Especially the perforating technology in the exceptional horizontal wells such as slim - hole casing wells , large hole wells and complex wells is detailed 着重介绍了水平井射孔技术在小井眼、大井眼及复杂井况条件下特殊井中的技术要求和特点。
On the basis of having success , such a test for raising penetration rate and reducing comprehensive drilling cost was also carried out in two small diameter holes , and a good result was achieved 在成功试验的基础上，开展了2口提高钻井速度、降低钻井综合成本的小井眼天然气欠平衡钻井试验，取得了较好的应用效果。
Through analyzing it is shown that the fuzzy consistent matrix method is conformable to the people ' s thinking and deciding mode and it is effective to evaluate multi - objective drilling plan of slimhole by use of such a method , thus providing a reliable basis for scientific decision , so it is of a vast range of prospects 分析结果表明模糊一致矩阵法符合人们思维决策的一致性，它能有效评价小井眼的多目标钻井方案，为科学决策提供了可靠的科学依据，因而具有广泛的应用前景。
After having analyzed and evaluated the ten indexes in multi - objective plan of slimhole drilling by use of fuzzy consistent matrix method according to the fuzzy consistent relation theory , the preferential sequence of four plans is exactly indicated in the paper , which is identical with the fuzzy arrangement evaluation model of slimhole drilling 摘要根据模糊集中的模糊一致关系理论，运用一致矩阵法，对小井眼钻井多目标方案10个指标进行评价分析后，明确指出四种方案的优先顺序，这与小井眼钻井模糊层次评价模型一致。
Through prediction to water cut of two individual producing oil layers of saii7 + 8 and pui1 + 2 in 501 well in close well spacing test area of daqing oil field , and verification by individual layer test data in dense well pattern test area in west part of central area , its result coincide well with actual water cut 通过对大庆油田小井距试验区501井萨7 + 8和葡1 + 2两个单采油层含水率的预测及中区西部密井网试验区单层测试资料的验证，其结果与实际含水率符合较好。
