Protective Test Fluid for Deepwater Reservoir:Study and Application in Block Lingshui17-2
-
摘要: 根据南海北部深水区储层特征及温度压力条件,对适合LS17-2-1井的测试液进行了优选。络合剂HWLH能通过分子内和分子间与水分子形成氢键,使水分子内和水分子间形成网络结构而成为络合水。以络合剂HWLH为核心处理剂配制了络合水测试液,该络合剂能阻止测试液中的水与地层中的水相互迁移,从而保证其优良的抑制性、防水锁性及储层保护特性。室内评价结果表明,络合水测试液不仅具有较好的流变性、防水敏性、防水锁性(气-液表面张力为25.7~25.9 mN/m)、防腐性和气体水合物抑制性,与前期工作液、非储层段测试液和地层水均具有较好的配伍性,而且具有优良的储层保护性和自返排能力。络合水测试工作液在陵水17-2-1井测试作业中成功应用,证明了该体系的适应性和可行性。Abstract: Individule water molecules can form complexed water through intramolecular and intermolecular networking by hydrogen bonds between HWLH, a complex agent, and water molecules. HWLH has the ability to stop water from migration between test fluid (containing HWLH) and formation, protecting reservoirs from being damaged. Laboratory studies show that HWLH test fluid has good rheology, inhibitive capacity, water block prevention capacity (air-liquid interfacial tensions are 25.7-25.9 mN/m), low corrosion and good gas-hydrate inhibition. HWLH test fluid is compatible with early stage work fluids, test fluids for non-reservoir sections and formation water. HWLH test fluid has been successfully used in testing of the gas well Lingshui 17-2-1.
