Polymer-lignosulfonate stabilizing agent of fresh water and inhibited drilling mud, polymer basis for circulation systems P-HKR. ТУ У 24.1-23557449-002:2006
BASIC PHYSICAL PROPERTIES:
- General characterization:: Condensed lignosulfonate-acrylic agent;
- Water solubility: 100%;
- Appearance of the ready-to-use reagent: Viscous dark-brown fluid with a faint specific smell;
- Solids content in the reagent: 25%;
- Reagent density: 1110-1150 kg / m3;
- pH: 7,0-8.0;
SCOPE AND APPLICATION
- Lignopol - fresh reagent stabilizer and inhibited drilling fluids and muds medium mineralization (16-18%);
- Lignopol compatible with all conventional chemical reagents used in drilling;
- The content of the drilling fluid in the reagent is in the range:
- in BRNSTF - 5-6%;
- in inhibited and mineralized - 15-20%.
ADVANTAGES
- Lignopol has a high stabilizing effect. In systems inhibited drilling fluids Lignopol reagent consumption by at least 30% lower than traditional CSSC (KLST).
- Heat resistance Lignopol reagent system solution is inhibited at the level of 140-150 °C. The effectiveness of the reagent Lignopol at high temperatures is illustrated in the table

- Compared with the CSSC, Lignopol exhibits a significantly lower foaming ability, and causes no dispersion cuttings.
- Compared with organic inhibitors like AbramiX®, Lignopol exhibits greater resistance to salts of polyvalent metals and has minimal impact on the rheological properties of drilling fluids.
- Application Technology Lignopol agent for the treatment of drilling fluids, similar to the traditional Ukrainian technologies CSSC, and does not require special training of staff.
RESTRICTIONS
- Efficacy reagent Lignopol reduced when the content of polyvalent metal ions in the filtrate of washing liquid level exceeding 0.12%. At a higher content of polyvalent ions before application Lignopol reagent, additional processing is necessary to make soda ash mud.
- When the primary processing of drilling fluids reagent Lignopol perhaps their thickening time. This effect is enhanced at high solids content, due to contamination of the washing liquid mud cuttings.
- Application Lignopol reagent may result in the need for defoamers.
PACKAGING AND STORAGE
- Reagent Lignopol delivered to customers in liquid form.
- Delivery of drilling carried out on tank trucks.
- Storage requirements of the reagent on the rig - similar to the requirements for storage of CSSC.
- Modification of the dry reagent Lignopol-C. Upon request, dry modification reagent can be set for drilling. Lignopol-C is packed in polypropylene bags of 40 kg.
