Description
Technical Field
The invention relates to a gas detection device for logging, and belongs to the technical field of gas detection devices.
Background
In the petroleum exploitation process, the detection of stratum fluid is an important means for identifying the abnormality of oil gas, the oil gas can be quickly identified and found by carrying out gas detection through an on-site logging method, and meanwhile, the monitoring and early warning of toxic and harmful gas can be carried out, and non-hydrocarbon gas reservoirs can also be found.
Currently, there are two types of methods for gas detection in formations. The first is to directly put the gas detector at the drill bit, and to put the gas detector into the bottom of the well along with the drilling tool, and to detect the gas of the stratum when the drilling tool encounters the stratum in real time during the drilling process; the detection result obtained by the method has small distortion and good instantaneity; however, there is no practical product available at present due to the limitations of the detector operating environment. The second method is to return the drilling fluid from the bottom of the well, carry the stratum drilling gas to the ground, remove the gas carried in the drilling fluid from the ground through a gas separation device, and detect the gas by a gas detector.
Taking a common pumping type gas detector as an example, the existing pumping type gas detector comprises a detector body, wherein an air pump and an air channel pipeline connector are arranged on the detector body, and an air channel pipeline is detachably connected to the air channel pipeline connector. When the gas detector detects, one end of the outlet of the gas separation device is connected to the joint of the gas path pipeline of the detector, at the moment, the air pump arranged in the detector body is started, the gas to be detected is sucked into the detector body through the gas path pipeline, and the detector body is also internally provided with a detection probe for detecting the gas.
However, the existing gas separation device is directly placed in the returning drilling fluid, and the gas in the drilling fluid is separated by a rotary stirring mode. Because the flow change range of the returning drilling fluid is large, the drilling fluid quantity processed by the gas separation device under different drilling fluid flows is large in change, and the accuracy of a gas detection result is affected. Although floating gas separation devices are present, due to the limitations of the drilling fluid environment in which the gas separation device is located, the floating effect is reduced and the labor intensity of operators is increased as the drilling fluid adheres to the gas separation device. And because of the change of drilling fluid flow, the existing gas separation device is easy to cause drilling fluid to enter the gas detector, so that the gas detector is damaged.
