随着渤海油田的不断开发,很多油井出沙严重导致失去生产能力,海上处理砂埋躺井的方式是大修再完井,常用的技术主要包括切割、打捞、倒扣、套磨铣等;传统的修井作业将切割打捞等工艺分开,其缺点就是施工周期较长、起下钻趟数较多、材料消耗较多,作业成本较高。对于我们修井作业人员而言,如何提高修井作业时效,降低成本是我们努力的方向。而采用切割打捞一体化新工艺能够提高作业时效、缩短作业周期、节约成本、同时也减小了对套管的损坏和油气层的污染。 With the continuous development of the Bohai Oilfield, many wells are seriously affected by the outflow of sand and sand. As a result, many wells are out of production and their capacity is lost. The way to dispose of sand buried in the sea is overhaul and completion. The commonly used technologies include cutting, salvage, undercutting, Of the workover operations will be cut and salvage processes such as separation, the disadvantage is that the construction period is longer, more drilling trips, more material consumption, higher operating costs. For our workover workers, how to improve workover aging, reduce costs is our direction. The integration of cutting and fishing new technology can improve operating time, shorten the operating cycle, cost savings, but also reduce the casing damage and oil and gas pollution.
