摘要
阿塞拜疆Kursenge和Karabagli油田属于中温、低压、低孔、低渗油藏,需要采用必要的增产措施以获得较高的单井产量,提高油藏整体动用程度。由于储层属低压、强水敏,不利于水力压裂增产作业,经过伤害因素分析和研究,研制出了低伤害乳化压裂液。该压裂液有助于保护储层,降低伤害,达到改造储层、提高产量的目的。现场应用表明,乳化压裂液施工成功率达100%,压裂后增产有效率达83%,效果明显的达50%以上。
Stimulation measures are needed to develop the Kursenge and Karabagli oilfields to increase the per-well production. The reservoirs in the two oilfields are medium-temperature, low-pressure, low-porosity and low-permeability in nature. Hydraulic fracturing is not applicable in developing the reservoirs because of the low pressures and strong water sensitivity of the formations. An analysis and study on the formation damage gave birth to an emulsified fracturing fluid with low formation damage. Field applica...
