摘要
采用数值模拟方法计算了两种不同装药结构的89型震源弹在10.0、21.0 mm和32.0 mm不同间隙下对套管的侵彻伤害程度,并对满足技术要求的方案进行地面模拟侵彻套管和震源枪模拟井试验。结果表明:在10.0 mm间隙下,数值模拟计算侵彻深度比试验结果深1.7 mm;在21.0 mm和32.0 mm间隙下,数值模拟和试验的侵彻深度相同,说明了数值计算结果与试验结果吻合性较好。新设计的震源弹在震源枪身形成平均直径为22.3 mm的孔眼,满足向地层迅速释放爆炸能量、激发地震波且不损伤套管的要求。
The damage degree of casing penetration by two kinds of 89-type seismic source bombs with different charge structures under different clearance of 10.0, 21.0 mm and 32.0 mm was calculated by numerical simulation method. Ground penetrating casing and seismic gun simulation well tests were carried out for the schemes that meet the technical requirements. Results show that the simulated penetration depth at 10.0 mm clearance is 1.7 mm deeper than the test results, and the depth at 21.0 mm and 32.0 mm clearance is the same, which shows that the numerical results are in good agreement with the experimental results. The newly designed seismic source bomb forms holes with an average diameter of 22.3 mm in the seismic gun barrel. Which can release explosive energy to the ground quickly and excite seismic waves without damaging the casing.
