Three high-temperature resistant polymeric additives for water-based drilling fluids are designed and developed: weakly cross-linked zwitterionic polymer fluid loss reducer (WCZ), flexible microsphere nano-plugging agent (FPM) comb-structure lubricant (CSP). A high-density saturated brine-based was developed deep drilling. The WCZ has a good anti-polyelectrolyte effect exhibits the API less than 8 mL after aging in salt environment at 200 °C. FPM can reduce by improving quality of mud cake...
Currently, conventional polymeric filtrate reducers with high-temperature resistance for use in drilling fluids have high molecular weights, which greatly affects the rheological properties. Therefore, to address challenges regulating rheology and filtration performance of high-density at temperatures, it is essential develop low-molecular-weight resistance. In this study, a reducer (LMF) was prepared via free radical polymerization from acrylamide 2-acrylamido-2-methyl-1-propanesulfonic...
Clay-brine process employing activated clay, NaCl, HCl, and HF as raw materials is the primarily advanced technology to synthesize cryolite in present industrial grade. However, plenty of byproducts fluorine-containing waste HCl at concentration about 10%~12% could not be utilized comprehensively are even hazardous environment. This work proposed a new two-step prepare inorganic polymer flocculants polyaluminium chloride (PAC) from synthetic mother liquor. Many specific...
After synthesis of mixed fatty acid triethanolamine ester surfactant based on animal and vegetable oils, the reaction solution was added into 4% (wt/wt) liquid nitric or 9% solid as eliminating fluorescent agent continuing to react from 1 2 hours. The low fluorescence lubricant named E167 for drilling fluid prepared, in which maximum intensity (<mml:math xmlns:mml="http://www.w3.org/1998/Math/MathML" id="M1"><mml:mrow><mml:msub><mml:mrow><mml:mi...
Abstract Due to high temperature, pressure, and gypsum-salt formations in the Tian Mountain Front Block Tarim Basin, stability rheology of traditional polymer drilling fluids are difficult maintain, so sulfonated (SDF) recommended drill deep formations. The can provide a powerful technical support for achieving quality drilling, it has been run above 200 wells past year. However, large number cuttings generated operation. These contain harmful substances, including petroleum hydrocarbon,...
Abstract Due to the existence of extremely high temperature, pressure thick evaporite bed and brine layer, Kuqa piedmont structure has been identified as one most complicated drilling regions in world which locates Tarim Basin China. In Keshen Block occurrence rate invasion during progress is up 56%, barite OBM mud easy settle under temperature longtime static conditions. Therefore, settlement are serious challenges for ultra-deep wells Western Increasing density method deal with drilling,...
Drilling fluid systems for deep and ultra-deep wells are hampered by both high-temperature downhole environments lengthy cycle periods. Suppose that the gel particle-plugging agent, primary treatment agent in system, fails to offer durable stable plugging performance. In such a scenario, borehole wall is susceptible instability landslide after prolonged immersion, leading accidents. this study, novel core-shell particles (modified ZIF) with ZIF employed as core material...
Brine water based drilling fluids have advantages on protecting reservoir and stabilizing well hole, meanwhile, it also some defects such as low lubricity strong corrosivity, especially the already become an important problem demanding prompt solution.Focusing problem, a new lubricant named BLC that suit for brine were prepared.As basic material of BLC, recycled animal vegetable oil REO was made in to special intermediate product SPP-REO good lubricity, heat resistance salt by using three...
Emulsion type lubricants made from mineral oil, animal plant oil and surfactant with its good comprehensive lubrication performances commonly used in water-based drilling fluids.However, the stable preparation techniques stability improvement of emulsions have been two problems restricting their uses.In this experiment, Through use composite Pickering emulsion stabilizer which consists kinds fine particlesfiber chain bunch attapulgite clay feather sheet precipitation gas-phase white carbon...
In the process of developing deep oil and gas resources, problem high temperature salinity in strata has become a serious challenge faced by water-based drilling fluids. Under conditions, fluids must maintain good rheological properties to ensure safe efficient work. this study, temperature- salt-resistant viscosifier (DASL) was synthesized using N, N-dimethylacrylamide, 2-Acrylamido-2-methylpropane sulfonic acid, sodium p-styrene sulfonate, lauryl methacrylate as monomers with double...
Deep and ultra-deep drilling technology development is critical to the exploitation of oil gas deposits. As number wells increases, bottom hole temperature certain approaches 250°C. The high-temperature high-pressure environment can influence stability longevity instruments, as well density, rheology, fluid, making wellbore difficult maintain. Problems such high torque friction affect safety downhole efficiency. Adding lubricant fluid an effective way. In this study, choline chloride (ChCl)...
