【摘要】：胡153區(qū)塊侏羅系油藏自注水開發(fā)以來,注入水沿著高滲帶、大孔道和裂縫產(chǎn)生指進或錐進,導(dǎo)致主向井水淹嚴(yán)重、側(cè)向井水驅(qū)不均,油井過早見水。隨著油田開發(fā)時間的延長,這種矛盾越來越突出,成為影響該油田穩(wěn)產(chǎn)的主要因素之一。雖然該區(qū)曾通過壓裂的方式來增產(chǎn),但是控水穩(wěn)油效果不理想,因此考慮對該區(qū)油井采取更為有效的堵水措施。本文以胡153區(qū)塊侏羅系油藏地質(zhì)特征和油藏數(shù)據(jù)為基礎(chǔ),通過對國內(nèi)外堵水技術(shù)的調(diào)研及該區(qū)油井見水規(guī)律的分析,開展了室內(nèi)堵劑配方優(yōu)選實驗。優(yōu)選出弱凝膠堵水劑(體系配方為2000mg/L主劑+0.2%交聯(lián)劑+0.25%穩(wěn)定劑)、強凝膠堵水劑(體系配方為15%AM+0.1%交聯(lián)劑+8%增強劑+0.14%引發(fā)劑)以及預(yù)交聯(lián)體膨顆粒三種堵劑體系。通過靜態(tài)實驗和巖心實驗對堵劑體系的成膠性能、抗鹽性、抗剪切性、長期穩(wěn)定性、封堵能力等進行了評價。實驗結(jié)果表明,弱凝膠和強凝膠堵劑的封堵性能好、耐鹽性高、抗剪切能力強,對不同滲透率巖心都能進行封堵。預(yù)交聯(lián)顆粒粒徑可控,能夠選擇性地封堵水層,而不封堵油層。同時還對現(xiàn)場施工工藝參數(shù)進行了設(shè)計。設(shè)計的施工參數(shù)為:注入壓力控制范圍為10~20MPa,施工排量控制范圍為3~5m3/h;段塞組合方式為:前置段塞+主段塞+保護段塞+注入水的組合方式。該優(yōu)化工藝對于改善胡153區(qū)塊侏羅系油藏的水驅(qū)開發(fā)效果、增加原油產(chǎn)量和提高采收率都具有重要意義。為進一步開展胡尖山油田侏羅系油藏的調(diào)剖堵水作業(yè)提供了寶貴經(jīng)驗。
[Abstract]:Since the development of the Jurassic reservoir in the Hu 153 block, the injection water has been brought into or coning with the high permeability zone, large pore channel and crack, which leads to serious flooding in the main well, the lateral well water flooding is unevenly, and the oil well sees water too early. With the extension of the oilfield development time, this contradiction becomes more and more obvious, which has become one of the main factors affecting the stable production of the oil field. However, the area has been increased by fracturing, but the effect of water control for water stabilization is not ideal. Therefore, more effective water plugging measures are taken to the oil wells in this area. Based on the geological characteristics and reservoir data of the Jurassic reservoir in the Hu 153 block, the study of water plugging technology at home and abroad and the analysis of the law of water production in the oil well in this area have been carried out in this paper. Optimization of the formula of internal plugging agent. The weak gel water plugging agent (system formula is 2000mg/L main agent +0.2% crosslinker +0.25% stabilizer), strong gel water plugging agent (system formula is 15%AM+0.1% crosslinker +8% reinforcing agent +0.14% initiator) and three kinds of plugging agent system of preformed joint expanded granule. The formation of plugging agent system by static experiment and core experiment The adhesive properties, salt resistance, shear resistance, long-term stability and plugging ability were evaluated. The results showed that the blocking properties of the weak gels and the strong gel plugging agents were good, the salt resistance was high, the shear ability was strong, and the core of different permeability cores could be blocked. The size of the pre crosslinked particles was controllable, and the water layer could be selectively blocked, not blocking the oil layer. At the same time, the parameters of the field construction process are designed. The construction parameters are as follows: the control range of injection pressure is 10~20MPa, the control range of construction displacement is 3~5m3/h, and the combination mode of slug is the combination of pre slug + main slug + protective slug + injection water. This optimization process is used to improve the water flooding of Jurassic reservoir in Hu 153 block. It is of great significance to increase the oil production and increase the oil recovery. It provides valuable experience for further development of profile control and water plugging in the Jurassic reservoir of the Hu Jianshan oilfield.
