Hole sealing agent for seismic exploration and method of manufacturing the same

Abstract

The invention belongs to the seismic exploration technical field, in particular relating to a hole sealing agent and a preparation method thereof. The seismic exploration hole sealing agent is characterized in that the agent is prepared by superburning calcium oxide, cement with a strength grade more than 32.5 and an inorganic material; the raw materials by weight percentage of the hole sealing agent are: 40 to 97 percent of the superburning calcium oxide, 2 to 40 percent of the cement with the strength grade more than 32.5, and 1 to 30 percent of the inorganic material which is ganister sand or heavy calcium powder. The hole sealing agent has the advantages of simple construction, low difficulty to master, good sealing effect, safe use and low cost, etc.

Description

Technical field [0001] The invention belongs to the technical field of seismic exploration, and specifically relates to a plugging agent and a preparation method thereof, and is suitable for plugging the seismic source blasthole of seismic exploration. Background technique [0002] In the engineering application of seismic source blast hole plugging, whether the conventional seismic source blast hole is plugged with debris, sand, water or other mixed materials, it is a natural plugging method without prestress. There are many kinds of blocking materials, but the effect is not satisfactory. Conventional blockages are detritus. Sometimes due to groundwater, the construction unit simply does not block it, and directly uses water to block the cartridge. This method has a great impact on the accuracy and depth of seismic exploration. The principle of seismic exploration is to use all seismic waves to propagate to the formation. The quality of the blockage directly affects the amount...

Problems solved by technology

If the blockage is not dense, it will first affect the downward effect of the initial wave, and the detection depth will also be reduced; secondly, it will also affect the accuracy of the reflected wave. After the explosive detonates, the main wave propagates downward, and part of the wave propagates upward. , the energy of this part of the wave is very large and cannot be ignored. After these waves reach the surface, a small part of them is transmitted and most of them are reflected, and the reflected waves will be superimposed with the waves reflected back from the main wave, which will affect the parameters of the seismic wave. Misjudgment may occur when the device analyzes these parameters; in addition, if the wave energy reaching the surface is too large, it will directly affect the safety of the ground environment; again, if the blockage is not dense, there will be punching holes, which will bring hazards such as flying stones, which is a Security risks
