本文评述了近几年在文东油田近开地带解除盐堵的研究、应用成果,主要是化学解堵剂的筛选、评价及包括向地层挤化学药剂解堵、连续接水微渗透淡化解堵、过桥系结合化学药剂冲盐解堵等一套解堵技术。

This paper introduced the physical properties of reservoir and the completion method of Chengbei and Suizhong 36-1 oilfield. The mechanism of water-sensitive plugging, acid-sensitive plugging, solid particle intrusive plugging, fine particle migration plugging, formation scale deposit plugging, sump oil plugging and formation sand production plugging in water injection wells of two oilfields was studied by cation exchange capacity determination of core, volume flow test, dynamic deposit test and theoretical...

This paper introduced the physical properties of reservoir and the completion method of Chengbei and Suizhong 36-1 oilfield. The mechanism of water-sensitive plugging, acid-sensitive plugging, solid particle intrusive plugging, fine particle migration plugging, formation scale deposit plugging, sump oil plugging and formation sand production plugging in water injection wells of two oilfields was studied by cation exchange capacity determination of core, volume flow test, dynamic deposit test and theoretical prediction, the test of the effect of temperature variation on the permeability of water phase, the sensitivity test and on-site water-injection data. The main reasons resulted in plugging in water injection wells of Chengbei oilfield were water-sensitive plugging, sump oil plugging, solid particle intrusive plugging and formation sand production plugging; the reasons for Suizhong 36-1 oilfield were sump oil plugging, solid particle intrusive plugging, formation sand production plugging and scale deposit plugging. This paper provided the basis for choosing plug removal method, developing plug removal agent, choosing scale inhibitor and carrying out plug removal. It had a directive significance for water flooding in two oilfields.

介绍了埕北油田和绥中36—1油田的油藏物性和完井方式,通过测定岩心阳离子交换容量、体积流过量试验、动态结垢试验与理论预测、温度变化对水相渗透率的影响试验和敏感性试验结果及现场注水资料对两油田注水井水敏性堵塞、酸敏性堵塞、固体颗粒侵入堵塞、微粒运移堵塞、地层结垢堵塞、污油堵塞和地层出砂堵塞的机理进行了研究,得出造成埕北油田注水井堵塞的主要原因是水敏性堵塞、污油堵塞、固体颗粒侵入堵塞和地层出砂堵塞;绥中36-1油田造成注水井堵塞的主要原因是污油堵塞、固体颗粒侵入堵塞、地层出砂堵塞和地层结垢堵塞。为解堵方法的选择、解堵剂的研制、防垢剂的选择和解堵施工打下了基础,对两油田的注水工作具有指导意义。

It is difficult to utilize the conventional method to acidize the Gaoshangbao deep formations of Jidong oilfield because the burial depth of the reservoir is deep, the temperature is high, the heterogeneity among and in layers is serious and the content of mineral sensitive to acid is high. On the basis of indoor experiment, 2 wells have been acidized by means of the following process: flush the well before acidizing, remove the organic plugging by injecting organic plug removal agent, dissolve the carbonate...

It is difficult to utilize the conventional method to acidize the Gaoshangbao deep formations of Jidong oilfield because the burial depth of the reservoir is deep, the temperature is high, the heterogeneity among and in layers is serious and the content of mineral sensitive to acid is high. On the basis of indoor experiment, 2 wells have been acidized by means of the following process: flush the well before acidizing, remove the organic plugging by injecting organic plug removal agent, dissolve the carbonate cements by injecting the pad fluid, do not back flow the residual acid, inject water in time and so on. Certainly, the host acid is consisted of the retarded acid with the characteristics of high temperature resistance and low damage. At the same time, the sandstone acidizing real time monitoring system is used to monitor the operation quality. This series of matching techniques not only helps to attain to the aim of injection increase in water injection wells, but also helps to deepen the cognition to the physical property, connectivity, water intake capacity of separate zones, contamination degree of reservoir and so on of the target zone. The effect is obvious.

冀东油田高尚堡深层区块酸化增注存在储层埋藏深、温度高、层间层内非均质性严重、酸化反应矿物含量高等问题。在室内试验研究的基础上,现场采用了酸前儿井,注入有机解堵剂解除有机堵塞、前置液溶解碳酸盐胶结物,主体酸采用耐高温低伤害缓速酸液体系,不返排残酸并及时注水等工艺措施对2口井进行了酸化处理,使用砂岩酸化实时监测系统实时监测施工质量。形成了酸前地层评估、耐高温低伤害缓速酸液体系、酸化工艺参数优化设计、酸化现场实时监测与评估、酸化施工及效果评估等酸化配套技术。不仅达到了注水井增注的目的,而且加深了对注水井目的层的物性、连通性、分层吸水能力、储层污染程度等的认识,取得了显著的效果。
