摘要:
针对深层石油勘探，考虑到既要满足震源产生足够的能量、又不能破坏石油套管的技术要求，优化筛管式炸药震源的结构，分别通过数值模拟和地面实验的方法，分析装药直径、筛管孔隙率、装药壳体壁厚等参数对筛管式震源能量的影响规律。结果表明：在一定范围内，孔隙率越高，筛管的胀径越大。优化后，采用孔径15 mm、 孔间距50 mm、环向 8孔的方案，且壳体壁厚不小于 8 mm。
Abstract:
For deep oil exploration, considering the technical requirements of producing sufficient energy from the seismic source without damaging the oil casing, the structure of the sieve tube seismic source has been optimized. The influence of parameters such as charge diameter, sieve tube porosity, and wall thickness of charge shell on the energy of sieve tube seismic sources was analyzed by numerical simulation and ground test methods. The results show that in a certain range of porosity conditions, the higher the porosity, the larger the expansion diameter of sieve tube. After optimization, the aperture is 15 mm, the spacing between holes is 50 mm, and there are 8 holes in the circumferential direction, with a shell wall thickness of not less than 8 mm.
