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。

摘要： A method for determining wettability of a solid, such as a reservoir rock material, is described. The method includes disaggregating the material, for example by grinding and placing the disaggregated material on the surface of the fluid. The wettability is analyzed based on whether a portion of the material floats on or sinks into the fluid. The method is well suited for heterogeneous solid materials that have mixed wetting characteristics and/or have varying surface types. The fluid can be evaluated as a potential treatment fluid or a component thereof that can be used for treating the rock formation. For example, the potential treatment fluid can include a surfactant or an oxidizing agent. A simple observation can be made whether substantially all of the material placed on the surface of the fluid sinks into the fluid, or the portions of floating and sinking material can be weighed.

摘要： A method for determining a characteristic of an underground formation with a fluid is described. The method includes providing a sample material of the underground formation; measuring the permeability and the porosity of the sample material; performing a drainage test on the sample material using the fluid; estimating the threshold pressure of the sample material from the drainage test, the permeability and the porosity measurements; and determining the receding contact angle of the fluid on the sample material from the threshold pressure. The sample material can be disaggregated material.

摘要： A method of determining wettability of a rock sample, such as from a core sample is described. The sample is preferably crushed or comminuted to a particulate size where micro fractures have been eliminated, but where the particles are still large enough to represent the native rock matrix and texture. The comminuted core sample is exposed to a test fluid for a given period of time. The rock sample can be split into many separate aliquots, and a series of tests is performed using a series of different fluids and/or the same fluid for different exposure times. The excess test fluid residing on the surfaces of sample particles is removed. The test fluid imbibed into the interior of the particulate sample is then measured. The test fluid can be, for example, water, a non-aqueous fluid, and/or a solution of miscible solvents. The technique used to measure the imbibed fluid depends on the solvent (imbibing fluid) being studied. In one example, this technique includes both gravimetric determination and quantitative chemical analysis. The detection of water can be via Karl Fischer titration.
