    摘要： A gas operated seismic source has a rigid elongated cylindrical form and includes at least a single, hollow, thick wall barrel along most of the central length thereof, wherein the internal volume defines therein a combustion chamber. The barrel has a plurality of perforations formed along its length of a selected number, size or sizes, and arrangement. An inflatable member is secured at either end thereof about the perforated barrel to enclose the perforations and define accordingly an expandable outer wall about the combustion chamber. The perforated barrel has a substantially constant diameter as does the inflatable member, and the barrel supports the inflatable member when in its collapsed state. Thus the outside dimensions of the entire length of the source are substantially constant to allow the source to be readily forced or ''''planted'''' into and also retrieved from a consolidated or an unconsolidated formation, or to readily allow inserting the source into a predrilled hole in a consolidated formation. Means are provided to introduce a preselected mixture of combustible fuel into the combustion chamber. Upon firing, the burned gases are forced out an exhaust means by the explosion and the subsequent charge of combustible fuel, or the combustion chamber is purged by employing vacuum or pressure.

    摘要翻译： 气体操作的地震源具有刚性细长的圆柱形形状，并且在其中心长度的大部分上包括至少一个中空的较厚的壁筒，其中内部容积在其中限定有燃烧室。 枪管具有沿着其选定数量，尺寸或尺寸和布置的长度形成的多个穿孔。 可膨胀构件在其任一端处围绕穿孔的圆柱体固定以包围穿孔并且相应地限定围绕燃烧室的可膨胀的外壁。 穿孔筒体具有与充气构件一样的基本上恒定的直径，并且当处于其折叠状态时，筒体支撑可膨胀构件。 因此，源的整个长度的外部尺寸基本上是恒定的，以允许源容易地被强制或“种植”到固结的或未固结的地层中，也可以容易地将源插入到预钻孔中 综合组合。 提供装置以将可燃燃料的预选混合物引入燃烧室。 在燃烧时，燃烧的气体通过爆炸和随后的可燃燃料的加载被排出排气装置，或者通过使用真空或压力来清除燃烧室。
