is obtained, the cost is low, and the efficiency of obtaining the occurrence information is high.
本发明公开了一种能够获取产状信息的绳索取心钻具及获取产状信息的方法，钻具包括：测量短节，测量短节包括测量内管、测量外管和设置在测量内管中的、密闭的测量盒，测量内管、测量外管及测量盒的材料都为无磁材料；测量盒内固设有多点式电子侧斜仪；固设在岩心管中的定向刻槽机构，定向刻槽机构包括一个主刻刀和两个副刻刀，主刻刀和两个副刻刀沿岩心管的周向分布。获取产状信息的方法：首先通过能够获取产状信息的绳索取心钻具钻取岩心样品；然后取出岩心样品，计算产状信息。通过设置多点式测斜仪来记录取心时的井斜角和井斜方位角，并通过主刻刀在岩心样品上刻直线槽，方便取得岩心样品后，计算产状信息，成本低，且获取产状信息的效率高。
