Problems solved by technology

However, the commonly used measurement-while-drilling methods currently lack the direct detection of hydrocarbon fluids in downhole oil and gas reservoirs, and no corresponding detection instruments and methods have been developed, so it is impossible to directly judge and understand oil and gas reservoirs during the drilling process

Embodiment Construction

[0035] In order to make the technical solutions and advantages of the present invention clearer, the exemplary embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings. Apparently, the described embodiments are only a part of the embodiments of the present invention, and are not exhaustive of all the embodiments. And in the case of no conflict, the embodiments and the features in the embodiments of the present invention can be combined with each other.

[0036] figure 1 A downhole drilling fluid hydrocarbon detection instrument according to an embodiment of the present invention is schematically shown, including a drill collar body 1 . The drill collar body 1 is connected to the drill collar string of the drill string 11 not far from the drill bit 12, and is lowered into the wellbore 13, and its interior is used to carry other components. An inspection module is arranged on the drill collar body 1, and the i...

Abstract

The invention provides an instrument for detecting hydrocarbons in underground drilling fluid while drilling, which belongs to the field of oil-gas exploration and comprises a drill collar body. The detection module is arranged on the drill collar body, absorbs drilling fluid underground and detects the hydrocarbon content in the drilling fluid; the control and data transmission module is arranged on the drill collar body, and the control and data transmission module controls the detection module to detect the hydrocarbon content and transmits detected data to the ground through the MWD module. The device can be tripped into a well while drilling, underground detection while drilling is achieved, the original state of hydrocarbon in underground drilling fluid is guaranteed to the maximum extent, and hydrocarbon fluid such as oil gas in a reservoir is directly detected.

Description

technical field [0001] The invention relates to an instrument for detecting hydrocarbons in downhole drilling fluid while drilling, which belongs to the field of oil and gas exploration. Background technique [0002] The main purpose of oil exploration is to find downhole oil and gas reservoirs or other resources, and the main method used is to connect the ground and downhole oil and gas passages through drilling. During the drilling process, the risks faced are relatively high, and the cost is also high. Therefore, on the basis of effectively discovering underground oil and gas reservoirs, improving drilling efficiency, reducing drilling risks, and ensuring drilling safety are important oil and gas exploration and development tasks. [0003] The current status and problems of discovering oil and gas, ensuring drilling, and improving timeliness are mainly as follows: [0004] First, after drilling and breaking the rock formation, the oil and gas in the rock formation are c...
