The Development and Application of a Novel Polyamine Water-based Drilling Fluid

Petroleum Science and Technology (2013)

Hanyi Zhong Zhengsong Qiu Weian Huang J.C. Qiao Huaming LI

Polyamine water-based drilling fluid has been used around the world in recent years. The authors investigated the key additive SDJA-1 as polyamine shale hydration inhibitor. Results indicate that SDJA-1 can suppress clay hydration effectively and provide a pH buffer effect. Polyacrylamide and nano-emulsion ZX-8 were selected as shale encapsulator and lubricant, respectively. The properties of polyamine water-based drilling fluid including inhibition, lubrication and toxicity were evaluated compared with other inhibitive water-based drilling fluids and conventional oil-based drilling fluid. Results show the fluid outperforms other water-based drilling fluids and approaches to the performance of oil-based drilling fluid. Furthermore, the system is non-toxic and environmental friendly, superior to oil-based drilling fluid. This system was successfully applied on well Tian 310 in Shengli oilfield. A caliper log was run which indicated the highest quality wellbore ever recorded in the entire block.

A Novel Hydrophobically Modified Polyacrylamide as a Sealing Agent in Water-based Drilling Fluid

Petroleum Science and Technology (2013)

Binqiang Xie Zhengsong Qiu Jie Cao Weian Huang Hanyi Zhong

Novel hydrophobically modified polyacrylamide (HMP) copolymers based on octadecyl dimethyl allyl ammonium chloride (C18DMAAC) were synthesized by homogeneous polymerization. The sealing performance of the HMP as sealing agent in drilling fluid was studied. The results showed that HMP-3 containing 0.66% (molar ratio) hydrophobic monomer gave the best sealing property. Compared with the traditional sealing agent, HMP-3/clay could seal the cores of different permeabilities effectively by forming a low-permeability barrier with the help of bridge material. Permeability recovery test indicated that the recovery rate of cores treated by HMP-3 systems was over 90%. The particle size analysis showed that the grain distribution of drilling fluid system can be changed by HMP-3, and the system containing HMP-3 component covered a much wide distribution, so it can be used in a wide range of pore sizes and permeabilities without foreseeing the size of pore throat definitely. This work has provide a new idea to solve the seepage losses of microfractured formations.

Inhibition Comparison Between Polyether Diamine and Formate Salts as Shale Inhibitor in Water-based Drilling Fluid

Energy Sources Part A Recovery Utilization and Environmental Effects (2015)

Hanyi Zhong Weian Huang Zhengsong Qiu Jie Cao Binqiang Xie

In this article, the inhibitive properties of polyether diamine and formate salts (mainly sodium formate and potassium formate) were compared through a bentonite inhibition test, a shale hot-rolling dispersion test, and a particle distribution test. The inhibitive mechanism of polyether diamine and formate salts was analyzed via zeta potential measurement, X-ray diffraction analysis, modified montmorillonite water adsorption test, and activity test. The results indicated that, compared with formates, polyether diamine can reduce the interlayer spacing of hydrated clay utmost and lead to clay dehydration with low concentration. Meanwhile, adsorption of polyether diamine onto a clay surface renders the clay surface more hydrophobic, while formate salts prevent clay hydration mainly through lowering the solution activity.

Effect of Cycloaliphatic Amine on the Shale Inhibitive Properties of Water-Based Drilling Fluid

The Open Fuels & Energy Science Journal (2015)

Hanyi Zhong Dong Sun Weian Huang Yunfeng Liu Zhengsong Qiu

In order to improve the inhibitive properties and high temperature resistance of shale inhibitor, cycloaliphatic amines were introduced as shale hydration inhibitors in water-based drilling fluids. Bulk hardness test, shale cuttings dispersion test, bentonite inhibition test and water adsorption test were carried out to characterize the inhibitive properties of the novel amines. Surface tension measurement, zeta potential measurement, XRD, contact angle test, SEM and TGA were performed to investigate the interaction between the cycloaliphatic amines and clay particles. The results indicated that cycloaliphatic amines exhibited superior inhibitive properties to the state of the art inhibitors. Moreover, the amines were high temperature resistant. The hydrophobic amine could intercalate into the clay gallery with monolayer orientation. The protonated ammonium ions neutralized the negatively charged surface. After adsorption, the hydrophobic segment covered the clay surface and provided a shell preventing the ingress of water.
