林樊家油田是胶结疏松的常规稠油油藏,因油层出砂严重,油井必须进行先期防砂才能投产,自开发以来先后采用过绕丝管管内砾石充填防砂、涂料砂防砂和复合防砂工艺,取得了一定效果。但随着油田开发的深入,地层出砂情况越来越复杂,这就对防砂质量的要求越来越高。本文在完善和配套复合防砂工艺的基础上,将防砂、治砂与改造地层和排砂相结合,加强一次性高压充填、压裂防砂、水力喷射排砂采油等新工艺的应用,取得了较好的防砂效果。
The Lin Fanjia oilfield is a conventional heavy oil reservoir with loose cementation. Due to the serious sand production, the well must be put into operation beforehand. Since the development, the oil well has used gravel packing sand control, paint sand control and composite sand control technology, Achieved some results. However, with the development of oilfields, the situation of sand production in the strata is more and more complicated, which requires higher and higher quality of sand control. On the basis of perfecting and supporting the composite sand control technology, the application of new technologies such as sand control, sand control and reformation stratum and sand discharge, strengthening one-time high pressure filling, sand control by fracturing, sand drainage by hydraulic jetting and so on, Good sand control effect.
