摘要： Recovery of hydrocarbon fluid from low permeability sources enhanced by introduction of a treating fluid is described. The treating fluid may include one or more constituent ingredients designed to cause displacement of hydrocarbon via imbibition. The constituent ingredients may be determined based on estimates of formation wettability. Further, contact angle may be used to determine wettability. Types and concentrations of constituent ingredients such as surfactants may be determined for achieving the enhanced recovery of hydrocarbons. The selection can be based on imbibition testing on material that has been disaggregated from the source formation.

摘要： A method is given for treating a wellbore to increase the production of hydrocarbons from a subterranean formation penetrated by a wellbore, involving a period of injecting into the formation an aqueous injection fluid having a different chemical potential than the aqueous fluid in the formation. If there is water blocking, an osmotic gradient is deliberately created to cause flow of water into the injected fluid; hydrocarbon is then produced by imbibition. If the pore pressure in the water-containing pores in the formation is too low, an osmotic gradient is deliberately created so that water flows from the injected fluid into the water-containing pores, increasing the pore pressure and facilitating hydrocarbon production by imbibition. The method may be repeated cyclically. A semipermeable membrane may be created to enhance the osmosis. Wetting agents may be used to influence imbibition.
摘要翻译：给出了一种处理井眼以增加从井眼穿透的地下地层生产烃的方法，包括向地层中注入具有与地层中的含水流体不同的化学势的含水注入流体的时期。如果有阻水现象，则故意制造渗透梯度以引起水流入注入的流体; 然后通过吸入来生产碳氢化合物。如果地层中含水孔隙中的孔隙压力太低，则故意产生渗透梯度，使得水从注入的流体流入含水孔隙中，增加孔隙压力并通过吸入促进烃类生产。该方法可以循环重复。可以创建半透膜以增强渗透。润湿剂可用于影响吸液。
