摘要:

涩北气田是我国第四大气田,其储层为第四系粉砂岩和泥质粉砂岩。这些岩石胶结疏松,出砂严重,气水层间互,防砂难度极大,属世界性难题。研究了纤维复合高压充填无筛管防细粉砂技术系统――储层预处理技术(使用带正电支链的软纤维吸附细粉砂颗粒成颗粒集合体来稳砂)、纤维复合体技术(纤维-树脂砂三维网状复合体挡砂)和高压充填技术(不压开地层充填纤维化合物在水泥环外形成类筛管,达到无筛管防砂目的,并解除近井带损害和增加泄气面积)。该技术可达到防砂和增产双重目的,在涩北气田涩7- 1 - 4井应用取得很好的效果,不出砂产量平均增产到原来的2 .1倍。介绍了纤维复合高压充填无筛管防细粉砂技术的理论、实验、施工设计和现场应用。

Abstract:

Sebei gas field is the fourth one in China. Its pay-zone is unconsolidation Qua ternary fine-silty and dirty sandstones, alternating with gas and water layers,  with severe sand production. Grain size of the sand is very fine, so sand contr ol here is very difficult, it is cosmopolitan puzzle. We have succeeded in appl ying a series of techniques of comprehensive sand control using fiber-complex p ack. The technique uses formation pretreatment (soft fiber, its branched chain w ith electric charge adsorbs on fine siltstones and forms big aggregations of fin e siltstones.). special fibers and resin-coated sand complex to stabilize pack.  Using high pressure pack to form the fiber complex annularity of well and to in crease productivity, It bypasses near well bore damage. This combined rehabilita tion technique enables screenless sand control completion. The technique was app lied in Se 7-1-4 well;  the results are remarkable. After the sand control tre atment, sand was not found even the gas production rate is 2 1 times that of be f ore. This paper presents lab study, operation design, well selection principle,  field operation and result analysis about the sand control techniFormation que.

Key words: Fiber-complex, High pressure pack, Screenless sand control, pretreatment.
