【摘要】：油田注水開發(fā)進入中后期,由于地層非均質(zhì)性的影響,造成注入水沿高滲透層突進,導(dǎo)致油井含水上升快、水淹早、注入水波及中低滲透層的程度低,水驅(qū)開發(fā)效果差。若對注水井的吸水剖面進行調(diào)整(即調(diào)剖),可達到改善開發(fā)效果的目的。礦場調(diào)剖實踐中所用的一類主要調(diào)剖劑是預(yù)交聯(lián)體膨型顆粒調(diào)剖劑,由于其具有操作簡便、工藝簡單等優(yōu)點,在國內(nèi)各大油田的使用量急劇上升。本文針對我國多數(shù)油田注水井調(diào)剖過程中存在油藏埋藏較深、礦化度高等技術(shù)難題,在實驗室合成了一種新型調(diào)剖劑——QL-HVES緩膨抗鹽吸水高黏彈顆粒調(diào)剖劑,并通過各組份濃度的影響確定了該新型調(diào)剖劑的最佳配方。通過靜態(tài)和巖心流動實驗,系統(tǒng)評價了該調(diào)剖劑在不同礦化度和不同溫度條件下的強度、熱穩(wěn)定性、抗鹽性能、吸水性能、保水性能。室內(nèi)實驗結(jié)果表明:新合成的這種調(diào)剖劑具有良好的黏彈性和柔性,此外,還具有良好的緩膨和抗鹽效果,其綜合性能可以滿足不同油層條件下調(diào)剖作業(yè)要求。在完成室內(nèi)研究的基礎(chǔ)上,2012年8月使用新合成的QL-HVES緩膨抗鹽吸水高黏彈顆粒調(diào)剖劑在姬塬油田羅1區(qū)地197-45井組進行了現(xiàn)場實驗,取得了良好的增油降水效果。
[Abstract]:In the middle and late stage of oilfield water injection development, due to the influence of formation heterogeneity, the injection water burst along the high permeability layer, resulting in the oil well water cut rising quickly, water flooding early, the degree of injection water wave and low permeability layer is low, and the effect of water drive development is poor. If the water absorption profile of the injection well is adjusted (I. E. profile control), the development effect can be improved. One of the main profile control agents used in the field profile control practice is the pre-cross conjoined expanded particle profile control agent. Because of its advantages of simple operation and simple process, the usage of profile control agent in various oil fields in China has increased sharply. In view of the deep reservoir buried in the profile control process of water injection wells in most oilfields in China, a new profile control agent, QL-HVES, is synthesized in the laboratory, which is a new type of profile control agent with low salt and water absorption and high viscoelastic particles. The optimum formulation of the new profile control agent was determined by the influence of each component concentration. Through static and core flow experiments, the strength, thermal stability, salt resistance, water absorption and water retention of the profile control agent under different salinity and temperature were systematically evaluated. The results of laboratory experiments show that the new profile control agent has good viscoelasticity and flexibility, in addition, it has a good effect of slow swelling and salt resistance, and its comprehensive performance can meet the requirements of down-profile operation under different reservoir conditions. On the basis of the laboratory study, a field experiment was carried out in August 2012 with a newly synthesized QL-HVES salt absorbent and high viscoelastic granular profile control agent in well 197-45 of Luo1 area, Jiyuan Oilfield, and a good effect of increasing oil and reducing water was obtained.
