摘要:
为寻求射孔弹在碳酸盐岩中的穿透规律以及岩石性质对射孔穿深的影响,开展了不同抗压强度碳酸盐岩射孔弹地面打靶试验和不同围压下碳酸盐岩、砂岩射孔弹高温高压打靶试验。试验结果表明:对于碳酸盐岩储层,岩石抗压强度、围压以及温度对射孔穿深的影响规律与砂岩储层一致;抗压强度越大,围压越大,射孔穿深越小,在射孔弹耐温指标范围内,温度对射孔穿深的影响非常有限;在相同抗压强度和相同围压的条件下,射孔弹在碳酸盐岩的射孔穿深低于在砂岩储层中的射孔穿深;岩石抗压强度、围压以及岩石性质是影响射孔弹地下实际穿深的3个最重要因素。
Abstract:
In order to understand the dependence of perforating penetration depth on the properties of carbonate reservoir, especially the rock properties, charge testing was carried out on carbonate rocks with different compressive strengths and under various levels of applied effective stress, and on sandstone rocks at high temperature and high pressure. Experimental results show that the influence of rock compressive strength, effective stress and temperature on the penetration depth in carbonate reservoir and sandstone is consistent. The greater the compressive strength and the effective stress were, the smaller the perforating penetration depth would be. The influence of temperature on perforating penetration depth is very limited within the scope of temperature resistance index of perforating charge. The perforating penetration depth in carbonate reservoir is lower than that in sandstone reservoir when their compressive strengths and effective stresses are same. Rock compressive strength, effective stress and rock nature are the three most important factors guarding the underground penetration depth of shaped charges.
