摘要:
渤海L油田馆陶组为低幅强边底水油藏,开采井网为水平井网。开发后期由于水平段压降和采出程度不均,导致边水或底水水窜,油井含水上升快,甚至出现暴性水淹,油井产量急剧下降。利用典型机理模型,研究水平井段存在高渗条带下的见水特征,得出含水率和水油比导数的变化规律。结合实际油藏数值模拟和水平井段物性参数,确定水平井见水位置。在此基础上,应用中心管控水技术,结合大泵提液,调整和改善水平段流量剖面,达到降水增油的目的。在渤海L油田试验实施2口井,平均单井产油量由5 m3/d提高到45 m3/d,累计增油6.3×104 m3,综合含水率由99%降至81%。该技术为海上边底水油藏水平井高含水期稳油控水开采探索了一条新的途径。
Abstract:
The Guantao Formation of L Oilfield in Bohai is a low amplitude and strong edge-bottom water reservoir, and the production well pattern is horizontal well one. At the late stage of development, the edge water or bottom water channeling was caused by uneven pressure drop and production level of the horizontal section. Thus, this may lead to fast rising water-cut, even appearing serious water flooding, and a steep decline in production in oil wells. A typical mechanism model was used to study the characteristics of water breakthrough in horizontal well section under high permeability zone. And then it was obtained the change rule between water-cut and derivative of water oil ratio. Combined with actual reservoir numerical simulation and physical parameters of horizontal wells, the location of water breakthrough in horizontal wells was further determined. On this basis, combined with the large pump extraction fluid, the water control with stringer technology was utilized to adjust and improve the flow section of the horizontal section. As a result, it was achieved the purpose of increasing oil and decreasing water cut. The technology has been carried out in 2 wells of Bohai L Oilfield. The average oil production of the single well was increased from 5 m3/d to 45 m3/d,and the cumulative increase oil was 6.3 ×104 m3. The comprehensive water-cut was reduced from 99% to 81%. The technology has provided a new approach for stabilizing oil production and water control in horizontal wells at high water-cut stage in offshore reservoirs with edge-bottom water.
