摘要:
 为减小地层出砂砂粒、钻屑、高冲蚀性固相杂质冲蚀测试工具,避免地层塌陷及工具卡堵等,分析了地层出砂的自然因素和人为因素,提出了地层出砂的力学机理,阐明了地层出砂对地面测试工作造成的设备损坏、套管损坏及测试数据不准确等不良影响。通过采取井下工具结合填砾滤砂及地面测试增加滤砂工艺等方式对常规测试工艺进行防砂滤砂优化,从而除去流体中携带的砂粒。通过A区块T#3探井测试,选用井下工具结合填砾滤砂在井下通道中进行第一道滤砂;地面流程中采用除砂器依靠离心力和重力作用进行第二道除砂,过滤后的流体通过滤网和除砂筒之间的环形空间进入下游测试流程,除砂后流体中砂比达到002%以下,保证了测试工作的连续性。该工艺能减少砂粒对套管和测试设备的损害,提高了测试施工成功率,在地层出砂井的测试施工中取得了较好效果。
Abstract:
 To minimize the erosion on testing tools by sand, cutting, and highly erosive solids in formations and eliminate the possibility of formation collapse and tool sticking, the natural and human factors for formation sand production were analyzed, the mechanical mechanism of formation sand production was highlighted, and the negative impacts of sand production on surface testing (e.g. equipment damage, casing damage, and inaccurate testing data) were illustrated. Through application of downhole tools together with grave packing, sand filtering, combination of surface testing with sand filtering and other techniques, conventional testing techniques were optimized in view of sand control and sand filtering in order to remove sands carried in fluids. In Well T#3 in Block A, downhole tools together with gravel packing and sand filtering techniques were used as the first defense against sand production in flowing channels. Desanders were used on ground surface to provide the second defense against sand production by removing sands under centrifugal and gravity. Filtered fluid was delivered to downstream testing procedures through the annulus between filter mesh and desand barrel. Sand ratio in filtered fluid was below 002%, so that continuous testing operation can be maintained. By minimizing damages of sands to casing and testing tools, the technique can enhance success rate of testing operations. It has been satisfactory applied in testing for wells with formation sand production.
