drilling fluid adhesion promoter

Description:

1.Introduction

PAC141 is a kind of hydrotrope high polymer that is copolymerized by multi-vinyl elements, it is a linear macromolecular compound, the backbone and the connection bond between hydrophilic group and the backbone are all C-C bond, so its heat resistance is not strong, the PAC141 molecular weight is heaby, the main chain is long, the molecule chain contain the COO and other active groups. PAC141 has the strong capability of adherence on the clay surface, it makes clay granule become a cross-linking net structure, so it is a high efficient adhesion promoter, and has a function of water loss dehydration. PAC141 polymer mud has a good rheological property, building capability and strong dilution shearing under high temperature, it also can repress the mud making information, and keep the stable solidity.

2.Technical parameters:

3.Application and function

--It is often used for non-decentralized polymer drilling fluid with low stolidity.

--It can improve the rheological property of drilling fluid, the shearing resistance, diluting effect, and has the function of repressing disperse, decreasing filteration, keeping the face of the wellbore.

--It is suit for all kinds of water based drilling fluid.

--Non-poisonous, no pollution.

4.Usage

To make dispergation for using, recommending to add to 1%~3%.

5.Package

Packed with triad-one composited knitting bag,each bag is 25 kg net weight.
