针对部分油藏非均质性强，剖面矛盾突出，储层微裂缝发育，油井多方向见水，含水上升速度快，治理难度较大， 产能恢复率低的情况下。为了改善注入剖面，治理水驱优势通道，实现井组内对油井控水稳定的目的，公司积极研发和 生产了 PEG-1 复合型交联堵剂，目的是形成物理屏障，封堵微裂缝，高渗带等水驱优势通道，有效均衡水驱，扩大水驱 波及体积，提升油藏开发效果。 Some reservoirs are characterized by strong heterogeneity, prominent profile contradictions, developed micro fractures, multi-directional water breakthrough in oil wells, rapid water cut rise, difficult treatment and low productivity recovery rate. In order to improve the injection profile, control the dominant water drive channel, and realize the goal of stable water control in the well group, the company has actively developed and produced PEG-1 composite cross-linked plugging agent. The purpose is to form a physical barrier, plug micro fractures, high permeability zone and other water drive advantageous channels, effectively balance water drive, expand water drive swept volume, and improve reservoir development effect.

HDL 所研发和生产的 PEG-1 的主要特点有： The main characteristics of PEG-1 developed and produced by HDL are as follows: 1.该产品具有变形虫特点，具有一定的可动性，这种可动性有 利于扩大调堵水的作用范围，提高堵水效果； 2.颗粒凝胶地面交联产物，解决了常规地下交联堵水剂进入地 层后，因稀释，降解，吸附等各种复杂原因造成的不成胶的问 题；3.具有较好的选择性进入能力，有利于减少调剖剂对非目的层 的伤害。可通过适当选择颗粒堵剂在非目的产油层形成表面堵 塞而顺利地进入水驱大孔道，从而达到堵水剂选择性进入封堵 层位目的； 4.可根据施工地实际条件先择适当膨胀倍数和强度地微粒。 1. The product has the characteristics of amoeba, and has certain mobility, which is conducive to expand the action range of water regulation and water shutoff and improve the water plugging effect; 2. the surface crosslinking product of particle gel has solved the problem of non adhesive caused by complex reasons such as dilution, degradation and adsorption after conventional underground crosslinking water plugging agent has entered the stratum. 3. It has good selective entry ability, which is beneficial to reduce the damage of profile control agent to non target layer. By properly selecting the particle plugging agent to form surface plugging in the non
