随着辽河油区进入中后期开采,海上油田将成为实现可持续发展的重要产能接替区。W油田是辽河海上稠油整体开发的第一个区块,对于辽河千稳吨稳产起着至关重要的作用。该区块在常规开采阶段取得了一定的经济效益,但在开采过程中也暴露出一些问题。目前该油田处于蒸汽吞吐试验阶段,蒸汽吞吐在辽河油田稠油区块应用广泛,并且技术成熟,但受海工条件等客观因素的制约,在海上应用还面临着很多亟待解决的难题。通过建立典型井数值模拟模型,进行热采优化设计研究,现场应用后取得了较好的效果。
With the Liaohe oilfield entering the middle and late stages of mining, the offshore oilfield will become an important succession of production to achieve sustainable development. W Oilfield is the first block of the overall development of heavy oil in the Liaohe River and plays a crucial role in the stable production of Thousand-tons of Liaohe River. The block has achieved some economic benefits in the conventional mining stage, but some problems have also been exposed in the mining process. At present, the field is in the stage of steam huff and puff test. Steam huff and puff is widely used in the heavy oil block of Liaohe Oilfield and the technology is mature. However, due to the constraints of offshore conditions and other objective factors, many problems are still to be solved at sea. Through the establishment of a typical well numerical simulation model for thermal recovery optimization design and research, field application has achieved good results.
